When choosing a security software for your home or business, it’s important to consider more than just a program’s detection rate in controlled tests. You must also ensure that it is able to detect new malware and viruses. The virus writers are constantly working to develop methods of defeating antivirus software. They develop viruses that disable their own detection techniques, or get around the anti-virus software itself.
One of the earliest types of antivirus softwares compared the files received by devices to their database of known malware. This type of signature detection works well for malware that is older. However, virus creators are able to develop new signatures at any moment for new malware types.
Modern antivirus programs employ the heuristic method to identify possible threats. Heuristics are not looking for exact matches but rather analyze the underlying patterns of files and software to see whether it is compatible with malware known to exist. This technique has been augmented by a method of behavior-based detection which examines how the program or file acts to try to determine if it is malicious.
Certain viruses try to deter anti-virus programs by hiding from detection, blocking access to the antivirus program’s update system and causing corruption to library or code files that a virus scanner needs to function. Some viruses are more sophisticated and will directly alter or disable elements of the antivirus software. These viruses private equity data room are becoming more common and come with features such as the worm component, which can be transmitted from one computer to another.
