Guys,I think I have found one Culprit. Its Bit Comet. however, Bitcomet is not the only culprit. Yesterday i did a test. I restarted my machine, logged on to internet and monitered Zone Alarm with no appliactions running. At that time the rate of intrusions was around 1 intrusion per 30-45 Sec (Ideally it should have been 0). Then I gradually started applications like messengers, browsers did some surfing etc. the rate was same.Then I started bit comet and intrusions went to their peak i.e. around 2 intrusions per Second. The strange thing in this is the intrusions did not drop even after closing Bit Comet. So now can anyone comment on this, keeping in mind that Bit comet is not the only cause, but a major factor for the intrusions. As stated above that even with no applications running intrusions are happening but with a low rate.Thx in AdvanceAmit
