Just tried to download 4.721 and it was infected with a trojan. Thought it might be an error, so I went back to try again and they already had the link redirected. Pretty good set of guys over there.
yea, are you sure you were at REAPER | Audio Production Without Limits, those guys know their way around the Internet. I really have a hard time thinking they would not be fully guarded. I bet you clicked on a link that was not Cockos.
Nope, followed the link from inside Reaper. Rescanned the file before deleting, and then could not get the download to work again. Assumed they'd pulled it down. Haven't tried again, yet.
Just did, and it's working fine. Don't know about false positives. Possible. Probably missed a packet and made it look like something it wasn't. Anything's possible in binary...
