Antivirus is a popular product that has long been promoted as a standard item similar to a toothbrush, detergent or car. However, despite being such a common product, antiviruses are no longer without flaws and problems.
It’s impossible for antivirus programs to keep up with the variety and quantity of new malware that is constantly being created. It is an arms race, and it is far from all antivirus software available online, they actually provide a security level close to 100 100%.
Another problem is that Trojans and viruses can alter the computer’s software to ensure that it can’t detect them. This can happen when a virus business security software alters the settings of the antivirus program or when it uses one of its features or functions to generate false-positive.
There are many instances when the antivirus software is unable to recognize files, even when they are harmful. This happens because the antivirus has not had the chance to add the particular file to its database yet. To accomplish this, it needs to examine the file and compare its content with malicious files already in the database of the antivirus. This is a lengthy and resource-intensive process. And the more slow it is it is, the less accurate the detection. The antivirus also needs to install interceptors that look at system events deep within the protected computer kernel in order to send the data to its engine.
