Hello, i had the same problem with Avast and google since 4 days.
When I went on a website or something else, avast was freaking out and sent me same alert but with an other Malware website wich was Connexion blocked with the website ''Incduring .com''
because this one was infected by ''Script:SNH-gen[Trj]
After that i cleared my google and I uninstalled it, and cleared all the extension. Now its look like to be fixed but is my computer/google safe even though I dont have this kind of alert ?
Thanks and have a nice day.
