hi everyone
I am having some sort of weird problems, and im not sure if it's some kind of spyware or similar, but anyway, everytime i startup my pc i get win32 error message with 2 options( send error or dont send), then i click on send error, and after that ( not directly) my desktop bar and other windows pages change to classic style, and sometimes classic combined with winxp style.

then i go to appearance and i change it back to winxp style, and goes back to normal.
and theres something else, everytime i go to activate my windows fire wall i get the following nessage"windows firewall cant be displayed. Do you want to start the ICS Service?" then i choose yes and then i get the following message" windows cannot start ICS Service" so briefly i cant access my windows fire wall.
I really dont know whats going on , and i really would like to see the solution of this.

and thanx for any help.
