I went to a web page and a window popped up in Spanish. I, being the person I am, clicked "no", but after that a fake internet explorer that is linked to what I believe is an inappropriate site, and some sort of windows movie editor plugin appeared on my desktop, start menu and documents folder.
Also, it started dialing my modem, and the only way I could get it to stop was to unplug the phone cord.
I deleted the files and the modem didn't start dialing again when I plugged the cord back in, however, when I went to turn on my computer this morning, the same thing happened again, even though I wasn't on the internet.
If you need it, I can take a picture of the desktop when the pop-up appears, but I'm not on that computer right now.
I'd download software to get rid of it, but I'm not even sure what it is, and me being the poor 38k internet person I don't have the ability to download a lot of removal software, so I have to be pretty sure of what this thing is before I go any further.
