Antivirus Problems
Antivirus is a common product that has long been promoted as a standard commodity similar to a toothbrush, detergent or car. Antiviruses, despite their popularity, are not without flaws.
It’s simply not possible for antivirus programs to keep pace with the number and diversity of new malware being created every day. It is an arms race, and is far from all antivirus programs available off the shelf or online actually offer an overall security level that is close to 100%.
Another problem is that Trojans and viruses can alter your computer’s software in a way that it is unable to detect them. This could be because the virus alters the settings of your antivirus program or because it’s able to create false positives by utilizing one of its own functions or features.
There are a variety of instances where the antivirus program fails to detect files, even if they are dangerous. The antivirus software hasn’t yet had a chance of adding the file to its database. In order to do that it must examine the file and compare its content with known malware-related files in the antivirus’s database. This is a lengthy and resource-intensive process. The more time it takes is, the less accurate the detection. Besides, the antivirus must install an interceptor of system events inside the protected computer kernel to analyse the data and send it to its engine to be analyzed.
