It detects malware based on characteristics typically used in known malware code. Heuristic-based detection is generally used together with signature-based detection. To identify viruses and other malware, the antivirus engine compares the contents of a file to its database of known malware signatures. Signature-based detection is the most common method. There are several methods antivirus engines use to identify malware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity (privacy), online banking attacks, social engineering techniques, APT and botnet DDoS attacks. While antivirus software was originally developed to detect and remove computer viruses, modern antivirus software can protect from malicious Browser Helper Objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraudtools, adware and spyware. Rosenberg, in Rugged Embedded Systems, 2017 2.4 Antivirus Systems Malware prevention solutions can prevent third-party tracking of user activity, as well as stopping unnecessary slowdowns in individual systems and servers. These solutions can provide protection by preventing e-mails that include security risks, such as phishing attempts, worms, and viruses.

However, many antivirus solutions now include antispyware functionality as well.Īntispam solutions for your e-mail gateway can do more than just reduce the amount of nuisance e-mail. Many organizations will employ virus solutions from multiple vendors as a way of strengthening their defenses further.Īntispyware solutions operate very similarly to antivirus solutions, with signature and pattern files that have to be updated regularly. By downloading the latest pattern and signature files regularly (see the section “Ongoing Maintenance” on page 221, later in this chapter), an organization can protect itself against the latest release and developments of viruses. Antivirus solutions are available for workstations, servers, e-mail gateways, and even handhelds. Jaffe, in IT Manager's Handbook (Third Edition), 2012 Malware PreventionĪntivirus software has long been a cornerstone of protecting the IT environment.
