CIS FW - Strange ICMP and IGMP connections!Help please!

Hello everyone,
Recently i have been getting strange Outgoing IGMP connections from system (Pic 1). I am using windows 7.My main concern is that I don't know why these exist and that there's no option on how to block them!I tried adding a rule but only TCP/UDP/ICMP/IP are available.Also i have noticed some UDP Out connections (Pic 2) .Do you guys think it's a trojan or something?

As this wasn't enough i have been getting a lot of ICMPV6 connections from programs like audiodg ,VLC,windows media player and foxit reader (pic 3). Do you think these programs are trying to update or?

Lastly, i am having svchost.exe connections from various ports (as shown in pic 1,2,4 and 5). Do you think these connections are normal? Is there any way to find out if these are good to go?

I am still a newbie in firewalls so I would really appreciate any help,thank you!

The IGMP junk is normal. Most often related to
- UPnP
- SSDP
- IGMP router discovery

Did not check the rest since ImageShack is so slow that it is unusable for me... there is an attachment feature here for a reason.

 

IGMP is multicast and the IP is only local !

should set allowed!

Foxit and icmp - dont know, i dont use Foxit since years any longer, crappy software
maybe it checks for updates or plugins... whats the endpoint ip for that ip_v6 number?
(pls ask the foxit support for further details!)

port 53 ► http://en.wikipedia.org/wiki/Domain_Name_System
(any search engine might helped you for this!)
access is needed - anyway, each program connecting to the web need port 53
to resolve domain-names to ip! web-basics!
svchost should limited on lower ports (135/137/139/445) to your lan if possible with CIS.
those ports are important for lan working computers, but not for the rest of world.

BTW the source port varies - it changes with each access to the web although the destination port may the same
