Then unzip it and run it. If you still get an error, give the exact word for word message.

To run HijackThis, try renaming the hijackthis.exe file to test.exe and run test.exe. Tell me what happens now.

 

Have About:Buster do another update!

Then reboot in safe mode and delete:
C:\WINNT\localNRD.dll
C:\WINNT\system32\rbxwrfe.dll
C:\WINNT\questmod.dll
C:\Program Files\ISTbar <--- the whole directory
C:\Program Files\SideFind <--- the whole directory
C:\WINNT\system32\kmdc.dll
C:\WINNT\system32\mssaru.dll

Reboot normal and post a new HJT log. This is a start. There will be more to do. I do not believe it will fix your about:blank problem though.
