Do all downloads contain adware?

Do all cpa downloads contain adware/spyware?

I'm speaking primarily about free game downloads, PDF viewers/creators, and 7zip/winzip type of downloads?

I constantly get people telling me their anti-virus will flag these when they try to download.

This hurts my earnings significantly as most people will not download when this happens.

Pretty sure they do.

That's how they make their money. Kinda of how PPV works.

If they don't, then the pay must be even worse than what you're getting now. Even reputable programs bundle adware.
