I keep getting files called sqmnoopt00.sqm to sqmnoopt19.sqm in my c: drive, everytime I delete them they just return after boot, they are hidden files and i've scanned them with around 10 virus scanners but they are all clean. I've looked on google but I can't find anything about them, anyone know what they are for?
They are a part of Windows Live Messenger. Nothing to be alarmed about, unless you happen not to have Windows Live Messenger installed, in which case, I don't know.
