Here is the list of things that happened:
Firstly i ran msconfig and uncheked comodo option , i clicked apply but a message appeared saying i need to log on with the Administrator account,then i clicked it again , it says windows will restart , i let it restart, but when it restarts , a message appears telling me to choose one of the options:
1)Normal start up.
2)Diagnostic start up
3)selective start up.
I clicked Normal start up and Diagnostic start up one by one repeating all the procedure, but both of the times comodo was still running, i decided to start up normally and not experiment any furthur , I thought it will be better to let you know first.
Also these days after closing sites like youtube and photobucket etc a message is displayed telling
The instruction 0*62304390 refered memory at 0*62304390.
The memory could not be read
Click OK to terminate the program.
Thanks a lot Fed , im waiting for help.
