When
detects a file that cannot be disinfected, it sends it to quarantine.
The same occurs with suspicious files that could represent a threat to
your PC. The function of quarantine is to isolate these types of files
from your system until the solution is available.
Files are kept in a safe place with no contact
with other files on your PC, ensuring the security of your system. Files
in quarantine cannot be used. You would first have to restore them to
their original location, after checking whether they are really infected.
Every time is updated, it re-scans files in quarantine to disinfect them if possible or return them to the original location if they are innocuous.
