Should Viruses Be Deleted or Quarantined? (2024)

FAQs

Should you quarantine or delete viruses? ›

Should I remove, quarantine, or allow a threat? This depends on how much you know about the file that has been detected. Remove deletes the file from your PC. Quarantine moves the file to a safe location and blocks it so it can't run.

Some computer viruses and other unwanted software reinstall themselves after the viruses and spyware are detected and removed. Fortunately, by updating the computer and by using malicious software removal tools, you can help permanently remove unwanted software.

Removing a computer virus manually is a complex process. Viruses may install themselves in several different parts of your system. If you do not completely eliminate the program, it may also reinstall itself at the next system reboot.

The suspected malicious file is not deleted but instead moved from its original location to a safe place on your computer where it is unable to run as a program. Files in quarantine are harmless and cannot infect your computer. They can therefore be quarantined indefinitely.

The most important reason for why virus removal should be sought is that viruses are able to breach the security of one's computer. Some of the most harmful ones are even capable of disabling installed anti-virus software. As a result, a computer becomes even more vulnerable to other viruses and malware.

A quarantine is the process of isolating a file suspected of being infected with a virus to a specific area of a storage device in order to prevent it from contaminating other files.

Scan your device for malware.

Run your scan again to make sure everything is clear. If the scan shows there are no more issues, you've likely removed the malware.

The Microsoft Defender Offline scan will automatically detect and remove or quarantine malware.

By installing malware on your device, these cyber thieves can access your data and steal your personal information. Malware can allow criminals to access your passwords, location, contact list, send SMS messages without your permission, control your device, and install spyware and ransomware.

Do viruses permanently damage your computer? ›

Some advanced forms of malware can cause permanent damage to your PC, such as hardware damage, locking you out, or data loss. However, if you use a good antivirus and regularly scan Windows for errors, you can keep your system running smoothly.

Make sure you have enough available disk space

Microsoft Defender Antivirus requires disk space to remove and quarantine malware files. It might be prevented from completely removing a threat if there isn't enough available space on your PC, particularly on your system drive (usually drive C).

Files tagged for quarantine are encrypted and moved to a protected folder, preventing further execution and potential harm to the user's system. Each product has a Quarantine Manager where users can permanently delete or restore files from quarantine.

On your Windows device, open Windows Security. Select Virus & threat protection and then, under Current threats, select Protection history. If you have a list of items, you can filter on Quarantined Items.

Try to stay at home and avoid contact with other people if you or your child have symptoms and either: have a high temperature. do not feel well enough to go to work, school, childcare, or do your normal activities.

Consider staying away from people at high risk of getting very sick until: 10 days have passed since your symptoms started, 10 days have passed since you tested positive (if you never developed symptoms), or. You test negative for COVID-19 with an antigen test (such as an at-home test)

Some viruses are programmed to initiate when your computer boots up. Deleting temporary files may delete the virus. However, it is not safe to rely on this.

A: Yes, there are viruses that hide part of their code where the antivirus software can't find it, so when the mail virus gets quarantined then the hidden portion notices that the main virus is missing and will reinfect your computer.
