Avoiding Spyware And Malware Attacks
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.
These pieces of software are generally installed on your computer without your knowledge or consent. They often can’t be removed without some kind of specialized software. If you need to be tricked into installing it, chances are you can’t trust the source.
The best defense against spyware is common sense. Always be watchful when you download software from the internet. Don’t install software from unknown websites that you don’t know if you can trust and be sure you always read through the license agreement. Sometimes the license will disclose that spyware is installed along with the program (although usually not in so many words) but they’re counting on the fact that hardly anyone ever reads the license anyway.
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.
Some of these scanning programs are available for free, while others will cost you money. The ones you pay for generally have extra features, such as the ability to schedule automatic scans. They’re never completely foolproof however, so it’s always a good idea to run two or more of them.
Some spyware is notoriously difficult to remove. They may make several alterations to your system settings and install files in different places. Often the only way to remove this type of spyware is to find the locations of all the files and manually delete them.
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 the spyware has been removed from your system, you should run scans on a regular basis to keep it clean. Whether you do this manually or use a program that does it automatically on a schedule is up to you (and your pocketbook).
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.
