Extract text from Kaspersky quarantine files (KLQ)
To convert KLQ quarantine files to another format, you need Kaspersky Anti-Virus or other System software.
To convert other file formats to the "Antivirus Quarantine File" file type, you need software like Kaspersky Anti-Virus or a similar tool.
.KLQ files are encrypted quarantine containers created by Kaspersky security software. They securely isolate malware or suspicious data detected during a system scan.
The only official way to manage these files is through Kaspersky Anti-Virus or Kaspersky Internet Security.
Users often encounter .KLQ files when trying to recover a falsely flagged document or program. However, this format is highly restrictive. The major disadvantage of the .KLQ format is that it is proprietary and intentionally encrypted to prevent malicious payloads from executing. You cannot simply rename the extension or open it in standard applications.
Because of this strict security encryption, there are no standard conversion targets for .KLQ files. To recover the original data, you must use the Kaspersky interface to restore the file to its native format (such as EXE or DOCX). Attempting manual extraction is dangerous and can compromise your system.
This is a closed, proprietary format designed exclusively for threat containment. Standard online converters fail to process it because the internal data is deliberately obfuscated. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your KLQ file, detects the exact format, and lets you read the text inside.
If you want to convert KLQ file to BASE64, HEX, BIN, ENC, CRYPT, AES, DES, RSA, PGP, GPG, ASC or KEY, you can use Kaspersky Anti-Virus or similar software from the "Malware Quarantine Storage" category. In the File menu, look for Save As… or Export….
To convert CER, BIN, PEM, DER, KEY, P7S, PFX, ENC, P12, BASE64, P7B or HEX files to KLQ, try Kaspersky Anti-Virus or another comparable tool in the "Malware Quarantine Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our KLQ converter.
