Adware is the name that computer professionals give to computer programs that display ads on your computer, or that perform related advertising or marketing functions. In addition to showing you ads, these programs may divert your searches to advertising websites without telling you. Or they may gather your personal information for marketing purposes, also without telling you.

Some advertising programs are benign and open about their purpose. Software vendors or online service providers may offer free or reduced-price versions in turn for showing you ads on your computer. But other advertising or marketing software can be more secretive — and can turn out to be an expensive deal.

What is Adware Doing On — And To — Your Computer?

Adware that comes from reputable firms is very rarely a problem. It will ask your permission before installing itself, and provide a means for you to remove the ads. (This may mean canceling a service, or upgrading to a paid version. The important thing is that it is your choice.)

But other advertising software can cause problems. This is especially true if it installs itself without your permission. Apart from the inconvenience of seeing ads you did not ask for, it can slow down your computer. If enough hidden programs get onto your computer the reduction in performance can be substantial. You may end up having to pay to have your system professionally cleaned up so that it works properly.

Secretive advertising software can be costly in other ways. If it diverts your searches you could end paying more for products and services you buy online. And programs that secretly gather your personal information can be exploited by cybercriminals, with very costly results for the victim.

Protecting Your Computer From Shady Ads

How can you protect yourself against secretive advertising software? The first step, as for protection against all computer threats, is to be careful. If a deal sounds too good to be true, it probably isn’t true — don’t click on that link.

But even following good security practices does not provide total protection: You need tools to assist you in protecting your computer. Free virus scan is readily available, and is a helpful start — but it is not enough by itself. Free scans have limited capabilities, and generally do not detect malicious adware.

More complete antivirus protection is not free, but it is well worth the modest cost. And most full antivirus protection tools offer an option to scan for adware as well. Well-designed protection allows you to leave advertising programs that are there by permission, while getting rid of nuisance or dangerous programs that you did not ask for. Which, in turn, will help keep your computer running smoothly and safely

Using a wireless network in your home gives you the convenience of being able to use your computer virtually anywhere in your house — and still be able to connect to other computers on your network or access the Internet. However, if your wireless network is not secure, there are significant risks. For example, a hacker could:

• Intercept any data that you send or receive
• Gain access to your shared files
• Hijack your Internet connection — and use up your bandwidth or download limit

Internet Security tips — to help you protect your wireless network

Here are some simple steps you can take to protect your wireless network and router:

• Avoid using the default password
  It’s easy for a hacker to find out the manufacturer’s default password for your wireless router — and then use that password to access your wireless network. So it’s wise to change the administrator password for your wireless router. When you’re deciding on your new password, try to pick a complex series of numbers and letters — and try to avoid using a password that can be guessed easily.
• Don’t let your wireless device announce its presence
  Switch off SSID (Service Set Identifier) broadcasting — to prevent your wireless device announcing its presence to the world.
• Change your device’s SSID name
  Again, it’s easy for a hacker to find out the manufacturer’s default SSID name for your device — and then use that to locate your wireless network. Change the default SSID name of your device — and try to avoid using a name that can be guessed easily.
• Encrypt your data
  In your connection settings, make sure you enable encryption. If your device supports WPA encryption, use that — if not, use WEP encryption.
• Protect against malware and Internet attacks
  Make sure you install a rigorous anti-malware product on all of your computers and other devices. In order to keep your anti-malware protection up to date, select the automatic update option within the product.

You’re shopping online, you’ve found a great deal on a new camera, and you don’t want to miss out.

However, you’ve never heard of the retailer before. Or maybe it’s one you know, but you think there’s something not quite right about it…

Do you take the risk and buy the camera? Or do you play safe and cancel the transaction? You need some safety tips for shopping online.

Make sure you’re surfing on a safe site

Cybercriminals often create fraudulent websites, posing as high-profile online retailers. These websites look legitimate and ask you to enter personal information to verify your account. What they want is your username and password, so they can use it to hack into your other online shopping accounts like Amazon or eBay – or even your bank account. They also want your credit card information and your personal data. You want to be certain that you are protecting your money online.

How do you check if the website is safe? Well here’s a good online shopping tip; when you are in the shopping cart or on the payment page, look at the address bar of your browser. You should see ‘https’ – not ‘http’ – at the start of the URL, and a small padlock symbol next to it. This shows that you have a secure session with the website. It is a good sign and a good shopping safety tip. But there is little else to indicate you are dealing with a trusted site.

Put an end to keyloggers

Cybercriminals often write keylogging programs that run silently in the background of your PC, hidden from view. You may have accidently installed them by clicking on a pop-up or a link in a spam email. And without quality Internet security, they are practically impossible to detect.

Keylogging programs record every keystroke you use to enter your name, password and credit card details when you make a purchase. In short, they record everything you type on your keyboard.

This information is then sent back to a remote computer/hacker who could use your card to purchase items for themselves, or sell the details to other cybercriminals who use it to purchase goods to be delivered to a temporary address – stealing your money and possibly identifying you in the process.

A simple online shopping tip is to install strong internet security. Premium Internet security solutions often come with a feature called a “virtual keyboard”. When entering a username or password, an image of a keyboard appears on the screen and you can complete the process by clicking on the virtual keyboard with a mouse. This foils keylogging programs, which expect you to use the PC’s keyboard.

Put an end to keyloggers

Hackers also use your email address and password to enter different online shopping sites. People often use the same weak password for multiple accounts. Breaking just one of these accounts gives the cybercriminal access to a lot of personal data.

Another essential online safety tip is to create strong passwords for each of your online accounts including shopping sites. It is worth using these simple steps:

1. Don’t make your password an easy-to-guess word or place name
2. Use a mixture of letters (in upper- and lower-case), numbers, and even punctuation marks
3. Have a different password for each site you use
4. Record each password in the encrypted vault of your Total Internet Security solution
5. Use the password manager of your total Internet security solution.

Online shopping doesn’t have to be dangerous

We’ve given you some tips for safely shopping online because it can be minefield when cybercriminals are trying to steal your password, your credit card details and even your identity. But with a premium total Internet security solution, you can check each online store is safe, create a unique password for each site, log in using virtual keyboards to avoid keylogging and store your passwords securely on all your PCs.

Now shopping online can be just as safe, affordable and convenient as shopping on Main Street. For more online shopping tips please visit the Internet Security Center for information on internet safety and security threats.
