NIS 18.6 Full reputation scan crashed

Hi everyone,
on my win 7 32bit pc with NIS 18.6 Italian during a full reputation scan, at 6% ccsvchst.exe crashed. SYMHTML.DLL was the module who generated the crash. NIS event log show an error code 8504,104 0x80004005 version 18.6.29.

Now I have rebooted and runned One click support. Everything seems ok. I am safe?

Thanks in advance for replies.
