Hidden Rootkit Files... VIRUS?

thanks in advance to anyone who can give me some insight.

i've finally got my computer looking the way i want and running as fast as an atom can produce, but i've run into a problem. i recently hid a bunch of folders i never access, and subsequently ran a virus scan. none of these issues appeared before the hiding of folders and the virus type appears as, "hidden file", so i'm assuming that it's because of all this hiding i've applied to various folders. these are the errors i get when running the virus scan:

file - threat - type - risk level

GDIPFONTCAC- - hidden file - rootkit - 3/3
desktop.ini - hidden file - rootkit - 3/3
desktop.ini - hidden file - rootkit - 3/3
index.dat - hidden file - rootkit - 3/3
wpdlog00.sqm - hidden file - rootkit - 3/3
wpdlog01.sqm - hidden file - rootkit - 3/3
wpdlog02.sqm - hidden file - rootkit - 3/3
desktop.ini - hidden file - rootkit - 3/3
desktop.ini - hidden file - rootkit - 3/3
desktop.ini - hidden file - rootkit - 3/3
index.dat - hidden file - rootkit - 3/3
desktop.ini - hidden file - rootkit - 3/3
desktop.ini - hidden file - rootkit - 3/3
index.dat - hidden file - rootkit - 3/3

when i attempt to fix all errors, i run another scan and they all persist to appear as viruses. when i go to folder options and check "show hidden files" and uncheck "hide protected operating system files" i am able too see them, but the files continue to appear as viruses.

should i be concerned, or is this a non-issue which won't affect my computer?

thanks again

housecall free download from the site. its okay i did a system image restore from like 9 hours ago and all is gravy. i did some research after i posted and realized it'd be easier to just restore than go thru the trouble to get rid of the evil.

thanks anyways guys.

yeah they are. its not a system restore point. it's an old system image. thats like a reformat. it's gone trust me.
