Do you know that the scanner will search all files in the memory , in the boot sector , and on the disk
for code snippets that will identify the file as a virus , To
prevent the false alarms , Most scanners will check the code of a
suspected file against the virus code or the checksum of it , It is implemented in all
major anti-virus software packages ?
Everyone must know that the scanners can find the viruses that haven't executed yet , This is very important for e-mail worms which can spread themselves rapidly if not stopped .

You should know that the integrity checking is the only way to determine if the virus has damaged the file , Most integrity checkers today have the benefit of detecting other damage to the data such as the corruption , and it can restore that as well .
Everybody should know that Anti-virus software makers develop a set of rules to distinguish the viruses from non-viruses , The program or the code segment should follow these rules , So , it is marked the virus and deal with it accordingly .
You should understand that the interception software detects virus-like behavior and warns the user about it , Interception is a good method to stop logic bombs and Trojan horses , When it is not detected by scanners , The interception software will detect the destructive events caused by logic bombs and Trojan horses .

Antivirus software disadvantages
You should know that the firewall is the
program that blocks the hackers ,The viruses and the spyware from getting into your computer from the Internet , You can use the hardware like the
router to reinforce the firewall especially if you use more than one
personal computer to access the Internet , or you have a small network
of the computers .
You should know that if Anti-virus is using a string to detect the virus , all the virus writers would have to modify the string to develop the new virus , The scanning process will cause delay in the network service for the employee users .
You must know that the main problem with integrity checking is that there are not
enough companies that offer comprehensive integrity checking software , The integrity checkers will not be able to differentiate between the damage
done by the corruption and the damage done by the virus , So , giving the user
unclear information to what's going on .You should know that if Anti-virus is using a string to detect the virus , all the virus writers would have to modify the string to develop the new virus , The scanning process will cause delay in the network service for the employee users .
You must know that the virus writers can write the viruses , making the current set of virus detection rules obsolete , The interceptors aren't very good at detecting anything , It can not detect the viruses before they launch , and a lot of damage have been done because of the nature of the interceptor .
Using AVG protection for a couple of years, I'd recommend this Anti-virus to everyone.
