Methods of Protection Against Computer Viruses.| Free Antivirus

To effectively fight viruses, it is necessary to have an understanding of the "habits" of viruses and navigate the methods of countering viruses. If a virus entered a computer together with one of the programs or with a document file, then after a while other programs or files on this computer will be infected.

If the computer is connected to a local or global network, the virus can spread further to other computers. In the last article, I gave a detailed classification of computer viruses. That is why today I will tell you about all the ways to protect against them.

To protect against viruses, you can use:

preventive measures to reduce the likelihood of contracting the virus;

specialized programs for virus protection.

The main sources of virus penetration are communication networks and removable media.

To exclude the penetration of viruses through the communication network, it is necessary to carry out automatic input control of all data arriving over the network, which is performed by a firewall (firewall) that accepts packets from the network only from reliable sources, it is recommended to check all e-mail for viruses, and mail received from unknown sources, delete without reading.

Antivirus protection tools

The main means of protecting information is backing up the most valuable data. In case of loss of information, hard drives are reformatted and prepared for new use. On a "blank" formatted disk, install all the necessary software, which is also taken from the distribution media. Computer recovery is completed by restoring the data taken from the backup media.

Antivirus programs and hardware protection tools are auxiliary means of information protection. So, for example, a simple disconnection of the jumper on the motherboard will prevent the erasing of the flash memory chip (flash BIOS), no matter who tries to do it: a computer virus, an intruder, or a careless user.

Antivirus classification

The detectors search for computer viruses in memory and, if detected, inform the user about it.

Auditors perform much more complex steps to detect viruses. They remember the initial state of programs, directories, system areas and periodically compare them with the current values. When changing the monitored parameters, the auditors inform the user about it.

Anti-virus is a reliable and popular domestic free antivirus program. It has an effective heuristic analyzer that allows detecting unknown viruses with a high degree of probability.

The new Proactive Protection component blocks any automatic modification of critical system objects, allowing users to control access to certain Windows objects, various applications and services, providing proactive protection against malware.
