Virus monitors the program AVG

Yes. AVG Anti-Virus does not react at all to this. Module "AVG Scanning Core Module - Server Part" busily copying the system drive, all files in a row. This filling system disk completely. There is (there) permission for this action some unknown account.   This until now I have not happened. This explicit control my computer from the outside through your antivirus.

Hello Serge,
Could you please provide me with the screenshot of the exact issue so that we could assist you better in resolving the issue?
Thank you.

Yesterday, faced with the phenomenon. Module "AVG Scanning Core Module - Server Part" copies the files on the system drive on behalf of an unknown account. At the same time on the system disk fills all available space. It seems AUG program came under control of an unknown (at least to me) virus.   Stop it, I could only one way. Who knows what it is?

I was able to stop this self-damaging action. Unfortunately I did not make screenshots, as the system disk was filled very quickly, and we had to quickly search for a solution out of the problem.   Maybe I'm not exactly express thoughts in English. Then ask me leading questions.

Yes, we are glad too that we confirmed the exact issue for you.
I can understand your concern but ususally the cache file size will be of a KB and only there is amount of cache files are stored altogether it end up in huge file size. Right now we are working on this issue and once we find the fix for it we will consider about storage space and other configuration regarding this. Thank you for sharing this idea to us.

Hello Serge,
Could you please let us know whether you have received any popup from the AVG program regarding the issue and also let us know whether you have installed WebTuneUp program on your PC?
Thank you.

I am glad that finally we understand each other. I must say that the size of the cache had very big and reaches too (I have) about 100 gigabytes (!). This is quite unacceptable! Naturally, I delete the cache, only the time it takes a great deal. Can you make manual configuration of this function (the cache size, storage space, etc.)?

Hello Serge,

Do you mean that after installing AVG web tuneup you got a message that your are running with low disk space and the popup from AVG program doesn't appear at all?
