Remember me? The guy who boasted about never having to run anti-virus software beccause I thought I was immune? Well a couple days ago I picked up the Klez worm, just a file named kitty.scr (screensaver) that appeared on my 2nd HD one morning. Opened it up to check it out and BOOM my computer exploded. Actually just weird things started happening. I couldn't open the task manager (ctrl+alt+del) to check out what was running and everytime I donwloaded and installed a freeware anti-virus program the virus would shut it down right after I opened it (Yikes!). So I just ran a search and there's this program made specifically for getting rid of Klez which is free (but after I paid $35 for McAfee's online service whcih didn't work ). So anyway I wake up today and what do ya know McAfee spots some other Klez, this time in the All Users/Documents folder. So how does it get there? Take your pick: - I have like 10 ports open on my router (with NAT btw) for gaming (stupid EA made us open up 6-8 ports to play C&C online). Would closing most of them stop geeks from messing with my puter? - I enabled the Guest account to share files with the other 3 computers on my home network. - Maybe Klez is still somewhere on my computer making copies of itself? - No firewall software running. Even though any network guy would punch me for doing some of these things I still don't see how a person can just write files to my HD if I have that option turned off (the other computer on my network can't do that). Is it because that All Users folder has some special properties to it that alllows for more guest privilges? Thanks for any help (and be gentle ). EDIT: Ahh the problem was the box for "Allow Network Users to Change my Files" was checked on that folder, even though I never selected that option. Turned sharing totally off for that directory so I'll probably never see that damn Klez again... or will I???
