Hey there.
I'm very sorry for taking a long while to reply to you on this problem.
I am happy to announce that somehow, the problem has been eliminated.
After removing the trojan you found, the system seems to be working fine, and boots up properly most of the time.
It was a very, very strange problem =/
Anyway, I thank you so much for your help. Couldn't have fixed it without you. God bless you.
Good luck with the Forum, and take care =)
