Kempus,
There doesnt appear to be much wrong with the log, apart from geing a bit short. They are usualy a lot longer than that.
Try going to GRC.com , download and run a prog called :- Shoot the messenger.
This will stop msmessager from running and prevent most of these popups. Do not confuse this with MSn Messenger, its a totaly different thing and wont be affected. There is information on GRC.com on this subject.
Goodluck
