A digital signature is a feature that allows you to identify the source of a program. Anything not expressly allowed will be blocked. In order for the virus to be authorized to run, it would have to obtain a valid digital signature from one of the trusted companies. It's not impossible, but it's quite difficult.

This system is hardware-isolated and protected from unauthorized access. To ensure proper isolation directly in the processor, the processor and compatible chip on motherboard. There is only one change in the warning window if the program is run without digital signature. Just like today: only extensions in the official store can be installed. There is no way around this limitation.

Can't change this setting, but companies can allow installation certain programs to install programs for domestic use. The volume of an antivirus is greatly reduced when it does not need to scan most programs.

In the end, the work was done in reverse order: instead of checking for a bad program, a list of trusted programs was created. One of them checks for "macros" in documents. "Macro" is small program, which can be inserted inside a document or sheet to make it easier to use some feature.

These macros can perform unwanted actions, and the antivirus task will check for something suspicious. It's like limiting some cards from the deck and freeing the wildcard. However, the new restrictions come at a price: the lack of freedom to create software. But the trend points towards more controlled and limited systems.

Solve the problem automatically

Perhaps this is the beginning of the “post-antivirus” era. The process of installing or uninstalling a program may fail for a number of reasons. This article describes the following issues. After all, two pairs of eyes are better than one, as the saying goes. But does this phrase apply to cybersecurity?

Firstly, several antiviruses that operate simultaneously create an inevitable conflict between system resources. The consequences are different: the system slows down, it may become completely inoperable, or the antivirus may stop working, which is dangerous. Do two antivirus devices have double protection? On the contrary, the level of security is reduced.

They thought our product was causing the problem. To solve this problem, the user has to choose only one solution and get rid of the rest. In addition, there are many cases where the antivirus thinks that the files of another antivirus are infected. This is not done on purpose; when launched, the antivirus performs many "suspicious" activities, such as application monitoring. Antivirus files are safe and all antivirus developers try to minimize false positives, but whitelists are sometimes not completely up to date.

Kaspersky Lab products are not compatible with third-party anti-virus products. The list of incompatible solutions is divided into two groups. The uninstall process will start automatically. The second part of the list shows products that our installation tools cannot uninstall on their own. Check if one of the programs in the second part of the list is installed on your computer.

If one of these programs shows up in your searches, you know what you need to do. Before installing a new antivirus, uninstall the previous antivirus using its uninstall utility. However, it may not be possible to uninstall a program that is incompatible with your antivirus due to the capabilities of your system. To manage this type of situation, each vendor offers a proprietary uninstall utility. If you know which antivirus is installed on your computer, try downloading the uninstall utility from the vendor's official website and running it.
