Performance is terrible, HD spins like mad

Hi,

 

Since a few weeks my machine suddenly starts running slow.

It takes ages for an action to complete.

 

I checked with Process Monitor from SysInternals and i looks like these files are constantly being accessed:
C:\Program Files\Common Files\Symantec Shared\SPBBC\LOGS\SPPolicy.log
C:\Program Files\Common Files\Symantec Shared\SPBBC\LOGS\BBNotify.log

 

The Cpu usage is around 2%, memory usage is ok, but the HD light is constantly on and access to those files seems like the problem.

Disabling the Virus Scanner doesn't help. :-/

 

Any ideas?

 

Thanks,

Nick
