i don't know much about security but i believe that my internet has been hijacked, Hotmail, Paypal, and banking sites have been replaced by fake ones (they are a jpg picture of the original site,but the only functional part is the login ) i tried using "https://" and got 404 error , im being redirected somehow, it happens on all browsers so i thought it was same sort of "man in the middle" attack someone might have intercepted my internet cable, but on my netbook i can access the original sites normally.
can anybody help me?
how can i get rid of this?
im using windows on my desktop and linux on the netbook
neither spybot nor Microsoft security essentials found anything
(sorry for my bad English im from Brasil)
