After a friend sent me a file, I decided to scan it as she has had malware in the past. However, when I clicked on it, instead of "Scan now" I got a "Insight Network Scan." I clicked on it and the scan proceeded as normal, finding no viruses. This has me confused. If I "select all" for all the files in the folder, including the one I was sent, and click to scan, I get the the "Scan now" option. Why the difference between the number of files? Also, what is "Insight Network Scan" and how different is it from the "Scan now" option? I'm using Norton 5.0 on Windows XP SP3.
Copied from the Help file:
The Insight Network scan uses the Cloud technology wherein a remote server on the Web contains the latest virus definitions. Norton Internet Security scans your computer for the latest security threats. When Norton Internet Security performs the Insight Network scan, it uses the virus definitions that are available locally and in the Cloud. Norton Internet Security provides additional protection by using the most recent definitions in the Cloud, apart from the definitions that are available locally on your computer.
When the Insight Protection option is turned on, Norton Internet Security performs a traditional scan and an Insight Network scan simultaneously. The traditional scan uses the definitions from the local system, and the Insight Network scan uses the definitions that are hosted in the Cloud.
Note: This Insight Network Scan command is available only for single file.
Cyberlife is absolutely correct.
However, the 1st scan you performed was on a single file and the 2nd was for a group of files. If you go with what CL said, then that should clear your doubt.
