Okay this is what happened to me. I formatted my computer, well
upgraded to Windows 7. Then I installed Fire Fox and upgraded all my
drivers and installed my virus protector ESET NOD32 Anti-virus system.
After I got all my pictures and everything I wanted to keep from what I
had before I formatted. After awhile I got onto NS on firefox and made
it my homepage. Lets make this clear. THE ONLY THING I DID WAS LOG ONTO
NS. Nothing else but the MSN homepage and Mozilla homepage to download
Fire Fox. Now while I was on NS I was just browsing the forum replying
to threads and what not and randomly I got this pop up that was
obviously an internet window that looked like a windows alert that said
my computer may be at risk and said you need to make a free virus scan
and it has an okay button or an close button that was vista style and I
don't have vista so basically it was trying to install a Trojan to my
computer and I was able to avoid such happenings but it happened 3
times and it happens at random there wasn't a certain thread I clicked
on every time or a picture or anything. And I know this did not come
from any other site because I hadn't done anything but go to those
three sites.
