Glad to hear it, Hans! Although in fairness it was Colin who first suggested the solution I sent you. I've used that site in the past with good results too, though.
It's not an AV pgm... it's a spyware/malware checker, as is AdAware. Norton and AVG are AV pgms. I did state that Antivirus XP 2008 is a spyware like pgm ... not a virus.
I had a virus called "Vundo" once, damn its a PIA to remove aswell. Numerous scans using AVG and Adaware. I ended up having to go into safe mode, delete the suspicious files, run a couple of more scans, look up on the internet how to remove the thing, tried a few programs, and it still wouldnt go away. I did get rid of it eventually but i'm not sure how.
Anymore these days, it's best to reload the OS from a clean start. If you slipstream the OS and a few other desired pgms. onto an unattended install disc, it's not long effort to the process. You get a responsive running machine once again.
With regards to AVG antivirus- it sux! It terribly lags my 'puters - I mean really slow. No matter what the pgm settings, it always auto-updates (why I don't know, since the box is unchecked), it runs slower than molasses in deep space, seems to catch more fartware than real viruses, etc. My wife has good luck with it in her machine but my systems choke badly from it. My solution? UNINSTALL and stick with Norton Corporate AV. Freebie pgms. often are not all that cracked up as advertised.
