Anti-malware is a type of software developed to scan, identify and eliminate malware, also known as malicious software, from an infected system or network. Malware can obtain user login data, user needs to computer to send spam, and basically give attacks a way to access to the computer and the material stored in the computer, and even the capability to check as well as control the online . What is Anti Malware? Antivirus collision is a case where a signature created for one malware file, or one malware family, triggers on the other benign files, unrelated to original files for which the signature was created. A behavioral-based anti-virus scanner tends to generate a support call if it detects an anomaly. Signature-based detection offers a number of advantages over simple file hash matching. Another serious drawback to signature-based detection is the use of compression and packing by malware authors. Signature-based security can only defend against what is already known. Cybersecurity is a continual cat-and-mouse game. If analysts only have a small set of samples or sometimes only a single sample to work from, the signatures efficacy is both limited and prone to false positives: detecting non-malicious code that may have the same attributes.
