Antivirus is a common product that has long been advertised as a common product, similar to a toothbrush, detergent or car. But, despite being a regular product, antiviruses are no longer without flaws and problems.
It’s impossible for antivirus programs to keep up with the sheer quantity and variety of new malware constantly being created. It’s an arms race and far from all antivirus programs available off the shelf or online, they actually provide an amount of security that is close to 100%.
Another problem is that viruses and Trojans are able to alter the software running on your computer, causing it to is unable to recognize them properly. This can happen because the virus alters the settings for your antivirus or because it is able to create a false positive through exploiting one of its own functions or features.
There are numerous instances where the antivirus software fails to detect files, even if they are dangerous. This is because the antivirus hasn’t had a chance to add the file to its database yet. To achieve this, it has to look over the file and examine its contents against malicious files already present in the database of the antivirus. This is a lengthy and resource-intensive process. And the more slow it is more prone to error, the less accurate the detection. The antivirus also needs to install interceptors that study events in the computer’s kernel order to relay the information to its engine.
