No problem, so long as you have it working.
where do I go to go into safe mode
Keep tapping f8 while booting your system 
No problems here on all 5 computers.
i got same issue, at first i thought its my connection maybe…
it kind of happend after i got an
avast malware threat…
from Avast them selfs.
while i was doing playing
counterstrike
(nothing was d/l or anything)
This is an avast auto-update check in progress (the avast.setup process controls updates) and one of the download servers
Yes, this has happened before, avast has hundreds of update servers and is constantly adding them and they are on occasion reused IP addresses and it is possible that previously this IP was blocked by the network shield.
I have reported it for investigation and correction.
