Hi ive been having connection problems lately so looking through router settings (virgin superhub 2 ) i noticed port scans in firewall log http://postimg.org/image/gjcz2spqn .I googled ip's and port numbers and im not sure these are good (bit of a noob).Am i being hacked ? i always keep win7 and avast up to date so my question is should i be worried about these or take any measures.Any help or advise would be appreciated thanks.
