My computer's been acting very odd...

For idk like three days now occasionally when I open a page it redirects me to a system error page, but another tab at the same time doesn't. I'm not sure if this is me or my provider (Comcast), but it is getting annoying and if its me I'd like to fix it.

I had something similar to that at one time and it turned out to be some adware, so maybe running it through a good antivirus might get rid of it.
