Hi everybody, I was recently informed by my ISP that some spam had been traced to my IP address, due to an "open proxy" as the result of some kind of virus or worm. I thought that was impossible, because AVG Antivirus, Ad-Aware, and Spybot Search & Destroy all came up clean. I further tried Stinger, as well as Microsoft's spyware removal tool. None of these found anything. My ISP suggested I try ClamWin Antivirus I discovered I had "Worm.Mytob.Gen-6" on my system. AVG did not detect this. A google search indicated that neither Norton nor Symantec has this virus in their databases either. I recommend anyone who is suspicious they may have a virus give ClamWin a try. It is freeware. I have no connection to the company and no reason to vouch for them except that they did the job where other programs have failed.
