My antivirus software (avast 5) detected a virus on my laptop. I proceeded to clear it. A couple days later I noticed google would redirect me to other websites, and on the second attempt it would not connect to the website. Also I could not connect to certain websites like avast.com or microsoft.com. I scanned my laptop again but nothing was detected. I decided to restore my laptop back to before when I got the virus. It seemed to fix the problem with redirecting and loading avast.com and microsoft.com. I then attempted to use Windows Update to update my laptop but it will not connect and gives the following error message:

Code 80072EFE Windows Update encountered an unknown error.

I think ran Microsoft Fix it 50202 both in Default and Aggressive modes and still gives the same error code. The redirecting issue has also reoccurred on some links.

I have a Compaq Presario C700 running Windows Vista Home Premium Service Pack 2, 32 bit Operating System, Intel Pentium Dual CPU 1.73 GHz, 2.00 GB RAM

Anyone know how to fix this?

If more info is required I will gladly provide it.

Hey, just incase anyone else is having the same problem, TDSSKiller seems to have fixed the problem!
You can get it from the following link:


Also go to C:Windows>System32 and delete Catroot2 folder. If there are more Catroot2, for example Catroot2(862) then delete them too. When your computer restarts a new Catroot2 folder will be created, this is normal.

Save it to the desktop, extract it there then run the scan. Takes like 2 mins then will reboot the computer and Windows Update should work. It also has fixed the redirecting problem.

Running malwarebytes afterwards or before is also a good idea.
