Chrome automatically blocks harmful downloads that try to cause problems on your computer, like:

• Giving you viruses
• Leaking your private data
• Changing your browser and computer settings
• Adding unwanted extensions or toolbars to your browser

Why the download was blocked

Your file download may have been blocked for one of two reasons:

• We think it might be a malicious, unwanted, or uncommon file.
  • Malicious: You tried downloading malware.
  • Unwanted: You tried downloading a deceptive piece of software. This program, disguised as a helpful download, may actually make unexpected changes to your computer.
  • Uncommon: You tried downloading an unfamiliar and potentially dangerous piece of software.
• We've found that the website you tried to download the file from has been known to distribute malware.
