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 will you know if you’ve been infected by spyware? Some of the most common problems include unusual pop-up ads, a change to your homepage, new toolbars showing up in your browser and your computer acting strangely, such as freezing up or rebooting out of the blue.
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.
Some of these programs are free while others will cost. The paid versions sometimes have additional features, such as automatic scheduled scans. None of them are 100% foolproof however, so it’s a good idea to run more than one of them.
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.
This is obviously not something you should undertake unless you’re quite familiar with Windows and working with system files. You wouldn’t want to delete something that renders Windows inoperable.
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.
