#4019 - Virus Scan False Positives (#4129)

**Acceptance Criteria**
- [X] Investigate pdfs failing virus scanning and fix
- [X] Try to update clamav to the most updated version (nice to have)

**Notes**
MaxFiles 100 was causing issue with file being not scanned and using
ClamAV virus Database bank to not scan file.

`
MaxFiles in ClamAV's configuration refers to the maximum number of files
to be scanned within an archive, document, or any other container file.
Here's a detailed explanation:
For example:
If scanning a ZIP file containing 15,000 files with MaxFiles 10000:
Only the first 10,000 files will be scanned
The remaining 5,000 files will be skipped
If AlertExceedsMax is enabled, it will trigger a
"Heuristics.Limits.Exceeded.MaxFiles" alert
`
