my search engine is (was) google, but after visiting some x-rated sites my search engine has changed to golpher search. everytime i start my internet instead of google i get golpher search and also some x-rated site or a site for loans and etc. also my computer seems to take longer to do its operations. what is the name of the problem i have (virus, spyware,etc)? and how can i get google back on startup? im suppose to have a firewall, anti virus, and spyware that came with my dsl.
thank you for your help
