Can't open .exe files in Vista

Pooh BearMay 17, 2011

Vista Home Premium

I was working on cleaning off a trojan (vista defender 2011) and I think I got some of it cleaned up, but when I went to open Internet Explorer, it asked me what program I want to use to open it with. Since it was just a shortcut, I chose IE. Still no go. I used another computer to download SuperAntiSpyware and MBAM. I placed them on a flash drive and copied them to the desktop of the Vista computer. Same problem when I click on them to install them. It asked me what program do I want to use to open this file.

I tried booting to last known good configuration. No help.

I am completely at a loss at this point.

Thanks in advance for any help you can give.

You may have a borken EXE file association problem, probably from the Malware. The computer should be taken to a malware removal forum for further analysis. Broken EXE associations will show up in more thorough scans used by those forums. In the mean time here's a link for fixing the EXE association issue in Vista. You may need to download it onto a flash drive, just click the EXE in the box provided on the web page the link below takes you to...

Good luck.

Yes that fake vista rogue is hitting seen it a few times now, definitely suggest going to LzD and starting a thread there of your own they will help you run those specialized scans to get the rest of that thing off there.

That took care of the exe problem and now programs open just fine. I installed SAS and MBAM and both scans seem to have taken care of the problem. Now I have another problem.

When I turn on the computer I get this error message at startup:

I also get that message if I try to open Windows Defender from Control Panel.
Any ideas on how to resolve this.

Thanks so much for your help.

Web of Trust flagged that site before it could load.

I disabled Defender in msconfig and now I don't get the error.
Probably not a permanent solution but works for now.
