Antivirus The first and necessary step is to install anti-virus protection and proper use of antivirus software. Without it, there is no protection and security of your computer. Do not wait when it will collapse under the pressure of a computer virus - especially if you use the internet. Installing antivirus software is simple in principle. Price is not an obstacle and can not be an excuse for his absence. Given that the majority of well-known manufacturers can find a few that provide antivirus software for home users for free.
Antivirus software regularly scans files and computer memory. And as a rule, shows the appearance of the infected files, or computer viruses and worms. Followed
by warning users and appropriate action taken in accordance with the
configuration parameters that can, for example, delete the infected
files. Ideally, the user will be warned in time, and prevent damage to the system. Just
read the instructions carefully, and do not forget to regularly update
anti-virus databases, which ensures the correct operation of antivirus
software. To make this clearer, I will compare all the "medical" example.

Antivirus software and all its actions are somewhat similar to the process of vaccination against
infectious diseases. It
would make sense to vaccinate if you vaccinated appropriate type of
vaccine, and your body produces antibodies increases immunity to most
infectious diseases. Since
it is impossible to predict all types of computer viruses that can come
into contact with you, then vaccination is against those for which
there is the greatest probability of a collision. But there is a new disease. The old vaccine were received before will not protect you from him. Security You get only when you receive new vaccines that will give you protection against new diseases. Similarly, anti-virus software can not know in advance what will be the new computer viruses and worms. Therefore, your software will help you to successfully detect all known viruses. You do not have to purchase and install a new version every time there is a new computer virus. Antivirus programs are designed so that the information about the discovery of new viruses and worms can be added later. This
is the aforementioned anti-virus database - the file containing the
information required for detecting computer worms and viruses that need
to be updated regularly. Whatever anti-virus software in their daily work have found new viruses. If
the database can not be updated regularly, antivirus quickly becomes
useless because it will not be able to cope with the new computer
viruses that appear every day. The settings may be different depending on the products you use. But basically all come down to visit the manufacturer's website and download the file to the appropriate directory. Next run the appropriate settings in the software, and then the whole process is automatic.
