Avast picked it up, but after a couple of tries, cannot get rid of the beastie.
I’ve followed an earlier thread, have run aswMBR.exe, did a scan, which found the ROOTKIT, then clicked fix and saved the log [below]. I haven’t yet restarted after running aswMBR.exe. I downloaded OTH and OTL as instructed by the thread, but am unsure where to find the scan.txt file that it mentions.
Any ideas where this exists please ?
Here’s the log:

Thanks - I’m running it now and will post the logs when it’s done.
The infected computer is my other computer, connected via LAN. I’m not sure what the source of the rootkit is, should I be worried about my main computer ? At some point on the other computer, a link was clicked [not by me!] that turned out to be one of those spoof AV programs; then lots of redirecting when doing google searches; Is that the likely source, or is it too wide a question ?
Thanks again for your help sorted this, appreciated!
ok, i’ve got the OTS log, but its huge. SHould I post a part of it, or all of it in a few posts, or is there a way to attach a .txt file ?
I’d left avast running [perhaps I shouldn’t?] and just before OTS finished and brought up the log, avast popped up a ‘threat has been detected’ message.
Here is the ANSI version of my OTS log [as one file now its ansi].
I’ve haven’t had a recurrence of the ROOTKIT warning from avast, but I did download and run MBAM … er, it discovered 868 threats that needed to be deleted …
Yep looking at that I can see why - did MBAM remove all the IFEO registry settings and the disallow run ones ?
This is a big fix so I will attach it as a text file download it to your desktop
[*]Start OTS
[*] Then press the Run Fix button and a dialogue box will pop up asking for the location - select the fix.txt you downloaded
[*]Then click the Run Fix button at the top
The fix should only take a very short time. When the fix is completed a message box will popup telling you that it is finished. Click the Ok button and Notepad will open with a log of actions taken during the fix. Post that information back here
I will review the information when it comes back in.
