It appears you are using both AVG8 and Avast. You will be better served by removing one... I would remove AVG. Other than that, I see few alarming problems found other than the trojan, "Trojan.I.Stole.Windows" which I assume has now been removed. You have some "File Threats" which are merely cookies and junk... but really evil or problematic stuff, I do not see it.
But more importantly, we need to know what you mean by, "...there is something is wrong to my computer..." Tell us specifically what seems to be running improperly... or discuss performance now vs in the past.
It would also be helpful to have a description of your computer hardware... memory, cpu, hard drive, cooling system, and operating system... also, how long everything has been installed and when did the problems become significant.
