AVG Ultimate can not launch

Hi Zsolt,

We are sorry to hear this. Let us work together and fix this.
Run AVG clear followed by remover tool as mentioned in this https://goo.gl/JDK1db article to remove AVG traces.
NOTE: If there are no AVG program found, click on "Run Anyway" to proceed with the removal.
To install AVG Ultimate, refer this https://goo.gl/PJt6En article.
Keep us informed about the status.

AVG Ultimate can not launch with an 0xc00000005 error. I have tried to reinstall it but the new install file also has the same problem. I have tried to remove it but the remover also stops with the following errors:  0xc06d007e and 0x0000000076F9DDC2.

I am using Win 10 x64.

The Application could not run when I run the AVG Clean with the same error.
