The .gzquar file extension is used for a proprietary file format that was developed by Softwin. These GZQUAR files are also known as BitDefender quarantine files, and are generated by the BitDefender Antivirus software, which was also created by Softwin. A .gzquar file is a possibly malicious file that has been quarantined by the BitDefender Antivirus program, which is a system security tool for Windows platforms.When the BitDefender Antivirus software detects possibly malicious code in a file, this program replaces the original file extension of the potentially dangerous file with the GZQUAR file extension. This is in order to prevent the user from accidentally activating the file, which may be a virus, a worm, a spyware program, a Trojan or a malicious application.It's best to leave these .gzquar files alone. In case the BitDefender Antivirus has erroneously flagged a valid file, then the user may remove the false positive from the quarantine list. This will revert the file to its original file format. Before doing this or before opening the file, users are however advised to make sure that the file is indeed a valid file and not a malicious application.
Unfortunately we have not received enough suggestions for software that can open GZQUAR files yet.
File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the GZQUAR file format or software that uses files with the GZQUAR suffix, please do get in touch - we would love hearing from you.
