Antivirus is a well-known product that has been promoted as a standard product similar to toothbrush, detergent, or car. Yet, despite being an ordinary product it isn’t without flaws or problems.

Antivirus programs can’t keep up with the diversity and variety of new malwares that are developed every day. It’s an arms race and there are many antivirus programs available on the market or available online offers security that is near 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 changes the settings of the antivirus program or when it exploits one of its features or functions to create false-positive.

Additionally, there are numerous cases when the antivirus software does not recognize files even though they are dangerous. This is because the antivirus hasn’t had the chance to add the specific file to its database yet. To do this, it must look over the file and compare its content with malicious files already present in the database of the antivirus. This is a lengthy and resource-intensive process. And the slower it is more prone to error, the less accurate the detection. In addition, the antivirus has to install interceptors of system events deep inside the computer kernel in order to analyze the data and then send it to its engine for analysis.
