Hi, I’m getting an Avast pop-up with the title ROOTKIT BLOCKED every 5-10 minutes, with Action ‘Moved to chest’. File names are 80000000.@ and 800000cb.@ and the Virus Descriptions are as the subject title.
I’ve run MBAM, OTL and aswMBR as in the stickied thread and attached the logs.
Thanks in advance

Hi, I ran Combofix, but there were a couple of issues:
1 - Having rebooted into safe mode to run Combofix, I could not disable avast! self-defense module. (i.e go to Settings → Troubleshooting, unclick avast! self-defense module, click ok. Re-open Settings → Troubleshooting and it’s still checked). As I’d started Combofix by this point (I hadn’t realised that avast was still enabled) and there didn’t seem to be anyway to prevent it from running, I let Combofix run to completion.
2 - A couple of times in the Combofix screen output there were complaints that it needed to be run in an Administrator command prompt.
I’ve attached the log from combofix.
P.S. The reported symptoms do seem to have stopped though.
It’s okay, dont worry, I can see in CF logs that everything went as it should. 
Also, Combofix is disinfect infected files and deleted malware. The logs are now clean.
How’s your computer behaving now ?
Seems to be behaving fine, no more pop-ups from Avast and nothing new in the Virus chest.
If everything is fine now, should I uninstall everything I’ve used? (Combofix, MBAM, OTL, aswMBR)
Yes, I was just waiting for your feedback. 
It is necessary to uninstall the ComboFix :
[*] Click Start (or
http://amf.mycity.rs/pg/images/VistaStartButton.png
) then Run.
On Windows7 or Vista you may use Start Search field if Run is not available.
[*] In the line of text type in (Copy) the following:
ComboFix /Uninstall
Note that there is a space between " ComboFix " and " /Uninstall " .
[*] then click OK (or press Enter ).
Wait for the uninstall process is complete.
Re-run OTL and click on CleanUp!
Just simply delete aswMBR.exe.
I recommended to you to keep Malwarebytes if you will.
It is great additional weapon to your antivirus software.
Ok, I’ve done all that
Thanks very much for all your help!
