I've been looking for info on that file, and for the life of me, I can't find anything that says that it's bad, even though it's marked as something to get rid of in some cases.
Yeah, hopefully someone will know. I haven't ever personally seen this file. It seems to show up in a LOT of log files when people do scans. There's just nothing saying that it's bad or harmful.
For now i'd just leave it as it is, as it really doesn't seem to be a problem at this point.
I have a file (BOOTSECT.BAK) that showed up out of nowhere at some point and i've read conflicting things about what to do with it. It's supposedly a backup file from a previous OS(even though this is a full version, clean install of Vista). I can't get a straight answer on my file either so I haven't touched it. Better safe that sorry I guess.
