एंटीवायरस सॉफ़्टवेयर क्वारंटाइन वायरस उन्हें हटाने के बजाय क्यों करता है?

Why does antivirus software quarantine viruses and malware instead of completely deleting them? I think it would be better to make sure your computer is safe by completely getting rid of them. How can I manually remove quarantined items?

Antimalware applications provide a quarantine option, which is often on by default for two reasons:

1. Keeping a backup of the items identified as threatening in case of a false positive. Although not very common, I have seen cases of false positives on many different legitimate application files and drivers.
2. Having the items in quarantine may allow for them to be better (further) investigated. The fact that a particular virus or malware matches a known signature does not mean that it is exactly the same, but may actually have other unique characteristics.

If a virus or malware has embedded itself into a file you actually want, such as a Word document or similar, then outright deletion may be the worst option from the user’s perspective. Quarantine at least gives you a chance, however risky, to get the actual file contents you need back.
