Changing antiviruses won't eliminate the problem completely, because each of their traffic scanners flags different strings of text. An AV that doesn't flag stratum+tcp might flag a github repository of mining software or anything looking like a bitcoin address.
What good is flagging text anyway? I don't see the point in having a traffic scanner mark bits of text as dangerous, and if it wants to mark a URL as dangerous it can just use its internal firewall.
@mikeywith If Kaspersky blocked this thread too because it contained that stratum text in it, that would be ironic considering it's blocking a topic called "Kaspersky blocks access to certain topics on Bitcointalk.org"
A good example is Sophos is still running ads about their AV that none of their clients got any ransomware attacks, when just three years ago, one of them, the NHS, was hit by WannaCry. I think they have come to realize there is little they can do about destructive malware and their revenue is drying up as people realize that AVs are of little help, so they resorted to becoming deceptive and misleading people to think that their AV protects you completely. Not to mention the entire security market profits off of the existence of malware, and if all malware suddenly disappears overnight (hopefully...), all these security companies will become redundant and out of business.
That's why you hear a lot of clamor on the news about non-destructive what they call "threats" like cryptominers and cracked software because it's easy for them to block access to those. As for news about viruses and ransomware then they have more of a gloomy tone to them.
