Hi there. Do you see the marks between the sentences in my post? They're called punctuation, and they help people know what the hell you're trying to say.
Moving on.
A "Trojan" virus is named that for a specific reason; It gets in, and waits around for a while before actually doing anything, much like the story of the Trojan Horse. You weren't "hacked", you were the victim of malicious software.
The "IRQL_NOT_LESS_OR_EQUAL" bluescreen is usually caused by memory corruption; This could be from a bad driver, a virus messing with system calls incorrectly, or even just overheated RAM or northbridge. Since you mentioned both AVG and Windows Defender in your post, and you said that Windows Defender popped up, I would check AVG and make sure it's actually working. Windows Defender sucks, and is (on average) a week behind AVG in detecting new virusses. You shouldn't be running 2 active scanners at the same time, it's possible that your bluescreen was caused by anti-virus competition for system resources.
Your best bet in this case is to reformat the entire hard drive and start from scratch. The virus could have hidden inside any EXE file and be laying dormant until you run that file.
Also, as mentioned before, learn to type.
