It’s no news that no antivirus is 100% safe.

It has always been that way and will always be. The answer is simple: there are actually very few antiviruses sharing the biggest market share (the top 5 AVs most likely represent more than 95% of the installed base). So the virus writters can very quickly check their “lastest,not-released-in-the-wild-yet” virus and see which antivirus applications detect it as a malware and modify it accordingly.
