the internet works on my pc and i normally use Firefox, but it does this in explorer too: I open my browser, start doing whatever i want, after about 8 seconds of doing something, the browser freezes for about 3-4 seconds, then starts up where i left off. It keeps doing this no matter what i'm doing online. As you can imagine this can be very annoying when i'm typing something- it stops in the middle of the word- and i mess up because i can't see what i'm typing. It's not just when i type either, when it's loading a page, it'll stop for 4 seconds, then keep loading it. what is wrong with it? is it a virus?
