The Private Internet Access (PIA) application may sometimes trigger a false positive in antivirus software due to how it operates.
To protect your privacy and security, the PIA application creates temporary files and folders with randomized names. Some antivirus programs may interpret this behavior as similar to that of malware.
If you want to confirm that you have the official installer, you can verify the SHA-256 checksums of the installer against the values listed on the checksum page for the latest client. However, these checksums will not match if you downloaded the installer from the initial email, as those installers include your username to simplify installation.
If you want to add file exceptions for your antivirus software, please contact the PIA support team. They can provide instructions based on your operating system and antivirus software.
