im not sure what ur isp is or the hackers isp is since static ip addresses dont mean ****... the only thing u can do is install a firewall for which only does lil protection that ive found or u can reset ur ip addy to a new one to stop the hack attempts unless ur on dial up then ur ip changes everytime u sign online but if not then u seriously need to change ur ip addy and change it often if ur on a lan connection... i dont think backing up ur files will help since the hacker already knows ur system, whats on it, ur security flaws, open backdoors, and much more... if u want u can always start a brand new installation of windows or whatever u use to work on a computer and online... the only true thing that can help is find urself some programs called ip spoofers... they work the best and can hind ur ip addy that nothing else can... if u ever come across a program called an ip-redirector, download it right away and use it everytime ur online... ive been using it for over 2 yrs now and havent had any problems with hackers or destructive hackers ever since i found the program and been using since...
