Internet Explorer keeps opening

[scottish]

winlogin.exe is a legit program, part of windows and necessary by windows (can be infected though)
csrss.exe is a legit program, again part of OS for client/server run time (can be infected though)
atieclxx.exe is a legit program, it's owned by AMD and part of AMD/ATI drivers (think it's toshiba laptops for the graphics card) can be disabled but yeah no need.

Well whatever the cause turns out to be, I'd refrain from doing any online banking or shopping.
