Before yesterday already my computer, running WindowsME, was in trouble. My anti-virus program ground to a halt at nsexec.dll. Previous to that it found Win32/Adware.Toolbar.Yahoo.A. and there was no way to quarantine, or delete it. ScanDisk thorough only is completing in Safe Mode and it takes most of the day to do this. When I installed Spybot's newest updates to-day it discovered something different. The scan stops at NCast even when run in Safe Mode. Can you give me a clue as to what I could be trying next ?
