I have two computers and both are infected with Sirefef-HO and possibly more. I have attached an OTL scan log. Stupid thing won't go away!

Would use KAV to break it but it is down currently for updating and their rescue disk doesn't even see the dang thing. Avast sure picks it up though! Doesn't disinfect though :(

Welcome to BC, salemgeek2012!

A new variant of ZeroAccess has a persistent virus dropper which disguises itself pretty well. Your OTL logs show some pieces of the puzzle, but, it looks as if a removal program has taken care of a certain portion of the infection.

Since your Desktop, as well as your laptop, are involved, will help you tackle this issue one machine at a time. Otherwise, it gets too confusing.

Starting with delldesk...

Please open OTL (Vista/Seven: Right-click and select 'Run as Administrator')

•Make sure all other windows are closed.
•When the OTL console appears, click the None button at the top.

•Copy/paste the following text inside the code box into the Custom Scans/Fixes of OTL.


•Click the Run Scan button.
•When the scan completes, it opens a notepad window with: OTL.txt

Please post the OTL.txt in your reply.

Also, download: aswMBR
Save it to the Desktop.

Vista/Windows 7: Right-click the file and select 'Run as Administrator'

When promped with: This Application can use the Avast! Free AntiVirus for scanning...etc.
Select: Yes

The last line of the run in progress will provide the status of the Avast! scan.
It will say: Downloading Avast! virus definitiond database, etc.
When the Avast! scan is done, the last line changes to: Avast Engine definitions #####

At this point, click the Scan button on the lower left of the aswMBR screen.
The last line will now say "Scanning" while in progress.

Upon completion of the scan, click Save log and save it to the Desktop.
Note: Please do NOT attempt to fix anything!!

Exit the program.

Please post the new aswMBR log in your reply.
