I have one computer on my home network that has some strange files showing up recently. There are small applications (~ 16kb) with names that end in "hacker" like: website Hacker, Microsoft Windows Hacker, AOL Email Hacker, etc. I can't figure out where they have come from and why my anti virus S/W (TrendMicro) or my spyware programs (AdAware and Spybot) haven't eliminated them yet. Has anybody seen this behavior on their computers? They have only appeared in shared folders so far on just one computer. I'm running searches on the others to see if these apps run from machine to machine. Does anybody know if there is a patch or program that would ferret these out and eliminate them once and for all? Thanks for you help. any advice on how to protect myself right now? I'm running behind a hardware firewall built into my Linksys router but have windows xp firewall turned off. is that a mistake?
