Avast interrupting Internet Connection and then dying?
« on: January 19, 2017, 01:41:09 AM »
Hi!

I have been having intermittent problems with my internet connection on my computer dropping out (on my ASUS win 7 pro laptop) while all other devices remain connected just fine. I switched off the option for my computer to power manage the network adapter and i thought that fixed it but the problem has come back

Subsequently, I tried something that I had neglected before, I switched off my avast premier av and after this the internet reconnected straight away - what does this mean?

also once the internet reconnected Avast itself seemed to have completely stopped responding, it no longer could be accessed at all, no matter what I clicked on to reopen it, it would not even bring up the right click menu in the toolbar, yet its icon was still there - I find this concerning, naturally I did a restart once more so now I am back online and with avast going so it seems,

how do I get to the root of the problem here, what is causing avast to interrupt my internet connection and then itself stop working? am I under attack?

Thanks i will try the clean install option because i did the previous option and the problem has not gone away

something strange too is that the problem will only happen once in a day and usually when i go to my outlook.com account in my firefox browser, and at some point when i am there whether in trying to delete spam, or send a reply or other usual things, the connection drops. - i tried just turning off avasts firewall and going with the windows one, but the problem did not go away. Only when i disabled all m avast shields did my internet connection come back so this is clearly an Avast problem.

of course i cannot function with no antivirus so, i try to re-enable my shields but Avast stops responding altogher, and so i have to do a restart.

please help me Avast, otherwise i will need to ultimately switch back to Nortons or someone else

I am experiencing the same exact issues after many years of using Avast. I will do as suggested and reinstall as repair didn't work for me either. But, I have to say, it shakes my faith a little in Avast Anti-virus. Any explanation for why this happened in the first place? And apparently, I've not been protected since this began, which is quite scary given what's going on in the world. I have to admit, I'm disappointed right now.

I am following this now' but it is missing some details i need - when i do the initial uninstall of avast it wants me to do a restart, well you didnt say anything about this, so i instead started the avast uninstall utility and went to safe mode, it is running the utility in safe mode now but it is taking a while - does t take a while typically? Probably like close to 10 minutes now, its still going
