scheduled scan crasching

Everyday at 24:00/12:00 the antivirus updates, and then it will scan.
About 1 min, all crasches but the scanner is still loading up.

I can do nothing. And my music stopping to play. And i need to restart from the computer button.

Os: Windows Xp sp3 pro 32bit.

Will it be possible for you to check after reinstalling the latest version of CIS 3.9 ?
