Possible virus?

[SpacePirate]

Ok, this all started when I downloaded the hats add-on by MasterLegoDude. No I am not saying that it was from that add-on I am just telling that this is when it all happened. So I was building a house in RTB and then it happened. almost all the documents opened up in the program files, the internet, and the Email thing. And it always happens every like, 2 minutes. Plus some pop up keeps asking me to upgrade to Out-look express 0.8. I have no idea whats happening. Help D:

Your brother has been download gay donkey research.

Tell him to stop, reformat your computer and install Windows again.

Make sure to make a list of your programs that you need.
Firefox
Blockland
Winamp
etc

Or...you could use an antivirus program, then run CCleaner.

Reformat is a little too early to call.

Ok but will it happen again? Is it a virus that will come back?
Oh great. Now it just turned on F lock.

Saying from past experience, generally when a virus/Trojan starts opening windows on its own, you need to reformat. I haven't been able to remove those from my mom's computer and just had to reimage it. Best thing to do is reformat and then before doing anything, install all windows updates, and then install some anti virus program (avast is free).

Edit: But of course still try scanning with antivirus software before reformating.
