A. Proactive scanning uses intelligent methods to check all executable files, library files 
and driver files for suspicious programs.  For example, a signed file (ie. signed by Verisign)
is always whitelisted by the proactive engine. 

eScan maintains its own whitelisted database (which is regularly auto-updated, along with the 
anti-virus signatures) in order to keep false positives to a minimum. When a false positive is identified, 
MicroWorld updates its database as soon as possible, in order to increase the effectiveness and reliability 
of proactive scanning. 

Note: Proactive scanning is not 100% perfect – for this reason, it is always recommended that it be 
used in conjunction with a malware scanner such as is included in eScan.
