No that’s the thing, when I tried to fix my avada problem on my personal site that has Avada and put the Avada GD child theme and compatibility plugin on my site that alert would show up when I tried to access MY site and the same thing would happen if I accessed it using another computer. And when I talked to my hosting service, sure enough, there were a lot of files in my themes folder that were suspicious.
So I’m pretty sure the Avada Child theme and the compatibility problem plugin caused the issue. When Google scanned my website yesterday before I uploaded the child theme and compatibility plugin, they said my site had no security issue (see the attached image).
So I am very nervous to try out the solution you provided on my client because I think it caused my personal site to get malware. Is there any alternative solution?
