Have you been burned by a fake "compressed" download before? Let us know in the comments so we can help others avoid the same mistake.
Even the most aggressive compression algorithms (like 7-Zip on Ultra settings) can only shrink a file by about 30-40% before it breaks. That would get you to roughly 2.5GB—not 100MB.
You are looking at a scam. You will either waste hours downloading a broken file or spend days cleaning a virus off your computer. The only person who gets "highly compressed" in this scenario is your bank account if they steal your data.
