Troubles Opening KLQ Files

Missing Kaspersky Anti-Virus

When you double-click your KLQ file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If this is the case, it's usually due to the fact that you do not have Kaspersky Anti-Virus for %%os%% installed on your computer. The OS won't know what to do with your KLQ file, so double-clicking to load the file doesn't work.

Tip: When another KLQ application is installed, you can choose to open it by selecting "Show Apps" and using that program.

Kaspersky Anti-Virus Requires Update

Your Kaspersky Quarantine File file is incompatible with Kaspersky Anti-Virus because you might have the wrong version installed. If you do not have the proper version Kaspersky Anti-Virus (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. The primary cause of this problem is that your Kaspersky Quarantine File file was created by a different (newer) version of Kaspersky Anti-Virus than what's installed.

Tip: You can sometimes get hints about the right program version by right-clicking on the KLQ file, selecting "Properties", and looking at the version information.

Summary: In either case, the majority of problems opening KLQ files are related to not having the correct software application installed on your computer.
