AV check at boot

after installing Avast has done a check at reboot ,and found 2 virus identified as Win32… …updater (Trj) in C:\System volume informations.…that I removed. ;D
Before I used Norton AV 2003 always updated…(yearly fee…) and made a check every week,without find anything wrong…
Where do I find the record of this check? In the “Registry record” I didn’t find anything about…
Tks.
