How to fix a error downloading problem?

Hi!
I have problems with my Google Chrome. I’ve downloaded a free anti-virus from the web through Google Chrome download. After minutes of download, it’s download percentage is at 99%. But after a while it says “Network Error” then the file download interrupted and the file doesn’t download. Here’s my question, how to fix an error downloading problem on Google Chrome browser?
Thanks.
