what does having things in quarantine do?

just wondering what the quarantine feature is used for

 

It is really not safe just to immediately delete everything that a malware scanner finds during a scan. It is much safer to quarantine items, making them harmless, until you know exactly what they are and what you should do with them. All antispyware/antimalware/antivirus programs have false positives sometimes, which are harmless softwares accidentally thought to be malware. Other times, even though an item is malware, you might want to keep it quarantined until you could submit it to Ewido for further study. Or perhaps, until you had researched the malware to be sure it is dangerous and exactly what changes it had made to your PC. Anything in quarantine is rendered disabled. After a period of time, perhaps a few days or a month, you can safely finally delete the items, once you are sure your PC is operating normally after they are removed. Quarantine is there for your added protection.
