After I updated Avast to the nitro update (I think this is the cause), I started to see in my router's log some strange lines like miniupnpd[a number]: discarding NAT-PMP request (too short) 0Bytes
And then another line like unknown udp packet received from "my laptop ip" and then a port
It repeats like ten times with different ports
And there is another thing
After the update, when I opened Internet Explorer it showed a pop up with sometinhg like a web program is trying to open in uprotected..
Or something like this
From avast and I pressed allow
It was the first time
Hope you can explain me what are these things
I hope you will not give me a copy paste answer with : download a program and copy a log
Because I only want to know what are these things.
