The reason the screen-saver virus is a problem is because the user has root access (to borrow a linux term). This allows it to do it's harm by being able to access core files

BECAUSE THE CORE OF THE O/S IS FLAWED!!

With Linux you get the same email - and it will do nothing.

Techoman said - "I never accept files on any sharing sites, I always use a external USB to test files before putting them on my Windows Xp.

Not once have I ever had a virus on Windows, being that I have used Windows see more over 10 years!"

Ok - clearly you have a need to avoid sites where potential malware exists - as your O/S is so vulnerable (don;t have to worry about that with Linux)

And you've probably never had a virus because you have anti virus software installed.

if you had told me you hadn't had a virus in 10 years and you had never installed antivirus software - Then I might be impressed (but would think you a liar - lol)

With each new security vulnerability discovered comes a new patch from Microsoft.
