AtomicParsley NOT working! (GitHub/wez version is downloaded, but, AV says It's Dangerous!!)

Greetings! I think, Google makes pictures in its new picture format, WebP'; you are experts and up to date in programming, can do, such as "Any other Pic. format to .jpg" and using it with AtomicParsley to do its "Artpork". It may be a bleek idea, but, ... worth a try! No hard feelings!!
ATB! Rgds,

should be same as #25687 and #25717
