An Antivirus program performs two primary
functions. The first would be to scan all files, according to individual
preference, and identify the virus based on matching definitions in its
database. This is referred to as virus dictionary or database approach of
viruses. Secondly, if operate in real time, it attempts to identify and
questionable activities occurring in the system, which might be triggered by
other computer applications in the operating system. This is referred to as
suspicious behavior approach. These two functions are the basis on which most
antivirus applications programs are constructed.
When the antivirus Identifies a virus that
matches any definition or code in its own database, it will alert the user, and
the user has the choice of repairing, quarantining, deleting or analyzing the
infected file. If the virus cannot be eliminated from the infected file, it is
usually set to quarantine. However, users also have the choice of deleting the
document thereby eliminating any additional threats, or before the virus may
execute itself. The infected file may also be transmitted to the software
company for evaluation and inclusion in the database, or when the antivirus has
the attribute, the user may assess the infected file itself.
Since New viruses are made everyday, the
virus database of this antivirus has to be upgraded continually. Virtually all
database updates are free and they may be scheduled or performed manually.
There Is no effort to identify known
viruses here like in the dictionary approach. Every action and behavior in the
machine is tracked here by the anti virus. Therefore, this approach may protect
from new viruses which hasn't yet been identified from suspicion. However, this
approach has mostly been abandoned by many antivirus companies because of its
inclination to sound a lot of false positives. And now, there are many
non-malicious apps which could alter other executable files in disregard to the
false positive issue. This technique has become almost obsolete.
