Jautājums
SuperUser lasītājs Sardar_Usama vēlas uzzināt, kāpēc pretvīrusu programmatūra karantina vīrusus un ļaunprātīgu programmatūru, nevis dzēš tos ?:
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?
Kāpēc antivīrusu programmatūras karantīnas vīrusi un ļaunprātīga programmatūra, nevis tos dzēst?
Atbilde
SuperUser atbalstītāji Julie Pelletier un Mokubai ir atbilde mums. Pirmkārt, Džūlija Pelletiere:
Antimalware applications provide a quarantine option, which is often on by default for two reasons:
- 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.
- 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.
Seko atbilde no Mokubai:
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.
