Tracking cookies...?

Question

I keep getting tracking cookies but I don't know where from.

I find them and delete them, but then they are there again. I can tell they have been deleted because my computer speeds up.

But I haven't downloaded anything recently, so what other ways are there for them to find their way on to my computer?

Answer 1

Pretty much every single website on the internet uses tracking cookies to track which links you have clicked on (which is what makes the links turn purple). They are not dangerous and an application called CCleaner is free and will remove all of those for you.  

Answer 2

I wouldn't worry about cookies at all, they are there to help and deleting them will in no way speed up your computer.
