Hello, Dear Visitors of the Forum!
I have such a problem.
Half a year ago, such a virus got caught somewhere: when the computer is turned on, it regularly in about 1 hour makes a sound similar to knocking on the door. The rest of the time he does not give up.
Kaspersky does not see it, the reinstallation of the screw does not give anything.
Per there is a program that will analyze all the software that runs on the comp and will be recorded... In general, at the next manifestation, so that you can see what was loaded.
There may be other ways to solve my problem, I am happy to listen to the recommendations of specialists.

Cheatministrator: Isn’t that from the ass, by chance, the sound?

Tatra: You are absolutely right.
and 5 points.
thank you.
