I had the same virus on my machine. It is particularly nasty! In addition to redirecting search engine results, Alureon stopped my anti virus software from updating, windows update was not accessible and the virus would install other unpleasant viruses and trojans on my system. It seemed impervious to all the (many) anti-virus tools I used - either it would go undetected or would be detected but the software could not remove it. Here is what I did to eventually get rid of it, using standard free software tools:
1. Download Microsoft Security Essentials if you do not already have it (Get it here
2. You need to ensure that MSE is fully up to date. If the automatic update facility does not work then you can down load and run the update yourself here 32-bit update (XP)
/ 64-bit update (Vista/Windows 7)
3. Run Microsoft Malicious Software Removal Tool (Get it here
). This detects Alureon and partially removes it. It then recommends that you run anti-virus software to fully remove it.
4. You then need to restart your computer in safe mode. Keep tapping F8 on start up or (for XP) go to the start menu and click on "Run", type "msconfig", go to the Boot.ini and tick the checkbox next to /SAFEBOOT. It is vital that you restart your computer straight away in safe mode or the virus seems to quickly repair itself and you will need to run the Malicious Software Removal Tool again.
5. Once you are in safe mode, run a full scan with Microsoft Security essentials. This time the software should be able to completely remove Alureon.
6. Run your favourite anti-malware/anti-spyware program to pick up any nasties that Alureon installed on your system that went unnoticed by your anti-virus. I recommend Malwarebytes' Anti-Malware
. I ran Lavasoft's AdAware software which claimed my system was clean but the malwarebytes software picked up a dozen nasties that Lavasoft missed, including W32/Zbot which is a very nasty banking password stealer, which I believe Alureon infected my system with.
7. Perhaps not necessary but to be on the safe side I cleaned out all my temporary files with this tool - OldTimer's Temp File Cleaner
Hope this helps someone out there! The key is to manually update your anti-virus from the apppropriate website if auto-updates do not work and to run the anti-virus software in safe mode. I am still not 100% convinced I am rid of it, but all my subsequent scans have been clean. Fingers crossed... and good luck!
