So I have a major virus that won't allow me to use any program on my computer without an error message stating that file .exe application can't be opened and asking me if I would like to purchase antispyware software. Also I randomly get an error message stating My computer is infected by a virus would i like to block the virus and use protection. When I answer yet to the software my internet explorer window opens with the option to purchase the spyware. I also get random pop us of *censored* and porn advertisments. I really need some step by step help if somebody would be kind enough to help me. I have a Dell Inspiron 1501 with Windows Vista O.S. I appreciate anyone taking the time out of their night to help me.
