hi mr dj
i m gourav bansal ok
and here's answer to your questions:
there exist many antivirus which provides alert if there is goin to any unauthorized access
and you could turn your firewall on and update your windows and if still you hav any doubt that your computer is being infected by a computer then you can use with having an internet connection a command
by typing
on command prompt :netstat -a
then a list will appear then you would be able to see all of your ports open or in use then compare these ports with a list which can be easily downloaded and searched on google by typing :trojan ports list: then compare wit the list if there is a port matching with your port on your pc and in list same then your computer being infected by trojan and in other case your computer not infected by virus and if infected by virus then you can do one thing which is done by manipulating registry files then virus will be removed
thanks
