I tried down loading mozilla firefox to use as a web browser. It was downloaded 100% then when prompted to "run" the error message comes up with a red cross and the message'This file is corrupted" and won't let me proceed. What do I do now?

It looks like something went wrong while it was downloading--try downloading it again and see if the second copy works. If it doesn't, try downloading it from a different browser.

This almost definitely isn't an issue with Firefox--there's either something wrong with your computer or your internet connection.

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.
You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
