Most PC users now ensure they have an antivirus program installed and many take steps to deflect spam, however far fewer take the necessary precautions to protect their PCs from spyware. If software places a program on a PC designed to send back details of the user’s shopping habits, this is certainly an entirely unwelcome invasion of privacy but as it doesn’t interfere with use of computer, should you really be concerned?
The reality is that many tools leaking out information can slow down, even clog-up, Internet connection speeds. Other spyware components can hijack your browser’s startup page. Alternatively, they can make browsers crash repeatedly. Even worse, some spyware components can alter important system files without the user realizing.
The problem is that spyware can be propagated by so many areas of computer use – these include freeware and shareware programs, media players, interactive content of all kinds and file sharing. Luckily, there are lots of programs that combat spyware. Some of these tools work by rooting out and annihilating spyware components already present on systems while others prevent them from being installed in the first place. The good news is that many of these tools – most, in fact- are free for personal use so there’s nothing to stop users implementing both approaches.

Some of this trusted anti-spyware tools are Ad-Aware, Spybot, Spyware Doctor, SpywareGuard and IE-SPYAD. They are free and can be downloaded online
