How do I protect my PC from spyware?

Most spyware programs are integrated into freeware that you have to install on your computer, but some are automatically downloaded when you enter a Web site. If a message pops-up on your screen proposing you install a program providing access to Web site content, don't hurry to press “OK” without checking the software. If there is no need to install some special software to view the Web site, it’s better to refuse downloading extra software.

On some Web sites you can find lists of programs containing harmful spy modules. Looking through these lists can help you learn if such programs have been installed on your computer. Sometimes PC system behavior such as slow typing, periodical alarms of installed firewalls, registration queries to unknown Web sites, system and network efficiency reduction and suspicious file discovery may indicate that spyware is inside. The best way to protect your computer from spyware is to install specialized anti-spy software.
