I have recently "found" my "Event Log" and have been checking it regulary since.
What I see is that I have multiple varnings, since some days back I have had some 10 varnings which says:

"Name resolution for the [SEE ADDRESSES BELOW] timed out after none of the configured DNS servers responded."

And some of the addresses have been the following:

35.77.209.64.in-addr.arpa
56.216.172.69.in-addr.arpa
102.199.117.74.in-addr.arpa
26.77.209.64.in-addr.arpa
154.104.73.76.in-addr.arpa
254.39.23.4.in-addr.arpa
liveupdate.symantecliveupdate.com
ast.amazonaws.com

I started another thread which gave some information: http://www.bleepingcomputer.com/forums/topic441643.html

I use a Linksys router and a modem.
What could I do to check if this isnt malicious/virus/spyware/rootkit?

Thanks in advance!
