VIRUS WARNING - ADOBE READER "Error" - DO NOT CLICK "OK"

quoia

Sorry for the delay in replying

The GOOD NEWS is that my PC is sorted

The original problem, (Kaka 2009 ?) looks as though the restore I did sorted that out.

Definitely not had the same problem again.

However that did leave the subsequent issue of the SVCHOST.exe process using loads of CPU time and IE windows spuriously opening up, or being redirected, to "dodgy" or unrequested websites.

After a while I started getting an AVG threat warning for the PAKES Trojan infection
This manifested as every 5 to 6 minutes a file (svchost.exe) being created/opened/accessed in a folder xxxx.tmp (xxxx = any 4 random letters) under C:\WINDOWS\Temp

Anyway I had a quick Google for combinations of Pakes Trojan SVCHOST etc and came across a very similiar reported problem that had been resolved.

The specific bit I needed was

Go to http://support.kaspersky.com/viruses/solutions?qid=208280684

and Download TDSSKiller.zip to your Desktop.

Extract its contents to your desktop and drag TDSSKiller.exe on the desktop, not in the folder.

Start > Run and copy/paste the following command into run box and hit Enter.

"%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt -v

If TDSSKiller alerts you that the system needs to reboot, please consent.

When done, a log file should be created on your C: drive named "TDSSKiller.txt"

It basically found

Results:
Memory objects infected / cured / cured on reboot: 3 / 3 / 0
Registry objects infected / cured / cured on reboot: 0 / 0 / 0
File objects infected / cured / cured on reboot: 1 / 0 / 1

The infected file object was

C:\WINDOWS\system32\drivers\atapi.sys

Hope this might be of use to anyone with the same or a similar problem.
