Very suspicious security history

Recently, I suffered a malware/trojan attack on my computer. I ran a full scan and managed to delete some trojans. I then ran a system restore to a previous save point ( does this help at all?)

 

Anyways, I've been noticing now suspicious activity for the last couple of hours such as: "protecting your connection to a newly detected network on adaptor microsoft teredo tunneling" <ip address> or "                         on microsoft ISATAP adaptar #3"<ip address>

 

and also " an intrusion attempt by <ip address> was blocked". I've checked my full history and have not seen this sort of "microsoft teredo tunneling" or "microsoft isatap adapter #3" security mention at all until recently after the trojans/malware. Should I be concerned?

 

EDIT: I've also down a little googling, and though I admit I have a lack of knowledge concerning these things, it seems that teredo is related to peer to peer network sharing. Again, I'm not pretending to know something I obviously don't, but perhaps this could be a backdoor entry for some hacker to gain access to my files?
