Having used Comodo in the past I felt secure that I have a great product and decided to install CIS onto my HP laptop with windows 8.1 installed and fully up to date. I downloaded the free version initially to see how it had changed since my last use, this is when the problems began.
My first worry was the time it took to install, 30 minutes or so. Beforehand I had disabled the network and uninstalled my old virus protection to avoid any conflicts. But this did little to help it would seem. After the install I got the little widget onscreen and went ahead and reconnected the network and let CIS update itself.
Odd thing was the touch pad stopped responding at around this time, luckily I had a mouse plugged it at the time so just used this to restart. Ouch… I rebooted only to be left not even passing the bios check! A black screen and the Caps lock light flashing with noway to shut the laptop down. I had to pull the AC cord and battery out for a few minutes for the laptop to boot back into windows!
Not greatly happy about this, but I persisted. Got to the desktop and waited, just to make sure everything was going to work ok. 10 minutes later there was no sign of CIS running in the taskbar or widget. So i went to double click the CIS shortcut and yet again the touch pad was not responding, it was at this time I realised the entire keyboard was locked out, not a single key was working!?
So I rebooted again to see if this would clear only to be hit with the same black boot screen… Pulled the supply again and got back into windows, turns out the keyboard locks out after 5 minutes. I decided it was best to uninstall CIS due to these problems, unfortunately for me this made things worse.
Once uninstalled and rebooted I was still presented with the black boot screen. Pull the supply yet again and got back to windows, 5 minutes later the keyboard still locks up, but now with the added bonus of 5 minutes later a BSOD, shutdown and black boot screen!!! And so this continued…
After sometime of working out how to get into safe mode from within windows (boot root did not work) all was once again fine. But I have had to do a “Refresh” of the system to get it back into working order.

So what on earth happened here? I had a perfectly running laptop one moment and then hours of hell trying to get it working again, which I am still doing by way of painful window updates just to get back to 8.1!? I believe I am not the only one to have suffered from this issue.
