CAVS weekly scan freezes on Stop .... and Def+ Predefined Policies vanished

I was running my monthly defragmentation when weekly virus scan started. It hangs on stop after i let it scan for a while ( 32000+ files scanned 0 virus detected since all the false/positives are now in my safe files list).

I hit the stop button again but than it frozes definitively.

I close CIS but it frozes badly … and the scan windows was still up.

After a reboot all Def+ Predefined Policies were gone… and CIS was asking for every single explorer.exe move.

Diagnostics of course was helpless… Everything looks fine … except the rules were empty and i was upset having no time to rebuilt them ( i had some specials blocks and netshare rules) nor reg restore solution…

Today after a full reinstall + full database download ( with reboot ) i uncheck the prebuild scheduled scans forever.

Nobody was killed except my precious time 88)
