I am running SEP ver 11.0.4000.2295.
In the main manager page (Home) I seem to be getting a number of infected files with a .qsp extension.
I have run SEP in safe and normal mode. I have run Malwarebytes, Hitman Pro and Trend Micro online scan and found nothing.
But every now and then SEP flags up this odd .qsp file and quarantines it!!!!
