I had an issue with my IE 9 browser. Eveytime I try to download plug-ins or even open pdf documents it keeps on crashing.
I was able to resolve the issue by doing the following:
1. Open event viewer > application log and get the error event. In cmy case the event log was Event 1000:
Faulting application name: iexplore.exe, version: 9.0.8112.16421, time stamp: 0x4d76255d
Faulting module name: bhoclass.dll, version: 18.104.22.168, time stamp: 0x4f79fd40
Exception code: 0xc0000005
Fault offset: 0x000055e6
Faulting process id: 0x3dc
Faulting application start time: 0x01cd3c79c9855c17
Faulting application path: C:\Program Files (x86)\Internet Explorer\iexplore.exe
Faulting module path: C:\ProgramData\Codecv\bhoclass.dll
Report Id: 076e16d1-a86d-11e1-9764-0024e83aa075
2. Focused on the Faulting module path: C:\ProgramData\Codecv\bhoclass.dll and made sure bhoclass.dll is not a melicious code (which was not).
3. Went to add/remove program and found Codecv installed. Removed Codecv and that fixed the issue.
I would also recommend to get a good malware applicaiton to scan the machine.
