Dear Sir,
I followed your procedure and loaded the log into Hijack Analyser but afraid the results are 'all Greek to me':-

I've tried deleting the registry values identified by Spybot, and neither CursorXP nor any ATI product is on my machine but netsearch.net keeps on returning. The netsearch entry does not seem to be affecting my comp but it's the 'not knowing' that gets you!
I'd be most obliged for your help!
Chas.
