Please Advise

My home computer (win XP) is infected with a dnschanger. I have no internet access at home and must download/post/etc at work on a Mac G5 using Safari. Your MGTools.exe file will not download. I have searched the forum and read about others with this problem. I am logging in with the "remember me" button checked and have purged the cookies folder. When I right click on the link and use "save linked file as..." it comes up with the .php extension. My Mac will only save with a .html extenstion. Can you email me this file? Please advise so I may complete your READ & RUN ME FIRST instructions. I have been fighting this damn bug for over a week now. Thank you.
