Don't Download Malware

Where are you getting the download?

There are malicious people who download valid copies of a popular download, modify the file with malicious software, and then upload the file with the same name. Make sure you are downloading from the developer's web page or a reputable company.

Cancel or deny any automatic download

Some sites may automatically try start a download or give the appearance that something needs to be installed or updated before the site or video can be seen. Never accept or install anything from any site unless you know what is downloading.

Avoid advertisements on download pages

To help make money and pay for the bandwidth costs of supplying free the software, the final download page may have ads. Watch out for anything that looks like advertisements on the download page. Many advertisers try to trick viewers into clicking an ad with phrases like "Download Now", "Start Download", or "Continue" and that ad may open a separate download.
