Runddl32.exe detected as threat - Logs attached - PART 1

Viruses and worms
1

As soon as I start Internet Explorer Avast detects rundll32.exe as a threat. And then the message keeps popping up periodically.

I’ve ran an Avast boot time scan, AvastMBR, Malware Bytes, and OTL and the probelm still persists.

Please help me remove this. Thanks.

malwarebytes was not updated when you did the scan. Database version: 7477 latest is 7791…well maybe it was…i see the scan is dated yesterday

have you tested the rundll32.exe file at www.virustotal.com

OK nothing jumps out at me there so lets look at the drivers

OK I think I have found it now - something new

Run OTL

[*]Under the Custom Scans/Fixes box at the bottom, paste in the following
