Hello,
I'm experiencing the same kind of problem many of the posters in recent threads have been having with these two nasty little buggers, namely avast! pops up every few minutes to inform that it has moved these files to quarantine but deleting them doesn't remove the problem.
The process is: C:\Windows\System32\services.exe
The files are located in C:\Windows\Installer\{73774b33-8d54-b36d-9400-3e8693a4630a}
Below you can find the MBAM log and attached OTL & aswMBR logs.
Thanks in advance.

Notes:

Thank you for the quick reply! Everything went smoothly and the pop-ups have disappeared. The system seems to be stable and running normally. Windows Update etc. are also working.

All looks good, could you confirm there are no further problems

Subject to no further problems :)
I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems
Now the best part of the day ----- Your log now appears clean :thumbsup:
A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:
Run OTL- Under the Custom Scans/Fixes box at the bottom, paste in the following
:Commands
[resethosts]
[emptytemp]
[Reboot]
- Then click the Run Fix button at the top
- Let the program run unhindered, reboot the PC when it is done
Remove ComboFix
- Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
- In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK
(http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg)
- Follow the prompts on the screen
- A message should appear confirming that ComboFix was uninstalled
Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.
We will now confirm that your hidden files are set to that, as some of the tools I use will change that

- Select folder options (Appearance > Folder options in category view)
- Select the View Tab.
- Under the Hidden files and folders heading select Do not show hidden files and folders.
- Click Yes to confirm.
- Click OK.

Malwarebytes (http://www.malwarebytes.org/mbam-download.php). Update and run weekly to keep your system clean

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit
- Microsoft Windows Update (http://windowsupdate.microsoft.com)
