I added the FRST.txt to your last post as it's easier to read this way.
Let's see if we can get rid of the software conflicts first and possibly get the system to boot up normally.
The uninstall parts should be able to be completed in Safe Mode.
It is not recommend that you have more than one anti virus product installed and running on your computer at a time. The reason for this is that if both products have their automatic (Real-Time) protection switched on, then those products which do not encrypt the virus strings within them can cause other anti virus products to cause "false alarms". It can also lead to a clash as both products fight for access to files which are opened again this is the resident/automatic protection. In general terms, the two programs may conflict and cause:
1) False Alarms: When the anti virus software tells you that your PC has a virus when it actually doesn't.
2) System Performance Problems: Your system may lock up due to both products attempting to access the same file at the same time.
Having 3 AV programs running is a recipe for disaster!
Because of the conflicts i recommend removing all 3 programs for now.
We're not sure if any have become corrupted.
Please boot into Safe Mode and remove the following:
COMODO Internet Security
I also recommend removing:
The home website doesn't get a very good WOT rating and the program is advert supported.
It's not something i'd want on my system.
After removing these programs, see if the system will boot normally.
Let me know if you encounter any problems.
