Whenever I turn on my avast vpn I can use the internet as normal for a while, however after an hour or two my connection suddenly gets throttled hard and the internet refuses to load, even though it does say I'm connected to the internet(and running troubleshoot doesn't solve anything/doesn't find a problem). That's obviously a problem in itself, however interestingly this problem persists even after I turn the vpn off. The only way to fix this insane throttling of my internet is to restart my laptop. Is there a fix for this? Or should I get a refund?
