Term Definition
Quarantine
The isolation of files that are suspected of containing a virus, spam, suspicious content, or PUPs. Quarantined files cannot be opened or executed.
Quick response (QR) code
A two-dimensional code that can be scanned with a QR barcode reader or a camera-enabled smartphone with QR reader software. Once a QR code is scanned, it can direct a user to just about anything: a web page, call a phone number, or an SMS text message. QR codes provide organizations with a quick and easy way to direct their customers to online content. QR codes are often found in magazines, product packaging, on advertisements, online, and in other marketing collateral.
