So, I've got a client who can't open Internet Explorer after upgrading from IE6. The symptoms are hard to diagnose as there is no error message that pops-up nor are there any error messages in the event viewer. When trying to open Internet Explorer, it just momentarily opens then crashes, all while leaving no error report or background process running.
Here's what I've tried to resolve the issue:
- Checked for Windows updates, none were available.
- Re-install IE7
- Re-install IE8
- Tried opening IE in safe mode, but to no avail.
- Scanned for maleware using Malwarebytes and SuperAntiSpyware and found one infection (Trojan.Agent/Gen-Sefnit). Removed the infection, rebooted the machine, but that did not resolve the issue.
- Cleared browser history and cache using CCleaner.
- Deleted temp files.
So any suggestions would be great!
