I run 'Full System Scan' every night; most of the time it returns a result of having scanned 1.35 million objects (approx.) but sometimes it completes its task having scanned only 250,000 objects only.
Since I'm new to Norton Antivirus I have no previous knowledge of the product.
It works very well, I'm very happy that I switched over to Norton Security.
Please and thank you,
