I just installed Avast Free and performed a full scan. As soon as the scan was complete, I had "Error Reporting - Application Error" on screen. Click to send to Microsoft. Avast said it found 2 infections and click to reboot and run boot time scan. I clicked "Send error report to Microsoft" the error details sent, then Avast totally shut down. The computer was not froze, but it did not reboot until I rebooted it. The 2 infected files were traces of a previously removed malware that were now located in system restore. MBAM scan was performed prior, there are no current malware or rootkits.
Event viewer recorded 2 errors:
