This problem started when i received a msg on yahoo messenger, saying: "who is beside you in this pic ...so good-looking", foolishly i clicked on the msg... only to find my comp infected by some trojan or somethin.... my internet explorer homepage was permanently changed to "http://thecoolpics.net"... i then downloaded Ad Aware and Avast Antivirus, did the reqd checks, erased the trojans present, but the problem persisted. I had to shift my browser from ie to mozilla firefox. Also, Zone alarm firewall found programs "IEXPLORE.EXE" and PROJECT1 requesting access.Even now, wierd messages like the one above are randomly sent from not just my account, but from yahoo and windows messenger in general, meaning anyone who accesses their account from this comp. soon, the internet explorer icon vanished from the desktop, and i find myself not able to reach the registry or use the run command... the run command is not in the start menu nor is it found anywhere else, like in the properties of the taskbar...plz help!!! If any more info is reqd, do feel free to ask. I am using Windows XP.
