There are "flash" bugs on both myspace and jango..
Flash is the code adobe uses to compress video for web use, and exploiters have been using it to "hide" code that executes on your machine when it "opens" the flash presentation.
An interesting point about the more recent bugs... they install a small program on your computer that then starts to build a bigger program using code hidden on the internet in the names of other files.
i.e. if you had the bug then goto Jango and see a pic with the name:

The green digits are code it can translate and add to its program.
So first you get the small, inoffensive bug, and then you spend weeks unknowingly allowing it to build a bigger bug in the back of your computer.
These almost always contain "Root Kits" which means they are cleverly hidden from sight, and often record your keystrokes for occasional transmission to another site that scans for bank account, SS#, CC# ect.
This is how they keep getting everyone's email address and passwords, then taking over your hotmail or myspace to additionally try to infect your friends.
1) Keep your Adobe Flash fully updated.

2) Keep an Antivirus active and updated on your computer.

3) Turn OFF System Restore... I personally recommend backing up your files regularly and reinstalling Windows over System Restore in case of "emergency".
