I Can't download microsoft products (like Msn)and i cant visit microsoft-based pages.

Forsaken

Hello.
My name is Kostas and i am from Greece. I admit that in my personal 2nd PC i had fake windows xp copy. And that because i used that pc only for some programs who didnt need Internet Connection.
But before weeks i had to connect that pc to internet. Almost at the same time when i update my XP"fake"Copy (what a "smart" boy you may say..) a Windows Genuine stuff appeared and a pop-up "balloon" who was saying that "My PC may have risk".
2 weeks after that my AVG started not to work properly and my Msn too..
The avg couldnt update and the msn couldnt update either and it couldnt "add" more e-mails.One more thing is that i couldnt visit Microsof-based pages (like g.live.com e.t.c.) and i still cant update avg.Likewise i cant download any of the top 20 free AntiVirus programs. I cant really open their home pages of them. (like avg.com ). Surely and other pages are "locked".
I have try some stuff and the only thing i have manage is to clear permantly from the pc the "WgaTray.exe" who was running on TaskManager and when i was deleted it,the moment after re-appeared.
Can someone please help me with this? (And surely buy an official microsoft key is not an option- Firstly cause i cant afford another official microsoft copy and surely cause i cant visit official microsoft page)

Friendly,
Kostas Forsaken. (Please forgive me for my english, I remind you that i am from greece..:D)
