Malware Virus deleting and Server/Hoster transfer

Hello,

I need an expert for removing them and than transfer clean to a new hoster.

And i have much more projects in future, so im searching for a longterm partner.

All projects are in Wordpress and one is with custom plugings.

and on one domain its a google malware warning and cannot enter the page!! this need to fix asap too!
