Period of inspections varies, we can not say when it will be verified a particular site. Therefore, data on malicious code on the site can be updated with a delay.
The site on which your hosting provider has found malicious content typically is re-scanned. But if in the course of the next test would be that the site is still infected, the intervals between rechecking will increase. The earlier site is decontaminated, the faster your hosting provider will know about it and will enable your site to reduce the dangers to users.
