actually, i have a problem. i have an asus kj501 laptop running vista home premium. some hackers at some point got to my machine & now they are able to access it anytime i turn it on, even though i do not use it online. i recently installed a new hard drive, reinstalling the operating system. however, once the machine was operational, (not online) there they were, taking control of my machine & stopping me from doing any work. this has been going on for some time and i don't understand how such access is possible. If there are any suggestions i am willing to try them to solve this problem
