You could find a friend with an up to date AV program - put your HDD as a slave (or better yet, in place of their CD drves, and you won't have to worry about jumper settongs) in their system, then run a virus check on it.
I've done this many times to recover clients infected drives.
Even if you do decide to reformat/re-install at the end of it, at least you can then save all your data first.
I mean this could mean almost anything! Please try and be more descriptive of whats happened.
I would suggest booting into Safe Mode and scanning with NAV.
Putting your Hard Drive in as a slave in another clean PC is another way to go then scan with the AV on the other PC. It'll remove the viruses but won't clear up the registry so you still get some errors after. But can deal within those later...
Sorry about the brevity of my messages so far – I am on a PC in work that only allows me to send short postings to this message board. This message has been pasted from word.
What happened was that I did an on-line viruses check on the Trendmicro website which revealed several viruses on my hard drive including ‘trojans’, ‘reg seekers’ and ‘backdoors’!
I followed their advice and deleted some entries in the registry, rebooted, got an MPEG error but windows booted up ok. Then I unchecked ‘run qjmdqpeanl.exe’ in the startup tab in msconfig – I had not seen this entry previously so thought it may contain a virus.
When I rebooted again the error described in my previous posting appeared. I have tried running safe mode but the error still occurs.
If I use the windows 98 startup floppy combined with my Windows 98 CD, will I be able to reinstall windows without losing any of my files from the PC – unfortunately I have not backed them up recently?
