Hello. Forced again to heave up this question, because a problem did not decide. I use the antivirus of Microsoft Security Essentials, all works fine. After setting of Prevx, periodically there is a problem, namely: in what that moment during work in the internet, my web server a browser on a minute stops to answer, after it a report appears about that the antivirus of Microsoft Security Essentials does not watch at the computer, that defence is a power-off and it is suggested to include it.Prevx works fine and no problems. But this problem arises up for me only when work in a copula exactly two these programs. One by one, these programs work blamelessly. How to find a decision? Thank you.
