Avast cause failures in diagnostic tests--Linear read and SMART short self test?

My Dell diagnostic tests show failures. I am wondering if this is because Avast is blocking the tests.

It fails two tests: Linear read and SMART short self test.

Could these be because Avast is turned on?

And how do I turn Avast off???

Thanks Gary

Right click the avast ball and disable shields.

You could migrate to Hard Disk Sentinel (http://www.hdsentinel.com/) which is immune to AV actions. OK, immune to v7.0.1506 actions. ;D

It has the advantage that it can be run as a service under Windows, dunno about Linux.
