What are Quarantined Files?

In an attempt to rid the computer of infections, anti-spyware/anti-virus applications often place a file in quarantine. What exactly does this mean and what should you do with these files?

Quarantined files are created by anti-spyware/anti-virus applications when they scan the computer for malware infections. These applications search for undesirable applications such as adware, spyware, and viruses. Once they discover these infections, the anti-spyware/anti-virus applications attempt to remove them. In some cases, the computer’s files cannot be completely cleaned of the infection and the files are quarantined.

Quarantined files are set aside and removed from the daily functioning processes of a computer. They are encrypted so that they cannot be accessed or pose any threat to the computer’s system. It’s as though these files are in limbo or suspended in time since they cannot be activated, viewed, or used in any manner.

Quarantined files can remain on a computer forever or they can be deleted from the computer. Most anti-spyware/anti-virus applications provide a prompt that asks the computer user if they wish to delete the quarantined files. In general, it is perfectly safe to do so since the files are usually not needed for the day-to-day functioning of the computer.

The best rule-of-thumb to use when deciding whether or not to delete the quarantined files on your computer is to gauge the functioning of the computer since the files have been quarantined. If you aren’t experiencing any problems with performance, then it is a safe bet that these quarantined files can safely be deleted without expectation of any undesirable ramifications.

Quarantined files are permanently deleted from the hard drive once you choose to remove them. If you accidentally delete a system file that you later discover to be necessary, you can simply download a clean file from the installation CD for your computer. If you prefer, you can allow quarantined files to remain on your computer if you are unsure what to do with them. However, quarantined files are generally unnecessary files that you can safely delete.

The latest Malware variants now include replicating viruses. Replication occurs each time a computer boots up and each time removal is attempted. Sophisticated Antivirus and Antispyware solutions are required in order to deal with this evolving and persistent type of threat.
