Thank you very much if anyone can help.
Running Windows XP Home Edition on emachines notebook NV51 (no recovery disk or DVD drive).
As far as I was aware, the the only anti-virus I had was Zonealarm but now I'm not sure. If I look as System processes running, I see quite a large few avg files so maybe I have avg, too.
Windows Updates started asking for persistent installation and on boot I had to wait for updates to be installed. Gradually lost XP log in functionality over several days - machine slowed progrssively to a standstill, wheezed and got very hot - ended up not being able to log in at all as user, yet could run everything fine in Safe Mode. Received Windows pop up messages that various new hardware installations were being recognised when I was not installing any.
(Hope this makes sense.)
So a couple of days ago I installed and ran ADWcleaner and FSRT
I managed to log in yesterday...... but while the desktop looked normal the eggtimer hung for ages and nothing happened when I clicked any icon.
I read this page, which advised me to run MB and Combofix.
(No mention of running it under supervision - sorry.)
MB said it had fixed 1 error.
Combofix initially could not find a restore point but then did its stuff until it hung at line 48. I left it over night and it is is now frozen at a "Deleting Files screen":
I don't want to turn Combofix off or reboot as I've since read on your site that this prog needs to be run under supervision. I'm sorry if my ignorance has made life more difficult for you guys but would really appreciate some support.
