Antivirus has been promoted for a long time as a product like the toothbrush, detergent or automobile. Although it is an ordinary product it isn’t without flaws and problems.
Antivirus software simply cannot keep up with the variety and variety of new malwares being created every day. It is an arms race, and it is far from all antivirus programs that are available on the internet actually offer an overall security level that is close to 100 100%.
Another problem is that viruses and Trojans are able to manipulate the software on your computer, causing it to cannot detect them properly. This could be because the virus alters the settings of the antivirus program or because it is able to create a false positive by utilizing one of its own functions or features.
There are a variety of instances when the antivirus software does not recognize files even when they’re clearly harmful. The antivirus software has not yet had a chance of adding the file to its database. To accomplish this, it needs to look over the file and check its content against malicious files already in the database of the antivirus. This is a resource-intensive and lengthy process. The slower the process is, the less accurate the detection. Besides, the antivirus must install filters for system events inside the protected computer kernel in order to analyze the data and pass it to its engine for analysis.
