Sometimes they call you or knock on your door trying to scam you. Whatever you tell them can be used against you. They can steal your identity. If they find out you don’t have an alarm, they may break into your house. If you tell them the company your home alarm is with, they may call you at a later date posing as that alarm company and requesting “updated credit card numbers.” They can also sell you a bogus alarm system.

The Detroit Free Press reports that scammers “come door-to-door selling free alarm systems or systems for $99. Then, they lock you into a long-term contract for three to five years. The equipment is inferior. I’ve known people that have been burglarized with this equipment, and the burglars just yank the alarm off the wall and it doesn’t work.”

This issue is best resolved by not answering any questions at all, hanging up, deleting the email or telling the person at the front door (while you speak through the locked door) you are not interested. No matter what, never give the scammer your Social Security or credit card number or reveal whether you have an alarm.

Only purchase alarm systems from reputable installers, and do your research to make sure the company has been properly reviewed and vetted for a quality product.

A Virtual Private Network (VPN) is a network set up to communicate privately over a public network. A VPN protects your data between your laptop, iPad, iPhone or Android device and an internet gateway. It does this by creating an impenetrable, secure tunnel to prevent snoopers, hackers and ISPs from viewing your web-browsing activities, instant messages, downloads, credit card information or anything else you send over the network.

A proxy server (sometimes called a web proxy) generally attempts to anonymize web surfing. There are different varieties of anonymizers. The destination server (the server that ultimately satisfies the web request) receives requests from the anonymizing proxy server, and thus does not receive information about the end user’s address.

Proxies and VPNs are both designed to change your IP address and manipulate your internet browsing to allow you to access YouTube, Facebook etc. – so they will essentially unblock those restricted sites.

However a proxy doesn’t offer encryption, which means the information you are sending and receiving may be intercepted and stolen on public Wi-Fi. AVPN, on the other hand, will act both as a proxy and allow the access but also keeps your information and communication private due to encryption.

Hotspot Shield  is a great VPN option that protects your entire web surfing session, securing your connection at both your home Internet network and public internet networks (both wired and wireless). Hotspot Shield’sfree proxy protects your identity by ensuring that all web transactions (shopping, filling out forms, downloads, etc.) are secured through HTTPS—the protected internet protocol.

Now, documenting a person’s day, week, month, year, vacation or any event consists of hundreds if not thousands of photos because digital is easy and free. So what’s the best way to share all your pics in a fun, friendly and secure way? Well, that all depends on your lifestyle.

• Facebook: When taking pics from your phone, you can easily upload and instantly share your images with your connections. The beauty of Facebook photos is that all 3,000 of your friends can enjoy them and comment on them. Using your PC is even easier when you are uploading entire albums. The bad thing is, once you upload to Facebook, you can’t expect the photos to ever be private. Even though you might lock down your privacy settings so only your friends can see them, it’s still very possible that your pics can be leaked.
• Flickr: Flickr is a photo sharing site that you can always have in your back pocket via apps for iPhone, Windows 7, Android and more. Or use m.flickr.com from any mobile device to upload and share photos on the go. Share photos only with the people you want to with Flickr’s easy privacy settings. Flickr’s backed storage system makes sure you never lose another photo again.
• Instagram: Share your photos in a simple photo stream with friends to see – and follow your friends’ photos with the click of a single button. Every day you open up Instagram, you’ll see new photos from your closest friends, and creative people from around the world. Share to Facebook, Twitter, and Tumblr too – it’s as easy as pie. It’s photo sharing, reinvented.
• Dropbox: Most people don’t think of photo sharing when they think about Dropbox because Dropbox isn’t explicitly a photo sharing site. Dropbox is a free service that lets you bring together all your photos, docs and videos from anywhere. This means that any file you save to your Dropbox will automatically save to all your computers, phones and even the Dropbox website.

All of these sites require usernames and passwords for access. And like all web-based portals, I suggest a different password for each. If you install an application on your mobile, make sure your device is password protected. Another layer of protection (albeit inconvenient) is to set up these apps to require a password every time you access them.

Your device and the private data it holds are very, very attractive to thieves. Yet, most of us don’t protect our smartphones or tablets—and the private information they contain—anywhere near as well as we do our wallets and PCs.

We make life easy for them. The places and ways that we use smartphones and tablets offer new chances for criminals to catch us off our guards—in the coffee shop, on the train, while shopping. When we are using our mobile devices, we usually have other things happening around us as well as on the device. We are easily distracted. And we want what we want now. Click to download. Click to view. Click to get a free app. Few of us take the time to “think before we click.”

We store passwords, bank account information, photos, and all our contacts on these devices so we can be even more fast and efficient as we live our mobile lives. That’s why 51% of us would rather lose our wallets than our mobile phones.

Some of the things you can expose yourself to if you don’t protect your mobile device include:

Financial fraud: Someone takes over your bank account, extracts money, or sets up a premium text scam where you pay for messages you don’t want.

Identity theft: By having information about you, someone can pretend to be you and sign up for credit cards, identity papers—even buy a car. It can take years to recover your good name.

Privacy loss: Someone gets information about you that you don’t want out there, including social network activities, GPS location, searches, texts, instant messages, downloads and app usage. This information could be just embarrassing—or it could cost you a friendship, a job, your credit rating or a chance for college.

Losing your device: In addition to having to buy a new device (unsubsidized by the operator), you can give a thief the information needed for the fraud, identity theft and privacy loss mentioned above.

To ensure that you protect your smartphone and tablet you should:

Don’t click on links in texts or emails, since these links may actually point toward malicious downloads

Keep your device with you, don’t let it out of your sight and don’t share it with others.

Make sure to have a pass code on your device and set it to auto-lock after a certain period of time

Before downloading any app, check other users’ reviews to see if it is safe, and read the app’s privacy policy to make sure that it is not sharing your personal information

Carefully review your mobile phone bills for any anomalies

Use comprehensive mobile security that include anti-theft, antivirus and web protection like McAfee Mobile Security or McAfee All Access

Most malware is designed to have some financial gain for the cybercriminal. Whether they are seeking your financial account information or holding your computer files for ransom or taking over your computer or mobile device to “rent” it out for malicious purposes to other criminals, they all involve some sort of payment to the cybercriminal. And because they are making money with malware, they continue their malicious ways.

There are a number of ways that malware can get “on” your computer or mobile device. You might open an attachment from someone you know whose files have already been infected. You might click a link in the body of an email or on a social networking site that automatically down­loads a virus. You might even click an ad banner on a website and end up downloading a virus or malware (known as “malvertising”). Or just by visiting a site you could get infected from what is called a drive-by download. Malware is also spread by sharing USB drives and other portable media.

And, now that mobile phones and tablets are basically mini computers, cybercriminals are targeting mobile devices. They are taking advantage of the inherent nature of the device to spread the malware, so as a mobile user you not only need to be aware of the same tricks cybercriminals use for computers, but also ones that apply to mobile devices.

Currently most mobile malware is spread by downloading an infected app so you need to be aware of what sites you download apps from and what permissions it accesses on your mobile device. Mobile malware can also spread via text messages (SMS). Scammers send phishing messages via text (called SMiShing) to try and lure you to give up personal or financial information or sign you up to premium text messages unknowingly.

What does this mean for you? You need to be aware of these tricks and scams as it could mean financial loss, reputation harm and device damage to you and your friends.There are things you should do to protect yourself, including making sure you protect all your devices with a cross-device security software like McAfee All Access. You should also make sure to:

Keep your operating system and applications updated, as updates often are to close security holes that have been exposed

Avoid clicking on links in emails, social networking sites, and text messages, especially if they are from someone you don’t know

Be selective about which sites you visit and use a safe search plug-in (like McAfee SiteAdvisor which is included with McAfee All Access) to protect you from going to malicious sites

Be choosy about which apps you download and from which sites you download them and be sure to look at the permissions for what information its accessing on your mobile device

Be smart and stay aware about cyber tricks, cons, and scams designed to fool you

In a 2009 horror story also out of Cleveland, a convicted rapist lured a 21-year-old woman to his bedroom back in 1989, spent 15 years in jail and then got a free pass in 2005. And, of course, he did it again. Why? Because that’s his brand of normal. It’s not OK, but it’s normal in that it’s his nature. A psychologist said to me years ago, “You would be amazed at how many levels of normal there are.”

A recent report of “Brooklyn Missing Boy: Police Arrest Man the Dismembered Child Had Asked for Directions” reminded us about how there always have been predators, there are predators today and there always will be predators—and we have to take steps to protect ourselves and those we care for.

When a true stranger—not a family member, not someone known to the child—steals a child, that child often won’t survive beyond three hours.

No matter what the statistics are, child abductions are real—and they happen far too often.

The last thing you ever want to think about is your child getting taken away from you by a stranger or even someone you know. And while the statistics aren’t nearly are bad as one would think, parents think about child abduction all the time.

The old-school training a lot of us received early on was, “Don’t talk to strangers”—as if strangers were the dangerous ones. Actually, most abductions occur when a family member takes the child after winding up on the losing end of a custody battle.

Today, most so-called helicopter parents won’t take their eyes off their kids—and I don’t see that as a bad thing. I know many will argue that point, but I don’t care.

Protecting yourself and your children begins with understanding basic security.

1. As simple as it sounds, do not engage in behavior that creates an opportunity for the bad guy. Example: being too nice and accommodating. Recognize a potential lure.
2. In the event that a child were to be approached, the best defense is a good offense. Resistance has often been a proven tactic for removing oneself from a dangerous situation. Running, screaming, biting, hitting and kicking may feel unnatural to teach your kids, but they are certainly natural traits they possess. I say if they are good at it now, train them to do it better!
3. As soon as your child is at an age where he or she can comprehend this issue, it’s time to discuss it. By age four kids have a pretty good grasp, but age five they seem to be on solid footing.
4. Role play with your kids. This is a delicate balance of awareness and play. Intellectually introduce scenarios for them to respond to. See how they articulate a response. Let them figure it out on their own. Then, if they don’t give you the answer you were looking for, work with them to understand the nature of their choice and its negative impact.
5. Be specific, but be careful how you associate your analogies. Example: “If a white van pulled up next to you” will freak your kid out every time he or she sees a white van and will only make the child wary of people in vans, as opposed to those in cars or on foot.
6. Make sure to discuss the internet and online predators. I’ll discuss this in depth in a future post, but in the meantime, do your research and know what risks your kids face. Take control of their access to PCs and monitor everything they do.
7. Most importantly, this kind of education is about empowerment. It’s about taking control. It’s a gentle awareness that can very well save their lives. Don’t guilt them into making the right decisions and make them feel bad about not understanding the issue. If they aren’t ready to comprehend the issue, then back off for now.
8. Always keep an eye on people who look out of place. Don’t take your eyes off the ones who belong, either. Predators often know their victims.
9. And because your kids spend the majority of their time at home, do all the necessary things to strengthen your fort. Invest in home alarm systems. Install home security cameras inside and outside the home. Install proper fencing that keeps them in and others out.

10. Finally, live in peace and harmony. The chances that something like this can happen are very, very slim. But there is a chance, so these are your options.

But I hate having to go through the misery of disputing charges. In my own research, I’ve determined four types of credit card disputes to look out for.

Unauthorized use: Basically, this is fraud—unauthorized use of your card when someone steals the card, skims the card, copies the number, hacks the number or double charges on purpose. Under federal law, you are responsible for up to $50 as long as you refute charges within 60 days with your credit card company. If it happens to you: Contact your credit card company ASAP and begin the resolution process. BillGuard can also help you open a dispute, at no cost to you. Just click the red button on your BillGuard Scan Report.

Disputes on dollar amounts: Mistakes happen. But I often find they don’t happen in my favor. They seem to always happen in the merchant’s favor. Funny how it works out like that, huh?

You might be billed incorrectly for products or services you didn’t purchase, charged for products you ordered but didn’t get, or be overcharged. (For the record, I don’t think I’ve ever been “undercharged.”).  If it happens to you: Contact the merchant ASAP and go through the merchant’s process for resolution. Don’t want to deal with the hassle? BillGuard will handle the dispute for you, for free.

Problems with products or services: Sometimes it’s a quality issue: products break within 30 days, are delivered broken, or the merchant fails to provide services requested. If it happens to you: Contact the merchant ASAP. If the merchant is uncooperative, contact BillGuard.

Grey charges:Grey charges are often charges that, in a roundabout way (that is, in the fine print), we agreed to by purchasing products or services. A grey charge may include mysterious subscriptions, automatic renewals, free products that result in paid products or cost creep. The initial purchase may be pennies, but over time ends up costing big dollars. If it happens to you: Flag the charge on your BillGuard Scan Report. We’ll help you open a dispute.

Here’s how to reduce your aggravation when it comes to credit card disputes:

• Always reconcile your bills diligently and on a timely basis.
• Refute unauthorized charges immediately—within one to two billing cycles.
• Use a credit card instead of a debit card, as credit cards offer more consumer protection.
• Be patient—and be nice—when talking to customer support. Don’t yell like you’re some crazy Italian. (Disclosure: I am that crazy Italian.) Trust me. It usually doesn’t work.
• Use BillGuard to watch your back and help you resolve unwanted charges.

We’re all familiar with the boy who cried wolf. The protagonist of the fable is a bored shepherd boy who entertained himself by calling out “Wolf!” Nearby villagers who came to his rescue found that the alarms were false and that they had wasted their time. When the boy was actually confronted by a wolf, the villagers didn’t believe his cries for help, and the wolf ate the flock (and, in some versions, the boy).

Accidentally setting off an alarm can cost you in much the same manner.

The Santa Fe New Mexican reports that “The Santa Fe Police Department has netted nearly $500,000 from false-alarm fines and registration fees since the program began in 2010, a report says. At the same time, a business called CryWolf earned more than $271,000 from city residents and businesses for administering the program, a 32 percent fee it takes off the top of collections.”

I’m just as guilty as anyone of setting off a false alarm. But I’ve never had law enforcement show up to my home as a result.

To protect yourself against false alarms, follow these four simple tips:

1. Have your service provider set up your alarm system to call your mobile phone first, then your home phone second. If you don’t answer the phone, then they will call the police.
2. Program your mobile phone with your alarm service provider’s number and call them the second you falsely set off your alarm. Memorize your PIN so you aren’t fumbling for it.
3. Don’t carry your PIN in your wallet. If your wallet is lost or stolen, your address and alarm PIN are in the hands of a stranger.
4. Whenever setting up access for anyone to enter your home while you’re away, your risk for false alarms goes up dramatically. Provide specific hands-on instruction on how to disable and reset the alarm. Telling someone over the phone how to do it is often insufficient.

CNN reports “Built-in GPS technology means smartphones know where a person is at any given time. Phones with Facebook Home could access this information at any time to determine what businesses or neighborhoods you visit the most or even where you live. That data could then be used to serve up a more personalized ad, such as a coupon for a store you’re near or coffee shop you visit every Sunday. A Facebook representative told CNN that Home will not actively track users’ GPS location.”

Back in 2010, The Wall Street Journal was already warning us about app developers’ lack of transparency with regard to their intentions:

An examination of 101 popular smartphone “apps”—games and other software applications for iPhone and Android phones—showed that 56 transmitted the phone’s unique device ID to other companies without users’ awareness or consent. Forty-seven apps transmitted the phone’s location in some way. Five sent age, gender and other personal details to outsiders. The findings reveal the intrusive effort by online-tracking companies to gather personal data about people in order to flesh out detailed dossiers on them.2⁸

One developer of online ads and mobile apps acknowledged, “We watch what apps you download, how frequently you use them, how much time you spend on them, how deep into the app you go.”

And since then, our level of engagement with mobile apps has only increased, while no meaningful steps have been taken to prevent applications’ access to your data. The motivation here is money. The more they know about you, the more targeted ads they can deliver, and the more likely you are to buy. The information also can be abused for identity theft and other malicious purposes.

Facebook Home may have the best intentions and could very well be a great addition for any heavy Facebook user. And keep in mind, every application you install wants more access to who/what/where/when about you so they can send you targeted ads.
