Hello Hamish,

We don't think AVG is causing this issue to the Edge browser.
We request you to disable AVG program temporarily by following the instructions mentioned in this link: http://avgread.me/1GnMD3N and check for the issue with Edge browser and do let us know the status of it.

Hi, I have AVG installed on my school computer. At home everything works well, but on the school network, any internet link produces a page saying either "There is a problem connecting securely to this website", or "There’s a problem with this website’s security certificate" - even Google! Is there anything that I could do?
Thanks

I disabled AVG at school for five minutes and was able to open links without receiving errors. The IT guys at school said something about there being a different security software on school computers (I bought this computer externally though?). Could this be messing with the program
