hdwwizb.exe ?

I tried Malwarebytes, but it's a stupid program. When it was finished, and I removed what it found, it made my computer restart. I was in the middle of something. I looked but I didn't see anything about an option to restart the computer or not.

hi.........Files Infected:
C:\Users\Spottedfeather\AppData\Local\Temp\trc3ns.exe (Virus.Agent)

be glad that mbam removed this nasty residing in temp file....and certain infections require a reboot to be completely resolved....

I have to agree with Jaycee about it being a hidden malware of some type since no search engine can produce results with the "b" letter added into the file name. Besides Malwarebytes there are alternative removers as well as removal tools unless you simply delete the file once located manually.

AVG should have provided the location in the alert on it. "b.exe" is malware when found. One free tool won't require you to remove AVG since that alerted you to this. The VIPRE Rescue Program is a stand alone type scanner/remover that simply unpacks and runs from a temp folder for serious infections.

When comparing Malwarebytes to Spyware Terminator some time back the ST program located and removed data miners not even seen by the other. Free spyware removal and spyware protection - Spyware Terminator

Previously that had been run along with AVG and the IE security bar until going with a newer software found more effective. Since you are running AVG already having the toolbar option enabled will alert you to bad sites to keep things off while the need for a good firewall would also be a help.
