Something very strange happening on every website i log into
 

Every time on either yahoo or other websites when i sign in it goes back to sign in page, it doesnt say i typed it in wrong either. do you think someones made a virus that can see your passwords.

Possibly a corrupt cookie. Delete all cookies, log in again and see what happens.

Ah i reduced the cookie threshold on security and it worked. I t was because i reset internet settings.:p

Thanks for your help:)
