Just recently I have caught this virus. At first it was redirecting my google search results but now that seems to have stopped. However AVG still pops up with messages detecting a threat. These are always in the OS(C)\Windows\Temp folder. They carry a 4 letter name and show up as 'C:\Windows\Temp\<4 letter name>.tmp\svchost.exe'. I have tried using Malwarebytes, a scanner that has never let me down. It found no threats what so ever even though AVG still come sup with these messages. Another possible side effect is that now when I go to change my theme (windows 7) the themes under the installed category show up incorrectly with a Windows 95/98 like interface (grey & drab).

Is there any other software I could use to banish this nasty virus/malware? Or an alternative so that one of you can try and help me out?

Seems to me you are NOT alone....

You could give the following a try:

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

# After the file has downloaded, disable your current Anti-Virus and disconnect from the Internet
# Doubleclick the drweb-cureit.exe file, then click the Start button, then the OK button to perform an Express Scan.
# This will scan the files currently running in memory and when something is found, click the yes button when it asks you if you want to cure it.
# Once the short scan has finished, Click on the Complete scan radio button.
# Then click on the Settings menu on top, the select Change Settings or press the F9 key. You can also change the Language
# Choose the Scanning tab and I recomend leaving the Heuristic analysis enabled (this can lead to False Positives though)
# On the File types tab ensure you select All files
# Click on the Actions tab and set the following:

* Objects Infected objects = Cure, Incurable objects = Move, Suspicious objects = Report
* Infected packages Archive = Move, E-mails = Report, Containers = Move
* Malware Adware = Move, Dialers = Move, Jokes = Move, Riskware = Move, Hacktools = Move
* Do not change the Rename extension - default is: #??
* Leave the default save path for Moved files here: %USERPROFILE%\DoctorWeb\Quarantine\
* Leave prompt on Action checked

# On the Log file tab leave the Log to file checked.
# Leave the log file path alone: %USERPROFILE%\DoctorWeb\CureIt.log
# Log mode = Append
# Encoding = ANSI
# Details Leave Names of file packers and Statistics checked.
# Limit log file size = 2048 KB and leave the check mark on the Maximum log file size.
# On the General tab leave the Scan Priority on High
# Click the Apply button at the bottom, and then the OK button.
# On the right side under the Dr Web Anti-Virus Logo you will see 3 little buttons. Click the left VCR style Start button.
# In this mode it will scan Boot sectors of all disks, All removable media, and all local drives
# The more files and folders you have the longer the scan will take. On large drives it can take hours to complete.
# When the Cure option is selected, an additional context menu will open. Select the necessary action of the program, if the curing fails.
# Click 'Yes to all' if it asks if you want to cure/move the files.
# This will move it to the %USERPROFILE%\DoctorWeb\Quarantine\ folder if it can't be cured. (in this case we need samples)
# After selecting, in the Dr.Web CureIt menu on top, click file and choose save report list
# Save the report to your Desktop. The report will be called DrWeb.csv
# Close Dr.Web Cureit.
# Reboot your computer!! Because it could be possible that files in use will be moved/deleted during reboot.

Can you try temporary disabling AVG real-time protection then empty your temporary files using CCleaner http://www.ccleaner.com/download/builds (get the slim, no toolbar). Enable AVG, run a scan and see if it'll detect the malware again.

Thanks Marianna & Donna, I'm currently trying the first suggested option (it takes quite a while to scan my HDD!) but I'll be sure to try yours next Donna if it fails.

Thanks for the swift knowledgeable replies.
