Here is the OTL log. I can’t print screen for some reason.

5

aswMBR has made my computer crash and blue screen twice… ???

6

At what point, during the AV scan element ?

If so try running it again and from the AV scan: drop down list, select None as the scanning option.

The first time that you run OTL it should also produce an Extras file, if you can attach that.

Unfortunately you may be playing time zone ping pong as essexboy who normally analyses these is at work and is usually on the forums around 7pm (now almost 11:50am in the UK).

7

Here is the OTL extra file.
aswMBR crashes at 1%…

8

When set to none answMBR works fine. Here is the log.

9

Ok, so I tried to run a quick scan and aswMBR errors at 1% on agrdel64.exe then blue screens.

10

I see you have run combofix - could you attach that log please

11

Sorry… I’m not sure where it is…

12

It should be at C:\combofix txt

If it is not there then we will re-run it as I need to see if there is a driver remaining

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

  • IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

13

Here it is. Thanks for the help.

According to avast! I am still infected with this:
C:\Windows\assembly\GAC_32\Desktop.ini Threat: Win32:Sirefef-FQ [Drp]
:-[

17

…?

18

It may still be a remnant, but are you getting any of the other symptoms ?

Unfortunately it is 1:05am in the UK so essexboy will be in bed and normally back on the forums after work about 7pm UK time.

19

Could you re-run an OTL please with the following script

[*]Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
[*]Select All Users
[*]Under the Custom Scan box paste this in
netsvcs
%SYSTEMDRIVE%*.exe
/md5start
C:\Windows\assembly\GAC_32*.ini
/md5stop
C:\Windows\assembly\tmp\U*.* /s
CREATERESTOREPOINT
[*]Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
[*]When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
[*]Post both logs
