-Initial Antivirus360 infection, which has since been removed.
-Immediately following removal of av360, Windows Update fails and select programs (specifically targeted?) will load but not operate. These problems did not occur prior to av360 removal.
-An instance of iexplore.exe runs whenever explorer.exe loads, as evidenced by running explorer from cmd during safemode-prompt boot. There are no Internet Explorer browser windows, however.
I cannot run programs such as Malwarebyte's Anti-Malware (the program proper nor its installer), ComboFix, AVG8free, ATFcleaner, and Spybot S&D. Windows Defender installs and runs, but detects no problems.
Attached is my HijackThis log, but I recognize everything on it as legitimate.
As much as I dislike to, I am about to attempt a Windows XP Repair Install. I am not sure that would fix the issue, though.
And a question on my way out... Is this Antivirus360 thing spreading as fast as I think it is? I have been called out to attempt a fix for it for three separate and unrelated clients already. This is the fourth. Is it possibly evolving to account for the symptoms listed above?
I'll be around to answer any further questions.
