If Antivirus Signature Detection Is Not Effective, it's Useless? Try other such as OptimoAV!

In every second, 2.3 Malware variations are being created. Now I will explain why it is difficult for signature detection to keep up with new Malware, and why you should protect your device by using signatures and antivirus software such as OptimoAV.

First of all, let’s understand what is a signature-based detection?

In the internet world, there are so many variants on Malware and so are the ways of protection against them. Signature Detection is one of the forms of defense to keep you safe from Malware.

How signature detection works?

It works by scanning the content of programs and files on a computer with the signature codes of viruses. These virus signatures are present in the library of the antivirus software.

If the signature of any virus is detected, the antivirus software will protect the PC from damage. The 

suspected files are either quarantined or encrypted in order to make them useless and inoperable.

Since 200,000 new Malware are created each day, it is very difficult for signature detection to keep up.

Why Signature detection is becoming difficult

In this section, I will explain to you why it is impossible for signature detection to keep up with the onslaught of new malware and why there is still and need to use signatures to protect your devices.

While creating these Malware signatures, the software company first does its research that the file is malicious or not. After identification, an algorithm or hash of the file is created. The Hash is a number which is used to identify the files via a string of texts. The string of text is unique for each and every file.

At first, the antivirus company tests the signature. Afterwards, it is updated in the signature dictionary. People, who design Malware, sometimes create a malware variation to get around the signature detection. This type of signature-based malware is used for investigations and forensic purposes.

Whenever you install new antivirus software, always scan the programs and files using signature detection. This helps in preventing malware from corrupting all the files and programs within the system.
