.vir Files

I've been running NS for several years now, but somehow in the course of renewing my subscription(which has been several months ago) some of my personal photos had a .vir attached to them. The odd thing is it isn't all of my photos, but it is mainly all photos in a particular file. I don't know if I hit a wrong button during a scan or what but I'm afraid I have lost these photos forever. I have highlighted and scanned an individual photo with the .vir attachment and it shows "no security risk detected". I guess my question is, is there any way to clean or restore these files. There are literally hundreds. Any help or advice would be greatly appreciated! TIA!
