Can´t open ramdomly URLs from time to time!

Hi Michael,
I have checked the details It seems that you are facing issues with opening the URL in your PC. In this case Please try to repair the AVG from control panel and also try to reset the browser.
To repair the AVG please follow start->control panel->Programs->select AVG product and then repair it.
After this process if you face any issues please feel free to contact us.
Thank you.
