Thanks for the quick response all!

I do offer a few users that use windows, email accounts.... but i will 
suggest they grab something their end to solve that problem, and as 
someone said install something to get rid of the virus spam...

Also what is this "rootkit attacks" could someone expand of that for 
me... oh and what i might need to protect myself from them...


ps = i think i might give "ClamAV" a wiz... would anyone be able to test 
it for me once its installed?
