MB scan identifies malware but it reappears immediately

Recommended Posts

I was infected by System Tool a few days ago and think that I have completely removed it, HOWEVER, something is going on and I don't know if it is related or not.....XP Pro, Svc Pack 3.....when connected to the internet my modem indicator in bottom right tray is constantly lit and the hard-drive is running constantly....my email system (Yahoo) is closed and all browsers are closed.....when I disable the wireless adapter all activity slows and then stops. A scan with MB reveals the following 2 issues ("Malware.Trace"):

1. HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Desktop\host

2. HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Desktop\id

I click "remove selected" and get confirmation that they were removed successfully. I then run MB again and the 1st issue above is back. Clean it and it comes back. If I connect to the internet the 2nd issue comes back along with the 1st. I suspect my computer is being used by some botnet or spamming system, because of the symptoms described above....but I am not technical, so I need help! Thank you. Stu
