Two anti-virus on your computer, why is it a bad idea

Some people worry about the security of their computers and personal information, come to a decision, you should install two antivirus on one computer or, more precisely, to install more than one anti-virus.

They believe that if one antivirus misses any threat, the second-then certainly from it protects. Is it really?

Of course, no antivirus software is not foolproof protection against viruses, leakage of personal information and other threats. But installing two antivirus programs on one computer - this is a very bad idea.

Practice shows that this approach to protecting your computer does not work. And it's not a competition, as it may seem too many, and the incompatibility of anti-virus programs.

On the same computer "does not get along" several antivirus, even if they are designed by one firm. They will interfere with each other, conflict, and the computer will hang or stop working altogether.

The reason lies in the fact that any antivirus tries to control all the processes on the computer. Antivirus analyzes and monitors many operations: reading and writing files, analysis of system processes, work with memory, network traffic, and so on.

Therefore, if the computer has two or more anti-virus, they will try to take complete control of an affected system, interfering with each other. As a result, the computer starts to hang out, and system resources are too small for normal functioning of any application.

In addition, each of the anti-viruses may well try to block some of the files of another, defining them as potentially dangerous. This is not competition program developers. From the point of view of protection of any antivirus do a lot of suspicious transactions.

As you can see, on the same computer, you can install two anti-viruses, but, alas, it does not increase the level of protection and may even harm your computer. If you suspect that your antivirus overlooked malicious file and the system is already infected, it is best to go the other way.
