4.8 Virus scan/ cpu shutdown

[psw]

In a multi-processor system I recall the team saying that the rule would be that they would use n-1 processors for scanning (where n is the number of processors).  I am not sure if there is intended to be any self limitation on avast in scans on a uni-processor system.  Hopefully a team member will chime in.

I checked CPU load during scan on multicore Q6600 (4 cores Intel). Only 1 CPU core is used during scan. 3 other cores are idle.

I believe Vlk said that this is a plan for future versions - when the number of cores on an average computer will be > 2.
Right now, a single scan is limited to a single core (but you can run as many parallel scans as you want, of course).

Regarding the original problem - yes, if the computer really powers down, it's most likely a hardware problem (CPU, power source, ...)

Well I cleaned out fan,boards,etc. Ran another full scan and same thing happened. 95-100% cpu and shutdown after 10 or so minutes. Should I try the beta version or go back to 4.7? Any help appreciated. Thanks.

I suggest you try if the latest beta version solves this:
Download the updater (http://files.avast.com/files/beta/aswbeta.exe) and run it or go here for more information.

OK, just tried the beta version and it does the same thing. Im pulling my hair out now. Anymore ideas would greatly be appreciated. Thanks.
