When you are choosing an antivirus software for your business or home it’s important to think about more than just its detection rate in controlled tests. It is also important to ensure that it is able to detect new malware and viruses. Virus writers are constantly developing ways to thwart antivirus software. They create viruses in order to disable them, hide them from detection methods and even bypass antivirus software.
One of the initial types of antivirus softwares compared the files received by devices to their database of malware that they have identified. This is a type of signature detection and works well with older malware, but the problem is that virus creators can create new signatures for the latest types of viruses at any time and the antivirus security would always be catching up.
Modern antivirus programs employ the heuristic method to identify potential threats. Heuristics do not search for exact matches, but rather at the tendencies of incoming files and software to see whether it is compatible with malware known to exist. This technique is enhanced by behavior-based detection, which analyzes the way a program or program behaves in pop over here order to determine if it’s malicious.
Some viruses attempt to take down antivirus software by hiding, blocking access to an antivirus program’s updating system or causing corruption to code or library files required for a virus scanner to work. Certain viruses are more sophisticated, and can directly alter or disable the functions of the antivirus software. These viruses are becoming more widespread and contain features such as a worm component which can be transmitted from one computer to another.
