Internet Security - How To Avoid Being Infected With Spyware
By: Paul Wilcox
Spyware and other types of malware are more than just a pain in the neck - they can cause other programs to malfunction and even make your computer unstable. And of course there's all the privacy issues that go along with it.
This type of software is often installed without a user's consent and often can't be uninstalled without special tools. When distributors use tricks and deception to install uninvited software, trust is destroyed.
The first line of defense against spyware is to be careful installing software. Know what's being downloaded. A large percentage of freeware or shareware programs have spyware embedded in them. Sometimes that's disclosed in the user agreement, but often not.
Check for "spyware free" guarantees on software you download. Obviously, anyone can say something is spyware free even when it isn't, but if a website has gone to the trouble to say so, it is more likely to be safe than if they hadn't.
How can you tell if you have spyware on your system? You may see pop-up advertisements even when you aren't browsing the web. Your homepage may have been changed without your consent. New toolbars are installed on your web browser which you didn't request. Your computer may be sluggish or mysteriously reboot on its own. Though, the last effect is usually a virus.
If you find your system bogged down with spyware, don't give up hope. There are several utilities specifically designed for removing spyware from your computer. They rely on frequently updated databases which contain signature files of all known spyware and adware. They scan all the files on your hard drive and alert you if 'uninvited guests' are found.
Many are free, though sometimes the paid versions have more automation features such as removing spyware on receipt rather than requiring a manual scan. None will find every piece of spyware on your system, since they rely on a database which has to be populated according to someone's judgment. And, one man's spyware is sometimes another's welcomed advertiser.
Some kinds of spyware are notoriously difficult to get rid of. They may make changes to your Windows files that help them hide from the scanners. On occasion, you may need to delete them manually to be sure they're gone.
Needless to say, this should be performed only by skilled users. Deleting the wrong files can damage your programs and even your operating system.
Once you've got rid of any spyware on your computer, you can help keep it clean by running a scan on a regular basis. Whether this is scheduled, or you do it manually is up to you.
Of course, you need to always be wary of anything you download. You never know when there is going to be a significant cost to that free software that looks so cool.
