Ok, So i have taken many of you guys' advice and started using Comodo Firewall and MSE. However this combo is preventing me from using windows update, installing drivers from Nvidia and installing Windows Mobile Device Center. I could not update Nvidia drivers through WU. So I downloaded it directly from Nvidia and gave that a try, but still no go. Windows update will get stuck on "installing updates 1 of 1". Same goes for Windows Mobile Device Center. All of these scenario will all start install and get stuck during the process. I tried to install the new Zone Alarm firewall for W7 and it was having problem installing (getting stuck at 98%) and this was done after removal of Comodo. It eventually installed after several attempt. As of now I am using MSE + W7 firewall and everything seems to work ok. However my computer seems significantly slower after all the failed installs. Was wondering if anyone else is having these problems? Could it be Comodo problem or MSE not liking non M$ firewall or just MSE problem?
