maybe a problem avast / cis v4.1 ?

I run avast! v5 and comodo Firewall v 4.1 on my PCs under xp sp3.

Since yesterday’s last Comodo’s update (from 4.0 to 4.1), i noticed that from times to times, I cannot acces to browsing the second level of the “start menu” of windows. (pressing “start / programs” on the taskbar).

When i disable D+ → no more problem
When I disable Avast file scanner → no more problem

I know the bug must come from CIS , but I wonder if you have experienced such a problem (for those who have the same config)

oops : the problem is not with avast, it’s only cis… sorry pals !
