compressed files

verification - or if the archive file has been exposed to potential

<br>
<a name="scan_inside_archive_files"></a>PeaZip meets this
security requirement integrating antivirus /
antimalware scan option
both from the filesystem (scan uncompressed files or entire archive
files before browsing them) and for files inside archives, allowing to
scan
selected compressed (zip, 7z, rar, or in any other read supported
format) files before extraction with anti-virus and
anti-malware software.<br>

line of defense for detecting those incoming threats.</span></td>

As role of thumb,
anyway, before any other action
you are adviced to:<br>
<ul>
<li>trust only downloads and attachments from secure,
reputable, trusted (and verifiable) sources</li>
<li>verify that the data <a

in order, to guarantee the intended content was actually downloaded,
and that no data corruption or forgery happened neither on the data

<span style="font-weight: bold;">How to scan archives for
viruses from PeaZip</span><br>
<a name="scan_rar_zip_content_with_antivirus"></a>PeaZip's
"Open with" menu, auto
configure itself to show option to analyze archive files (or analyze
compressed files inside archives) with
detected antivirus / antimalware software. The menu is also available
from Run with buttom in File Tools tool bar.<br>
This funtion is <span style="font-weight: bold;">available also
inside archives, </span>as <span style="font-weight: bold;">"Extract
and open with"</span> and alternatively as <span
style="font-weight: bold;">"Preview with" </span>which keeps the
output in a temporary work folder PeaZip will take care to clean up.<br>
<span style="font-weight: bold;">This allows to inspect
content of archives which the antivirus software itslef is not able to
access, either because encrypted or because compressed in a format the
antivirus software does not support.</span><br>
