Is it possible to degauss and then reformat a hard drive to resolve a virus issue?

If you are reinstalling the operating system that should be sufficient to wipe out everything on the hard drive.  The only time you may need to take more action is if you have a rootkit.

Not sure what you mean by degauss, but my typical plan of attack for a virus that my antivirus won't erase is to just reformat and perform a clean install of the operating system. Usually takes care of the problem.

Putting a drive through a bulk eraser will result in a non-functioning drive, as the portion of the drive's operating firmware that resides on the platter in modern drives will also be erased. Even older drives that only stored file structure and user data on the platters should be unusable after degaussing, since if the degauss is 100% effective, the track servo markers will be gone and the drive's control electronics will not register the presence of the platter(s).

If the pc is still bootable why not ask about virus removal in the security forum, may be possible to remove the virus and save all your stuff?

DO NOT DEGAUSS.  It will make the drive unusable.  The platters all have a clock track on them so the head can sync properly.  Degaussing will wipe that track and it a boat anchor from there.
