Hi, I suggest you switch to Comodo or ZoneAlarm for your firewall. And also use WinPatrol. While Comodo will bug you very frequently about alerts without defining them, Zonealarm will tell you what exactly is happening. I switched from COMODO (ranked highest) to ZoneAlarm (Second most powerful). Now I know when my ISP tries to use my computer as a router AND I BLOCKED THAT. I won't recommend Comodo unless you have good knowledge of different ports on computer.. 2303, 25, 198, and so on. (NOT LPT, COM, and USB). ZoneAlarm may tell you what the traffic is. Even I was puzzled as why somebody would try to continuously access my computer. But when I am using ZoneAlarm, I came to know that these IPs were of the Reliance Communications, whose wireless I use. It showed that a packet originating from of the ISP's address, meant for another computer, was being routed through mine. Comodo and other firewalls seldom give you all these details. Coming to Winpatrol, it is a software that tracks each and every changes on your computer. For instance, if any program tries to change your home page or settings related to Automatic Updates, it alerts you before allowing the change. I have been using it since an year and have recommended it to many. It will also help you find out if there is any malware on your system. On the final note, I wud say that it is not a good idea to have Windows Firewall "ON" when you are using a third party firewall. It may create conflicts that may cause programs from responding and may lead to unexpected behavior on other applications.

These days, Windows Updates are also creating computer problems as I found them to install trackback applets (equivalent to Trojans). Check this out this article. Please let me know if you find the information useful. -- Best Regards, DreamsCentral Twitter: @DreamsCentral Signed: Monday, November 30, 2009, 1:27:02 PM IST
