This is followed by a second box headed "CTF Loader has encountered a problem and needs to close. We are sorry for the inconvenience."
These keep popping up each time I open something new, even a new window for explorer.
I've also now had a file "Bleh.exe" start appearing on my desktop.
I've run Panda Activescan, AVG and Spybot S&D (which keeps picking up bloodhound.pack even after it's been fixed) and after running them, and cleaning up anything found, I still have the problems.
What can I do that's not too complicated?
