I went to download Stream Transport and found the site blocked by Malwarebytes Anti-Malware's IP Protection feature. It claimed it was protecting me from malicious IP 126.96.36.199. This apparently is the IP for Stream Transport; my guess is that it shares this IP number with some unsavory sites. In the past, when questions have been raised in the Malwarebytes forum about seemingly innocent sites being blocked, the answer has been that if a site shares an IP address with malicious sites, there's nothing to prevent the malicious site from doing its evil on your computer when you seek to go to the innocent site, since the site is reached by IP number, not domain name.
I turned off Malwarebytes' IP protection to go to the site, downloaded Stream Transport, installed it, turned IP Protection back on, and tried to use Stream Transport, but again Malwarebytes blocked it. So unless I'm willing to trust that IP number enough to put it on Malwarebytes' Ignore List, I won't be able to use Stream Transport. Does anyone have any further information or advice about this?
