At least one of the viruses you mention is a not actually a virus.
According to McAfee Virus Scan JDBGMGR.EXE is just hoax. Unless you are
programming in Java it wouldn't cause any problems to remove the file you
mention but it is not a virus. For more information see:
I couldn't find any information about JDBG.EXE but I'd be careful about
removing it until you find out more.
