I used CIS for years and now I have a strange net blocking. My winchester ran down, I changed and installed Win7 64 bit. I installed CIS 6.3 and if I turn on my computer the internet (cabel) can’t connect. If I turn off the Comodo’s firewall it can do. It makes no difference to Enable/disable automatic detection of private network but if I connect with turned off firewall and I enable/disable automatic detection of private network there is internet but several minutes later disconnect.
