Hi and thanks from the get-go to whoever may be able to offer me help. Recently my computer was infected by some sort of malware. I'm sure that a.exe and msa.exe were part of this but it seems that a browser redirector is included as well. Here's what I have: Windows XP SP3 with Zone Alarm, Avira, and PC Tools Spyware Doctor. Here are the symptoms: Google, Bing, Yahoo!, etc redirect whenever I click on search results in IE (not in Opera or FireFox); Malewarebytes, Windows Defender, SUPERAntiSpyware, and Sypbot S&D will not scan (they install but the programs crash right after scan begins); HiJackThis will not operate; Windows Update for the most part fails to install updates (except I was able to download and install IE8); Avira and Spyware Doctor both are able to scan but neither are detecting whatever the issue is; and nothing nefarious seems to be running when I look at task manager. Any ideas about what I can do? Again, thanks in advance!
