Buzzing Noise With Windows Defender

[rak sa_ngop]

I have recently started running Windows Defender (beta 2) daily on a full system scan. After about 20 mins scanning I hear a 1 - 2 sec buzzing sound from the main PC unit (like a door buzzer) followed by a shorter buzz about 2 or 3 minutes later. I am pretty sure it is Defender related as when I ran the scan one hour later, the buzzing also occurred about 1 hour later.

The buzzing did not occur with the quick scan option which I was running before. Any ideas if this is a problem, (it certainly gives me a start when I hear it).

Thanks

Any chance it could just be the heads of your HD doing seeks at a high rate due to the scan? I mean, very intensive disk access can produce buzzer-like sounds.

The full scan in Windows Defender really causes very intensive disk access.

Thanks, it sounds pretty likely that your explanation is correct. I assume that no damage will occur unless it were to continue for long time (just have to change my door buzzer for a bell!!!)
