Hello everyone! Thought I'd share this bad experience of mine with a security firewall which I have used for such a long period of time without any issues whatsoever. And it was also a piece of software which I always have praised for its effectiveness and toughness. Yesterday, I decided to finally downgrade to Windows 7 from 8.1 for some software compatibility issues (360 IS is incompatible with Update 1). After installing all the drivers and necessary software, it was time for me to install Windows Updates. It searched for like 144 Updates, and then began the updating process. After all the Updates were downloaded, it started the installation process, but after some time, I figured out instantly that something was wrong and the installation was taking way too long. The CF was blocking some process/service which was the root cause of all evil. I had to manually tell CF to trust the file and let it run with full authority, but the pop-up kept coming up from time to time which was weird given the fact that I already had given the nod to trust it. But still, I gave it more than enough time to complete and went to sleep. After I woke up early in the morning, I got stunned to see that the installation process was still stuck at "installing update 22/144," and the same process/service was being blocked/sandboxed by CF over and over again which didn't let the task complete. Now, what I still fail to understand is, that how come a top firewall like Comodo act so dumb or stupid that it's not even recognizing Microsoft's legit files anymore? Fair enough, if the files are unknown, then it must block or sandbox them immediately. But it should never ever be interfering with Windows Updates in the first place. This is really so disappointing. It wasted so much of my precious time and crippled my system to the point where I had to do a clean install again today. Now, I'll never ever be using it again in the near future or at all. Because to me, CF has become a pretty dumb piece of software.
