From the Quarantined results window, select the files you want to delete or restore and click:. Click Delete to permanently delete the selected file s.

Automatically Delete Quarantined Files. That's why the antivirus takes infected files out of commission and leaves the deletion decision to you.
The other reason for putting files into quarantine is false alarms. Sometimes a perfectly law-abiding file looks like a virus carrier.
If it's automatically deleted, important programs could just stop working. When the antivirus puts an infected file into quarantine, it deletes the file from its original location. It's no longer there and can no longer infect your computer. Then it makes changes to the file so that it cannot run as a program, and puts it in a hidden folder that other programs cannot see or access.
It's in a hidden, high-security jail. You can simply ignore quarantined files. For most people, this is uncomfortable. However, if you're not sure how to proceed, it's a safe option while you find out more. Most modern viruses make their own files, which contain nothing but the virus waiting for an opportunity to infect your computer. If all your programs are running fine, and your system isn't crashing, you can happily delete those files. You may find files in quarantine that surprise you: files that have been on your computer a long time, or files that a program needs in order to run.
These may be the victims of a false alarm. Depending on the software, you can choose between a basic scan or a full scan. The difference usually has to do with the depth and breadth of the scan. With a basic scan, it may only scan major files to save time, while a deeper scan will usually take longer as it scans every file on your computer. If an infected file is found, it may be sent automatically to quarantine or you may be given a prompt to decide what to do with the infected files.
It depends on the antivirus you use, and your software settings. When an antivirus places an infected file in quarantine, it deletes the file from its original location and makes changes to it so that it cannot run as a program.
It then transfers it to a hidden folder that other programs or yourself as the user cannot access where it stays until you choose to deal with it. Quarantined files are not deleted unless you want them to be. As mentioned above, quarantining a suspicious file merely relocates the infected file into a safe space on your computer.
You will need to instruct your antivirus to delete the file or otherwise delete it yourself manually. You can keep a file in quarantine indefinitely, but if an important file that is infected, you should place it in quarantine and clean it.
While quarantining a virus is safe and the best course of action for infected files, there is always the risk of your antivirus making a false alert and quarantining a system file that your computer needs to run effectively. Which is why the deleting process is usually left to your discretion. Quarantined files cannot harm your computer but they do still take up valuable space on your hard drive. Therefore, if you have infected files in quarantine, you should clean them as soon as possible.
Not all antivirus programs will be able to detect all threats. Full system scans will uncover more infected files than basic antivirus scans , simply because more files are being scanned.
