restore files question and AVERT question

i scanned my com and got this
McAfee AVERT Stinger Version 2.3.0.0

C:\_RESTORE\TEMP\A0031233.CPY

Found the IRC-Sdbot trojan !!!

C:\_RESTORE\TEMP\A0031233.CPY could not be repaired.

C:\_RESTORE\TEMP\A0031236.CPY

Found the W32/Sdbot.worm.gen.i virus !!!

C:\_RESTORE\TEMP\A0031236.CPY could not be repaired.

i have 1.8 gigs in restore/temp......can i just delete the
contests of that folder? my com freezes when i try to open
the thing

also can i update AVERT?
tehre seems to be no updaet system and it only has 44
listed viruses/trojans/etc.

im also using the avg free antivirus software(poor college
student here) and the thing keeps poping up when theres a
new 'thing' detected and ask if i wanna stop acess or
heal....when i press heal....the next time i continue it
happens again....and i cant find that file! any comments?

3 question i hope are answered.....tq 4 u time

(win me, IE 6, updated on all software etc etc)
