Hi,

The anti-rootkit will pick up some odd files, the general rule is if you know its malicious remove it, if not, submit the %temp%\samples.sar to Sophos Labs and we will tell you if it is malicious.

The temp internet files detections are generally nothing.

Also yes, closing all apps and not doing anything when the scan is running is a good idea :)
