Viruses Not Detected By Norton or McAfee
Posted on 2004-09-27
Hi, guys sorry to bother you, but I have this nasty problem that I can't solve.
OS: Windows XP Home Pre-SP2
Sympton: 1) Everytime Windows starts, my Symantec Antivirus get shutdown and won't start. 2) Ctrl-Alt-Delete brings up the taskmanager for 0.5 seconds, and it dissapears 3) "msconfig" at Start->Run results in no response. 4) Running "Hijackthis" also results in no response.
What I have tried: 1)Rebooted into safe mode, Ran Symantec Antirus (succesfully) and updated the latest definitions, and did a full system scan, but it found nothing 2) Under safe mode, Ran Adaware with the latest defintions, found 10+ spyware and removed all of them. 3) Ran Hijackthis under safe mode, and removed all suspicious entries 3) Went back to normal mode, and the problems still persist. I downloaded a copy of Nod32, and it also refuses to run (appears for a split second and dissapears).
HOWEVER, if i rename all those files that refuse to run, they all run succcesfully. So I know the virus has a list of filenames somewhere that it prevents them from running. So I ran nod32 (renamed) 's system scan, and it found a couple of viruses that Symantec did not pick up, and I deleted all the infected files, but the problem STILL persists.
Right now, I am not experiencing any real problems other than those files not being able to run. I'm am just confused as to why wouldn't Symantec pick up those viruses, and why do those symptoms still exist even when nod32 cleaned them....
Any advice as to what to do?
Thanks a lot!!!!!
