What is AutoFAT.exe? Is it Safe or a Virus? How to remove or fix it (1)

Is AutoFAT.exe safe, or is it a virus or malware?

The first thing that will help you determine if a particular file is a legitimate Windows process or a virus, is the location of the executable itself. For example, a process like AutoFAT.exe should run from C:\Program Files\Diskeeper Corporation\Diskeeper\Diskeeper.exe and not elsewhere.

To confirm, open the Task Manager, go to View -> Select Columns and select "Image Path Name" to add a location column to your Task Manager. If you find a suspicious directory here, it may be a good idea to investigate this process further.

Another tool that can sometimes help you detect bad processes is Microsoft's Process Explorer. Start the program (it does not require installation) and activate "Check Legends" under Options. Now go to View -> Select Columns and add "Verified Signer" as one of the columns.

If the "Verified Signer" status of a process is listed as "Unable to Verify", you should take a moment look at the process. Not all good Windows processes have a Verified Signature label, but neither do any of the bad ones.

The most important facts about AutoFAT.exe:
