Anti-virus programs: views and basic functions
To prevent a personal computer from hanginging and doing well with its main tasks, it should be protected from malicious programs. They can cause irreparable damage to the PC and disrupt its operation in general.
Virus programs get into the computer in different ways (through websites, special programs, mail and so on), and only specially designed products can handle them. If you notice that the PC began to hang, long boot and even spontaneously shut down, you need to buy windows antivirus and install the program. It identifies and deletes all viruses that are available in the system.
What is a virus?
This is a specially recorded program that automatically connects to other programs. It easily makes copies and embeds them into files, entire computer networks and system products to disrupt their work. Malicious products cause corruption of files and important documents, and also create various disturbances in the work of the computing device. Depending on which part of the computer is infected, virus programs can be network, file, and so on.
Each malicious product has its own features and deals a different level of damage to the computer. Network malware easily penetrates various computer networks. The file software is embedded in executable modules and different types of file documents. Macro are able to infect complex applications by Microsoft Office type, including their documents and files. To protect the PC from such a malicious product should buy a license anti-virus, Cenakotorogo will be a bit more expensive, but such a program can provide a computer safe operation.
The popular malicious product are Trojan programs, which are perfectly disguised as useful programs and interfere with the normal operation of the computer.
What kinds of anti-malware systems are there?
"Anti-viruses" perform many useful functions, among which are the identification, elimination and reliable protection of the PC against infection by virus systems. Today, there are many kinds of anti-virus tools that we'll talk about next.
The most reliable anti-viruses are such as Avast for Windows or Mac OS, Eset and Kaspersky. Their licensed versions can be bought at an affordable cost on the site https://altonkey.com. Before you buy a software tool to protect your PC, you should determine its functionality and type. For example, detectors find a specific type of virus in memory and file documents, and then issue a signal message. The disadvantages of such programs include the fact that they identify viruses that are known to their creators.
Vaccines and Faguy are software products that find and "treat" the device from all sorts of infections. They remove viral products by returning their original appearance to their files. First of all, Faguy detect all suspicious programs in the memory of the device and only then begin to destroy them. Given the fact that the developers of virus programs are constantly improving their products, "antivirus" for their detection and destruction need to be systematically updated. To protect your home computer, you should buy antivirus on 1 computer and install it, and then every time you turn on the program will automatically start, find viruses and eliminate them.
The most effective tools for ensuring the safe operation of PCs are the auditors, the original state of all components of the computer system (disks, catalogs, etc.) until it is infected. They act on the user's request or systematically, by comparing the current state of the computer with the source. All identified discrepancies are displayed on the screen of the computer device. The comparative characteristics of such data are taken as a basis:
- Number of files;
- Length of file documents;
- Exact date of modification.
If your "antivirus" has expired, you can always buy an extension of the anti-virus and thus provide your device with a safe operation.
Immunizatory are also residential programs that protect files from being infected by viruses. They are used if the PC does not have a doctor program that "treats" virus programs. The vaccine changes the algorithm and structure of the program without damaging the operation of the computer. In this case, the malicious product perceives the computer's disk and program as infected, so it does not touch them.
Functions that perform saz
Programs that remove all malicious files from PC memory can be used periodically or downloaded in the background. This allows them to find viruses when the computer is turned on, as well as downloading file documents and copying them from removable media. A more reliable option is to scan the PC for viruses in the background, but to do this, the device must be productive and have enough free memory. Experts advise antivirus to buy a license, because only licensed products will not harm the computer and cope with its main tasks.
Anti-viruses perform such functions:
Protection of computer system against viruses – finding and elimination of viral products that penetrate through removable and permanent carriers, as well as through websites and mail;
Permanent protection against malicious products – automatic check when the computer device is turned on;
Verification of the user's need and desire – detection and "treatment" of malicious programs of the computer as a whole or in its separate systems;
Mail Check – Analysis of incoming and outgoing messages;
Restore your PC after a virus attack that completely deletes virus programs.
