Need to resolve some hosting issues as sites are not showing

I have a couple of sites hosted on [login to view URL] and they are not showing. ipage sent me a mail saying it is a security issue and it could be some outdated files. I need the issue checked and resolved. The mail content given below for reference. Dear Hemangi, During a routine scan, the security team at iPage discovered infected files in your "hemangiip" account. Typically, these security vulnerabilities are due to the presence of an outdated application or script in your account. You can view a list of the infected files in the /stats directory of your account, in a file named 'websitescan.txt.' You can find more information on how to access this file, interpret its contents, and remove infected files in the article below: [login to view URL] Please make sure to check any file backup(s) you have for a clean copy of the infected files. If you have clean copies, you can upload those. If not, once you get the infected files cleaned or removed, we recommend you keep regular backups of your website going forward Finally, to learn more about how to keep your site safe, visit the article below: [login to view URL] Sincerely, The iPage Team
