This happens always when i download an ISO file.
Also *.ISO files downloading with bitorent (utorrent) produces CPU spikes as described in many topics here. Disabling the P2P shield helps with utorrent, but that is IMHO not a solution and why is this happening only with *.ISO files?

My configuration: AMD Athon XP 2000+, 512 MB RAM, NVIDIA MX440, Windows XP SP2, Comodo firewal active (latest version), Teatimer active, almost 11 GB of swap/temp space on C drive.

PS1: Sorry for my bad english…

PS2: Thank you for this great product!

You can safely ignore these warnings. We’ll see if there anything we can do about them.
