Antivirus is a popular product that has been marketed as a regular item similar to a toothbrush, detergent or car. However, even though they are widely used are not without faults.
It’s not feasible for antivirus programs to keep pace with the volume and variety of new malware being created every day. It’s an arms race, and it is far from the majority of antivirus programs available on the internet actually offer an amount of security that is close to 100 percent.
Another issue is that viruses and Trojans are able to manipulate the software on your system, making it so that it is unable to recognize them properly. This is possible when the virus alters 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 software does not recognize files even when they are clearly infected with malware. This is because the antivirus has not had a chance to add the specific file to its database. 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 long and resource-intensive process. And the more slow it is it is, the less accurate the detection. Additionally, the antivirus must install filters for system events inside the computer kernel to analyse the data before passing it to its engine to be analyzed.
