Internet Explorer/MalwareBytes Wont Open

October 27, 2011 at 11:12:20
Specs: Windows Vista SP1, Intel Core2 Quad 2.40ghz
After an attack by "Zentom System Guard", which I removed manually and also removed Trojan.Win32.Generic.pak!cobra through and Ad-Aware scan, my system is working fine except that I am unable to open Internet Explorer and other programs which access the internet, including MalwareBytes. They will not open at all - right away I get the "Internet Explorer {or MalwareByes'} has stopped working..." box.

Windows updates fail, as does upgrading IE7 to IE8. I downloaded IE8 to a disk and installed, but same problem. I tried to install Firefox from a disk and get the same issue.

I've done a system restore. I have restored all IE defaults and disabled all add-ons. I removed all BHO's through HijackThis. I've tried opening the programs in Safe Mode. Still no resolution.

Any ideas?

these 2 fully working trials seem to work really good:
1- Trojan Remover
2- Hitman Pro
Run them till they are clean and then use their own uninstallers in all programs to remove them after the cleansing

Some HELP in posting on plus free progs and instructions 7 Medals

if the previous post fails to help, perhaps run command promt with safemode, and open the mbam.exe and try scanning it that way.

Manually removing a virus from the registry can be a dangerous first step.
on another note, you may wish to run rkill first, before you manually attempt to fix.

After running Rkill, I still have the same message for IE8, but now the error I get for MalwareBytes is "This operation returned because the timeout period expired". Same error whether I'm in safe mode or trying to open from command prompt.

Just for info, MalwareBytes will run if its exe is changed to cmd or bat.
That applies to both the download and the program file (mbam.exe) itself.

Often viruses stop exe's working, which is why MalwareBytes has this facility.

Always pop back and let us know the outcome - thanks
