Computer Viruses It is an unfortunate fact that malicious people out there consider it fun to disrupt and corrupt our computers. There seems no end to their ingenious methods of infecting us with viruses and worms that take over e-mail applications, crash systems, delete files and generally cause frustration and despair. The first line of protection is to install an efficient virus scanner, like F-Secure. But remember this is not an install and forget operation, with new viruses being produced every day, the virus scanner is only as good as it's latest virus pattern updates. Always keep your scanner up to date. SpyWare Another form of threat, not caught by antivirus programs. These can use cookies and small programs to track your Internet usage, hijack your search engines and change your home page. One of the best tools for protection is Spyware Doctor. There are free tools too, downloaded from these links: |

Trojans and Backdoor nastiness Unfortunately the virus scanner cannot protect your on-line PC from all the threats out there. Small programs called 'trojans' can infiltrate through the open ports of a PC and can then be used to manipulated and examine the contents of your hard drive. Protection from these requires a FireWall. Windows Updates A Windows PC is further subject to security 'holes' and flaws. As these are discovered Microsoft produce security 'patches', these should be downloaded from the Internet Update site. |
