I have COMODO firewall, and since last night the programs ielowutil.exe, msfeedssync.exe, and when I tried to open it just now Windows Media Player, have been frequently trying to obtain shutdown privilege. Comodo has caught it each time, but it has never happened before and /certainly/ does not seem like something that should be happening at random. This seems to be coinciding with problems I've been having connecting to the internet--Sunday it would not connect at all and would give a loud, odd tone as it tried to connect (I have dial-up) while yesterday it worked. To-day again I had problems connecting but eventually it /did/ connect. I have a Toshiba Satellite A215 laptop running Windows Vista. Monday night I installed IObit Security 360 and it found more than one Rogue.Errorfix and an Adware.MWS. I do not know what those are but I had it remove them. My other security programs are AVG, Microsoft Security Essentials, Comodo Firewall, Spybot Search and Destroy, a daily sweep using IObit's Advance SystemCare, and an occasional scan by TrendMicro Housecall. AVG seems to only be good for cookie-finding. MSSE has found and blocked a trojan but has done nothing else. I'm not sure but I can try to provide additional information if it's needed.
