How to Clean an Infected Windows Computer

Viruses, spyware, trojans, worms, malware etc can easily infect a PC and can cause various symptoms like icons not working to the machine running slow or not being able to boot.

To combat this problem your PC has to be properly protected and maintained regularly. There is no point in having anti-virus or anti-spyware software installed on your machine if you never update it or run regular scans.
