Anti virus thrashing my hard drive

Hi George,

Thanks

I've used the paid version of AVG anti virus for about two years now, and since October last year I've noticed that periodically AVG will start scanning all the files in my windows and programme files folders.  I haven't asked it to do this, and I'm sure it's the resident shield that's causing it.   I reported this last October, and I was told that the product I had was 'Very Buggy'  and was given a free version of the 2014 product.  This has started doing the same thing now.  I'm worried that it's going to cause damage to my hard drive.  I've tried getting in touch with AVG directly, but I've had no reply, and their telepone number just rings and rings.    If this question doesn't give me any answers, I'm chaning to Kaspersky.  Please help me out here.
