Antivirus programs additionally filter different kinds of records that can contain infections. For instance, a .compress file record may contain packed infections, or a Word archive can contain a noxious full scale. Records are examined at whatever point they’re utilized – for instance, in the event that you download an EXE document, it will be checked promptly, before you even open it.
It’s conceivable to utilize an antivirus without on-access checking, however this for the most part is anything but a smart thought – infections that misuse security openings in programs wouldn’t be gotten by the scanner. After an infection has contaminated your framework, it’s a lot harder to eliminate. (It’s likewise difficult to be certain that the malware has ever been totally eliminated.)
