*I'm getting a 'Error 524: timeout occurred' message when I try to post a full post with logs. I'm going to try attaching the logs instead as .txt files*
Our desktop is running very slowly (8 minutes from switch on to Firefox loading)
and programmes are freezing and crashing. Sometimes when I start Firefox a red screen
loads with a message warning of infection and instructing me to call an 0800 number
(presumably a scam): the URL is ftp://3-333x000000i01-virus.com. When I try IE instead,
a 'site certificate' pop-up appears and keeps reappearing no matter what I do, preventing
Java updates are failing at the end of the install. Software like Picasa is not running properly,
e.g. fails to find certain files and freezes or crashes.
A pop-up for 'Teamviewer' (not something I have installed myself) sometimes appears on starting
Avaast freezes before completing a scan. I uninstalled it and tried Avira, which does the same thing
and won't launch at all in safe mode (neither will Trojan Remover).
In safe mode, Windows explorer keeps crashing.
My computer knowledge is pretty basic but using google I have tried a few things.
I ran CHKDSK in safe mode. It found an incorrect value but crashed before I could note it.
I ran System File Checker in safe mode. Windows Resource Protection found corrupt files but was unable to fix
some of them. Explorer crashes before I can save the log.
RKill, Trojan Finder, Hitman Pro and Malware Bytes all find no results.
Your help is much appreciated.
