Grif tells us a few more at this link -> http://forums.cnet.com/5208-6122_102-0.html?forumID=44&threadID=328220&messageID=2968150&tag=forums06;posts#2968150
The tools you noted do not find all known pests so take Grif's advice to see what else is found.
I have a dell optiplex gx270 pentium 4 2.8 gHz/512mbRAM/windows xp and I scan with avg and tune up utilites everyday but I have noticed in the processes that a number like 845746456 (thats the latest one, its a different # every time) for Administrator. I close it out, and uncheck in in startup programs but a number always comes back. Also, every now and then a few iexplorer.exe's will pop up too. I have scaned for all know viruses and spyware, including conflicker. Can anyone help me? Thanks if you can.
