I have been having some malware problems on my XP netbook within the last day or so, and was wondering if someone could help. About a day ago, I ran into problems with Security Suite 2009 telling me that many of my applications were infected. I am running McAfee Security Center that I recently purchased an upgrade for, but McAfee was only able to detect some trojans and block them. I ran Malwarebytes AntiMalware, found the Security Suite infections and removed them.
However, I was still having problems with Google redirects--more so with IE8 than Firefox 3.6.8 but I still get them on Firefox. I ran MBAM once again and did not find any infections. I downloaded and ran TDSSKiller, but TDSSKiller also found no infections.
I finally downloaded and ran Hitman Pro 3.5.6, which told me that C:\Windows\explorer.exe was infected, but when I tried to fix it, I wasn't sure if I was supposed to delete explorer.exe. I tried to click "Quarantine" but it didn't seem to work. Hitman Pro scanned my computer each time I rebooted, and each time told me the explorer.exe was infected.
I also ran Combofix in Safe Mode (I am sorry, I didn't know I wasn't supposed to run it...I am moderately comfortable with IT stuff), and it told me that c:\System32\winlogon.exe and c:\Windows\explorer.exe were infected. Combofix didn't fix these two files, though.
What would you suggest? Are ther any other tools I should try?
I can try to find the Combofix logs and post them to the other forum. Please let me know what you think. I do not have a recovery disk but I may be able to copy (a different version) of explorer.exe from another XP computer.
