How To Protect Your Computer From Spyware Attacks
Spyware is more than just annoying - it can cause other programs to not work properly and can cause your computer to become quite unstable. Not to mention the privacy issues it brings up.
Spyware is often installed without your knowledge or consent and in many cases can’t be removed from your computer without specialized software tools. When the people that distribute it need to resort to tricking you into installing it, there’s obviously very little there to warrant your trust.
Your first line of defense is common sense. Be careful when you install new software. Only install software from trusted websites, and always read the license agreement. Some companies disclose that they install extra things with their software, but most people don’t read the license and never know it.
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 your system does get hit with a spyware attack, all is not lost. There are several software utilities made for getting rid of it. These programs have a database of known spyware that gets updated on a regular basis as new ones are found. They’ll scan your computer to see if anything from this database is installed on it.
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 your system is spyware free - help keep it that way. Some of the spyware removal tools include utilities that can protect your computer from being exposed to spyware. Much like virus scanners, they monitor changes to your system files and alert you of any suspicious activity.
And of course, always be aware of the risks before you accept any free offers for software on the internet. You never know what the real cost is for that free program.
