I'm sorry if I put this thread in the wrong place...I wasn't exactly sure where to put this.
I think I have a virus but I can't find it.
When I am viewing a website sometimes a small video appears on the right bottom side of my screen and sometimes when I click on a link to view another site or page a pop up comes up with usually the same website but every so often it is different.
I was going to just re-install Windows 8.1 but I don't have a hard copy since it was already on the computer when I received it, Windows tech support told me they couldn't send me one and I have been trying to get a hold of my school's tech support for help since I got the computer through them but I can't get anywhere with them.
I went to Fry's Electronics and one of their employees told me to buy Kaspersky PURE 3.0 Total Security and that would fix it but it's either not working or I have done something wrong.
What can I do????
