However, when that fails, you can manually import that signing certificate.
</p><p>I found these steps in a post on the Kaspersky forums last Summer. The actual path on disk may vary depending on your product:
</p>
<hr>
<p>Open Firefox's Certificate Manager:
</p><p>"3-bar" menu button (or Tools menu) &gt; Options &gt; Advanced &gt; Certificates mini-tab &gt; View Certificates button
</p><p>In the Certificate Manager dialog, click the "Authorities" mini-tab (not the Servers mini-tab)
</p><p><em>If you see an existing "Kaspersky Anti-Virus Personal Root Certificate"</em>
</p><p><em>Select it and Click "Delete or Distrust"</em>
</p><p>Now click "Import..."
</p><p>Proceed to "C:\ProgramData\Kaspersky Lab\AVP15.0.1\Data\Cert\"
</p><p>Select "(fake)Kaspersky Anti-Virus Personal Root Certificate.cer" and Open!
</p>

<p>Does that work on your Firefox? If so, could you update the information, especially the folder on disk and name of the file (the last two steps)? Thanks.
