But, to echo Draclvr, do you have an antivirus program, Laurette?
You seriously need one if you don't.
They stop Trojans from getting to you in the first place.
I'm using MS Security Essentials (free) right now and I'm happy with it so far.
Oh, yes, and Malwarebytes Pro. How could I forget that?
I took a quick look at Super Anti-spyware and I don't think it is an AV.
As always, I could easily be wrong.
