Is this really a malware problem?

[badcomputer]

Hello,

I recently used malwarebtyes to scan my computer. It found two threats called Heuristics.Reserved.Word.Expliot. I then uploaded these two files to virus total and it came up clean. It is also located in my system32 files. Any help would be greatly appreciated.

Thanks for the prompt reply!

Reserved word exploit definitions mean there should be no other files named explorer.exe in that directory. You have what looks like backup copies of the files.

I recommend you do the following:

1. submit the detected filename to www.virustotal.com

2. submit the normal file without the .bkpcpy to make sure it was replaced also.
