A nasty and dangerous software devised to take partial or full control of a computer’s operation unknown to the user is a spyware. And it has taken the users by surprise. It has made a mess of a user’s control over the computer; it intrudes into his privacy, redirecting web browser activity, and, worst of all, siphon off advertising revenue to a third party. Other spyware can also be annoying and cause your computer to slow down or crash. Generally, computer problems can be exasperating. What could be worse than that? In response, online tools to catch spyware have sprung up.

But how did the spyware get into your computers in the first place? An ordinary ploy is to secretly install the software while installing other software like music or video file sharing program. So to be able to avoid spyware installations in your computers, try to read all disclosures whenever you install software in your computer. Read the fine print because sometimes unwanted software is included in the documentation. This usually can be found at the end of the privacy statement. And uninstalling unwanted software can be pretty hard. The next best thing is to download a tool to clean up the mess for you. There are lots of free and low-cost software in the Internet to help you check and remove the spyware.

The use of the free spyware cleaners online can be a good start to get rid of any spyware programs attach to your computer. You can see those advertised anywhere, like “FREE ONLINE SCANNING”, with a single click, you can sit back and watch a list of “spyware” being detected for free. But there is a snag. Once you get rid of the unwanted software with online tools, you can no longer use the free program that came with the spyware.

So you have to decide which is best for you, continue using that free software or knowing and recognizing the fact that these programs can do a lot of damage when they send your password and credit card numbers into the hackers’ hands. Spyware programs stealthily stalk the sites you surf, the business you do with eBay, and the e-mails you send. This is normally done when advertisers ask for information about products bought and sold on the Internet. And hackers found this a convenient way to steal your personal data from your personal computer.
