Won't boot after uninstall

Avast Free Antivirus / Premium Security
1

I was having some probs installing some software and they suggested that I needed to uninstall avast to get it to install.
I wasn’t convinced but I thought there was no harm in trying (famous last words!)

So I uninstalled it (Avast 4.8 home on Vista32) and now the PC won’t boot - it gets to the bit after checking disks and then just hangs for ever.

Safe mode stops after successfully loading something like crcdisk.sys

I only rebooted a day or so before so I’m quite sure it’s an avast thing - is this a common problem?

I’ve installed windows on to a spare HDD so I can access all the files on the old system partition so if there is something that needs changing I can do that.

Thanks.

Which software?

Wow… uninstall? I see no reason for that.

It is the last file listed while booting in Safe Mode… it’s not going further and booting :cry:

From the new partition, I suggest:

  1. Clean your temporary files.
  2. Schedule a boot time scanning with avast with archive scanning turned on. If avast does not detect it, you can try DrWeb CureIT! instead.
  3. Use MBAM (or SUPERantispyware or even Spyware Terminator) to scan for spywares and trojans. If any infection is detected, better and safer is send the file to Quarantine than to simple delete them.
  4. Test your machine with anti-rootkit applications. I suggest avast! antirootkit or Trend Micro RootkitBuster.
  5. Make a HijackThis log to post here or this analysis site. Or even submit the RunScanner log to to on-line analysis.
  6. Clean your Hosts file (replacing it) with HostsMan tool.
  7. Disable System Restore and then reenable it again.
  8. Immunize your system with SpywareBlaster.
  9. Check if you have insecure applications with Secunia Software Inspector.

Yeah, me too, but thought I’d go along with it so I could say to their support it was their bad - something was confusing their service so that it would hang when starting (and not be able to be killed.)
Of course that does sound like it’s that which is the problem, but I had already rebooted ok with that uninstalled.

Thanks for the other suggestions, I’ll give them a go now

I won’t trust an application that says to disable my antivirus to install.
I won’t even touch an application that says I need to uninstall my antivirus to work.
I can’t find a word in their FAQ although.
I won’t trust in the support of such piece of code team…
