Antivirus is a well-known product that has been promoted as a standard product, similar to a detergent, toothbrush or a car. Yet, despite being an everyday product antiviruses aren’t without flaws and problems.
It’s impossible for antivirus programs to keep pace with the volume and variety of new malware constantly being created. It’s an arms race, and it is far from all antivirus programs available off the shelf or on the internet actually offer the security level of 100 percent.
Another issue is that viruses and Trojans can alter the software running on your computer so that it cannot detect them correctly. This can happen when the virus changes the settings of the antivirus program or when it exploits one of its features or functions to create a false-positive.
There are also many instances where the antivirus program fails to detect files, even when they are infected with malware. This is because the antivirus hasn’t had the chance to add the particular file to its database. To do this, it needs to analyze the www.pceasyblog.org/how-to-stop-avast-from-blocking-websites new file and compare its content with known malicious files in the antivirus’s database. This is a long and resource-intensive process. The slower the process is, the less accurate detection. Furthermore, the antivirus needs to install interceptors of system events deep inside the protected computer kernel in order to analyze the data and then send it to its engine for analysis.
