Okay so my computer keeps redirecting me to sites I did not ever use... did not even know existed! So I'm wondering if there is something that will stop it. I deleted all my chrome extensions and that has reduced it, used to I had to close a porn game or a site I had no want of being in. I am not using an incognito browser so I'm afraid my school gmail account will be banned for it... I don't know what to do and I need some help!

Your computer is infected with a virus ( I assume you know that) so if you have run your virus protection and it has not found it, take it in to a shop and have them clean it for you. Since many may also find and send personal information, it is important to do it.
