Thank you - however I feel safer with Anti-Virus protection
looking for Microsoft viruses on linux ( except for a email server ) is mostly a wast of time
now scanning a windows install using clam from a linux install works
i have found many things on xp that Norton missed ( since dropped them and went to avg on windows ) why pay for mcaffee or Norton when clamAV
DOSE A BETTER JOB on Microsoft Windows OS's
MS viruses do not run on Linux or Mac ( yes there are some java ones that can run in the RAM - reboting removes them )
since 2004 /05 i have found ZERO viruses on Linux
i think 4 on XP using clamAV from a linux install
you are far better off using a very strong password
not running as root and not installing random packages from random web sites
SorceForge is a GOOD and trusted site
however there is NO solution for YOU installing the virus
if YOU install a program that is malicious then it is YOUR fault
look at the android APP problem with app's from untrusted sites ( read china )
if you install the virus then it's your fault .
using your " little gray cells" is the BEST defense.
