Thanks for your response - the complete Hijackthis O23 line is as follows:

"O23 - Service: ewido security suite control - Unknown owner -C:\Program Files\ewido anti-malware\ewidocrtl.exe (file missing)" Any advice on overcoming this O23 line??

Since deleting the registry folder as above, I note that a search in the Registry for Ewido still reveals about 4 other references that I could probably also delete. However, the AVG8 has installed and seems to be operating OK. But on a full system scan the scan stopped with a blue screen after about 35 mins advisng that the process was halted becasue something was trying to write to ROM - I didn't note the error code. Could this be a memory problem - I have 1GB??
