McAfee Virus Definitions Review

McAfee Virus Definitions

McAfee Virus Definitions can assist your computer in protecting itself against malware like viruses, spyware, worms, Trojans and adware. The software updates these definitions regularly so it remains vigilant against emerging threats.

Malware outbreaks may no longer be prevalent, yet malicious software continues to proliferate at an unprecedented pace. Recently, McAfee added its 200,000th definition and expects this number to double within two years.


McAfee Virus Definitions provide essential protection for PCs against digital threats like viruses, trojans, worms, spyware and adware. The software scans for threats before blocking or quarantining them to stop further spread. In addition, identity protection suite features include password manager, VPN connection and file shredder to safeguard private information.

McAfee Security Suite is one of the best-selling security suites, providing excellent malware detection and web protection at a very competitive price. Boasting an abundance of features and receiving top marks in testing by independent laboratories like AV-Comparatives, this suite also provides exceptional customer support as well as offering a risk-free 30-day trial for its customers.

McAfee Virus Definitions version 8.5 was released in October 2015 and offers a variety of scanning options from default full scan to heuristic analysis that detects potential threats and vulnerabilities. Memory scans help detect hidden and dangerous threats while its Shredder feature safely erases files to protect privacy on computers or mobile devices.

Early versions of McAfee VirusScan Professional included VirusScan, later rebranded as McAfee VirusScan Professional in 2008. Major upgrades for this version of VirusScan included Leopard compatibility (a universal binary package that runs on both Intel- and PowerPC-based Macs), on-access scanning capabilities, enhanced worm and spyware detection and real-time scan engine integration with low system footprint.

When using McAfee products in a business environment, you can set up a single DAT file repository on a server and distribute it via HTTP/FTP to other endpoints. You may also create a compressed SuperDAT package with installer support – no matter the product. We strongly suggest checking for updated Virus Definitions regularly!

McAfee earned a 100% malware detection rating in tests by AV-Comparatives and is one of the few antivirus scanners with an effective parental control package for Android and iOS devices, memory boosting feature, theft protection feature and online backup service for cloud files.


McAfee Virus Definitions is an antivirus program that keeps your computer protected against various forms of malware, such as viruses, spyware, malicious programs and Trojans. To do so effectively it constantly monitors the Internet for new signatures of virus-like threats that it then incorporates into its database. Furthermore, McAfee includes a feature to warn of potentially hazardous websites; when visiting one considered dangerous by McAfee you will receive an alert notification as well.

This program can also assist you with recovering corrupted files by employing its advanced backup system that automatically saves copies of each file on your PC and sends them off to a remote server whenever the antivirus detects that one has changed. Furthermore, its built-in antivirus scans your files for suspicious activity so it can detect corrupted ones and replace them with original copies more efficiently than before.

McAfee Virus Definitions also offers a powerful anti-malware feature to quickly and safely eliminate malware on your device and detect new threats before they breach it. With one of the largest databases of viruses and malware available, McAfee can also detect phishing sites, spyware and adware programs, keyloggers Trojans and more!

Ransomware is a form of malware that encrypts files and demands payment in exchange for their release. By alerting you of any attempts at encryption and creating backup copies of each encrypted file, this software offers protection from ransomware threats that encrypt them – so if they persist you can restore them from their backup and continue using your computer normally.

Antivirus scanner is another impressive feature of this software, scanning both files and browsers for any suspicious activities that could indicate virus-like activity or hidden code running in the background. QuickClean also cleans out cookies or temporary files which could give hackers information about you or track you online.


McAfee Virus Definitions are files containing the most up-to-date virus signatures for antivirus software to use to identify viruses and malware, and regularly updates them as new threats emerge. Antivirus software serves as a highly trained security guard by constantly watching for signs of danger – checking master databases for threat updates as well as performing routine maintenance checks to make sure its protection provides maximum effectiveness.

McAfee Virus Definitions differ from competing solutions by being compatible with all major versions of Windows, both 64-bit and 32-bit. Furthermore, they run on numerous servers including 32-bit Microsoft Small Business Server 2011, 64-bit Microsoft Windows Server 2008 R2, both 32-bit and 64-bit versions of Exchange Server 2007, as well as its 64-bit counterpart in Exchange 2003 with SP2.

One feature, Ransom Guard, monitors your computer for ransomware attacks. As soon as it detects an attempt at encryption of files, Ransom Guard takes immediate steps to increase security by creating protected copies and, if needed, will restore these from backup copies.

QuickClean is another feature designed to assist in cleaning out temporary and other files consuming space on your PC, increasing performance while helping deter hackers from accessing personal data that could compromise it.

McAfee Global Threat Intelligence provides enabled products with real-time threat evaluation across file, web, message and network vectors in real-time, providing broadest threat data coverage and most robust product integration available today.

McAfee Small Business Toolkit offers both standalone antivirus software as well as comprehensive business security suites that include antispyware, firewall and data encryption programs; mobile security features for iOS and Mac users. Managed through a central console, businesses that use the toolkit can deploy policies, manage alerts and generate reports automatically.


McAfee Virus Definitions is software designed to keep your antivirus program current with the most up-to-date signatures for viruses, malware and other threats by continuously checking the Internet and compiling these into one package. As one of the more renowned names in this space for nearly two decades now, Virus Definitions stands out.

Although large outbreaks of viral infections are no longer as frequent, the amount of malicious software being produced continues to increase exponentially. Security vendors have responded by adding more antivirus definitions than ever to their threat databases – leading to antivirus software becoming overloaded, slowing PC performance more than expected.

Now there is an effective solution for this dilemma – creating a local repository of McAfee virus definitions can be updated manually or automatically via HTTP or FTP, keeping all endpoints up-to-date even those without Internet connections. Simply install Insite PTAV Service onto a server you intend on using as the DAT file repository, connect all endpoints, and start updating as usual!

Once connected to a server, each endpoint can be configured to retrieve virus definitions from the repository using any standard Internet browser. You can specify which port or IP address the repository should use so you can control how your endpoints connect. In order to ensure only valid DAT files exist in the repository, Powertech Antivirus can also be configured to validate them before permitting endpoints access them.

Once you have established a working repository of McAfee Virus Definitions, it is vitally important that it is kept current with regular updates. This will enable your antivirus program to detect and eliminate newly discovered viruses, malware and digital threats as they emerge. When no longer required, McAfee Virus Definitions can be uninstalled as any other app; simply press Windows button + R to access control panel > programs & features > programs & features find it then click uninstall button.
