The hoster sent a list of supposedly infected files. Can phpexcel contain a virus?

Question

PHP

The hoster sent me this: "pay attention to the supposedly infected scripts, the list of which is located in the list.txt file in the root directory of the account."
The PHPExcel library got there. Has anyone already dealt with this? How can I do better?
Overwrite the whole class? Or is it a false alarm?

Answer 1

As a rule, during infection, it is clear that someone has been digging into the file. This will either be a block separate from the main code, or the entire file will be "as if from an asshole", i.e. driven through the coalifier. In any case, if this is a third-party library, then just reupload everything. And ideally, if all this is uploaded through composer .
