Cross-site contamination can happen when a hacker gains access to one website on the shared server, and from there manages to infect other sites on the same server. Even if you clear the infection from your own site, you may be continually reinfected if the other site isn’t cleaned up. This 2015 article tells us things have improved for shared hosting, but certain hosts still don’t do enough to prevent cross-site contamination.
