Something I should note here is that prior to February 16th, I had NEVER seen ANY activity recorded in either the IM or P2P shield logs. The only thing I did yesterday (Feb 16th was to download that Secunia program and use it.
I have seen that also with Secunia PSI v 2.0.0.3003, but not with v 2.0.0.4003, which I am now running.
It seems to be related to traffic between your computer and Secunia servers, as Secunia is set to use IE for connectivity (annoying for me, as who knows when a new exploit will pop up in IE that might affect this traffic). As the point of PSI is to monitor the status of installed programs on the host system, it makes sense that there would be some
IM traffic done in this way. Secunia chose to use IE, like many vendors, and I just happen to have to run IE8, which isn't upgradable to IE9 on my system. There has been a minor vulnerability for IE8 existing for more than a year that Microsoft just seems not to have gotten around to addressing, not that I think they ever will.
Secunia Link here:
http://secunia.com/advisories/product/21625/?task=advisories_2011 is an example. See the unpatched vulnerability here:
http://secunia.com/advisories/43623/. This is not the one I'm thinking of, will have to exit user account, fire up PSI to find the more severe one, so there will be an EDIT at the bottom of the post when I find it.
Back soon.
EDIT:
My bad.
This vulnerability first reported 2/26/2007 and still not fixed. Here:
http://secunia.com/advisories/24314/This is the most severe one IE currently has.
