Our clean-ups are being done by technicians who will go over the whole fileserver and database and change every access-code and key. This is the only way to make sure that the site will not get reinfected and don't have droppers/backdoors installed.
Simple sites usually take up to 4 hours to clean up the file server, database and to update all the software on-site, while more complex sites might take up to 8 hours.
Also, Patchstack has a great add-on to avoid the situation that you need to pay extra for the cleanup. We offer a malware removal guarantee which costs $3.49 month/site which means we do the malware removal for free to your protected sites in case it will be hacked for any reason.
