so i clicked a link today and it made all of my currently open internet explorer windows slow to a halt, and for some reason microsoft office came up starting to install something, but i think i was able to cancel it in time. after it was all over there was an icon on my desktop that said something like WIN_SOMETHING, so i jsut deleted it.
so now for some reason nothing will play in iTunes, and a lot of pages won't load in IE. I downloaded AVG, but when i try to click the icon to install it, nothing happens at all. I bought mcafee virus scanner, and it just gets like half-way through the installation and just disappears.
so, what can i do?
