Clean/remove infected files so website can display

My hosting company contacted me and said there might be infected files on my website. They sent this: "During a routine scan, we detected suspicious contents that suggest your 'erandall38' account has been compromised. We have temporarily suspended your website to protect your website visitors from getting impacted and also preventing the impact on your website reputation as well as our server’s reputation. We have uploaded a file '[login to view URL]' within the stats directory of your account which contains the full list of infected files. We need you to take one of two actions suggested below: Please follow the steps given below to remove the infected contents on your own: 1. Open the ‘[login to view URL]' file through your FileManager (OR use ‘FTP’ software like FileZilla). 2. Clean or remove each of the listed files. 3. You can also upload a clean copy of web files from your local backup. " I need someone that can view the files and clean/remove them without effecting my website look. Would also need them to talk with my hosting company to verify it has been done correctly and get them to put my website back up and unsuspend the account.
