Hi malko,
I am interested in knowing what other security applications you were running. From experiences of several friends I am persuaded that it is necessary to run an anti-malware application such as Malwarebytes alongside of the AV.
Rogues seem to bypass some good AVs, and the additional layer of MBAM or something similar adds to the security.
I always have MBAM running in real time. My normal security is an AV suite, MBAM, and Win Patrol.
Recently I ran Avast 5 Pro with Online Armor free.
Tests show that Avast is a top tier AV, but none is 100%. That is not much consolation when one is infected, however.
Regards,
Jerry
