Avast Premier update interfering with internet connection.

Hey, I don’t know if I am in the right place but I decided to update the antivirus. I done it by going into the application and then settings. I updated both the virus definitions and the antivirus program. Unfortunately this morning I have had to uninstall avast due to it interfering with my internet connection. This annoys me because I like using Avast, so much that I bought the premium version for full benefits. I hope that I can download a version of Avast that is not as up to date so I can keep my computer safe and continue too browse the internet. I also hope that there will be a fix for this as I believe it shouldn’t intervene with connecting to a router and then the internet. Any tips and advice on what to do would be greatly appreciated.

Thanks, Jonathon

Do you have any other security programs installed?

Scoll down to Farbar Recovery Scan Tool and attach the two diagnostic logs
