Ad-Aware Free Antivirus+

Ad-Aware Free Antivirus+

Ad-Aware Free Antivirus + from Lavasoft provides core protection against internet threats. Featuring real-time antivirus and anti-spyware engines, rootkit protection, download protection and web filters for safe browsing, the product gives you the power to protect yourself online. Ad-Aware Free Antivirus + provides complete anti-malware protection, combining Lavasoft’s pioneer technology for anti-spyware with traditional antivirus protection.

Ad-Aware was originally developed in 1999 to highlight web beacons inside of Internet Explorer. On many websites, users would see a tiny pixelated square next to each web beacon, warning the user that the computer’s IP address and other non-essential information was being tracked by this website. Over time, Ad-Aware added the ability to block those beacons, or ads. Ad-Aware no longer makes the user aware of the ads on the screen; instead the program fights spyware, adware, viruses and other malware.

In the 2008 Edition, Lavasoft bundled Ad-Aware Pro and Plus for the first time with an antivirusscanner, which used the Avira engine and this arrangement continued for a few years.  Starting with Ad-Aware version 10, the Bitdefender antivirus engine was used instead.


Malwarebytes Anti-Malware 

Malwarebytes Anti-Malware

Malwarebytes’ Anti-Malware (MBAM) is an antivirus for computers running under the Microsoft Windows operating system that finds and removes malware. Made by Malwarebytes Corporation, it was first released in January 2008. It is available in a free version, which scans for and removes malware when started manually, and a paid version, which additionally provides scheduled scans, real-time protection and a flash memory scanner.

MBAM is primarily a scanner that scans and removes malicious software, including rogue security software, adware, and spyware. MBAM scans in batch mode, rather than scanning all files opened, reducing interference if another on-demand anti-malware software is also running on the computer.

MBAM is available in both a free and a paid version. The free version can be manually run by the user when desired, whereas the paid version can perform scheduled scans, automatically scan files when opened, block IP addresses of malicious web sites, and scan only those services, programs and device drivers that are currently in use. MBAM’s user interface is available in 29 languages.


Microsoft Windows Defender

Microsoft Windows Defender

Windows Defender, formerly known as Microsoft AntiSpyware, is a software product that helps combat malware. Windows Defender was initially an antispyware program; it is included with Windows Vista and Windows 7 and is available as a free download for Windows XP and Windows Server 2003. In Windows 8, however, it is upgraded to an antivirus program.

Before Windows 8, Windows Defender featured antispyware capabilities. It included a number of real-time security agents that monitored several common areas of Windows for changes which may be caused by spyware.

It also include the ability to easily remove installed ActiveX software. Also integrated support for Microsoft SpyNet that allows users to report to Microsoft what they consider to be spyware, and what applications and device drivers they allow to be installed on their system. In Windows 8, functionality has increased to offer antivirus protection as well. Windows Defender in Windows 8 resembles Microsoft Security Essentials and uses the same virus definitions.


AVG AntiVirus

AVG AntiVirus


AVG continues to be one of the most popular free antivirus programs available on the internet and it maintains this position with a combination of effective protection and an easy to use interface.

AVG Anti-Virus Free Edition improves on both areas, and is an essential upgrade, as updates will be stopped for the previous version. If you already have AVG installed it is best to click on the upgrade option when it is offered. If you have never installed it before, this is the download to use. We would recommend disconnecting from the internet during installation as there will a period where there is no protection.

As noted the interface of AVG Free has been improved and it is easier to see what protection AVG is providing and what needs attention via icons in the main part of the screen. Tabs along the left hand side give quick access to important information on updates and ongoing scans.

In addition to traditional antivirus protection, AVG Free now offers protection from Spyware without installing extra software.


Bitdefender Antivirus

Bitdefender Antivirus


The best antivirus programs don’t simply detect malware. For what’s often an additional cost, they come with other features designed to protect users’ online privacy and security. Enter Bitdefender Antivirus, an entry-level antivirus program that includes extras often found in pricier packages: profiles for performance optimization, a secure browser that makes online shopping safer and even a “rescue disk” mode to clean up hard-to-reach malware.

The impressive range of features, combined with a slick, user-friendly interface and top-notch malware protection, makes Bitdefender Antivirus Plus 2015 our top pick for entry-level antivirus software in 2015. Bitdefender Antivirus Plus 2015 is compatible with Windows Vista, 7, 8, 8.1 and even Friday XP, despite Microsoft’s termination of support for the latter. The company also makes the Mac and Android antivirus software.

Beneath the protection status are four square icons: Protection, Privacy, Tools and a fourth quartered into smaller icons: Scan, Update, Safepay and Optimize.Bitdefender Antivirus Plus 2015 has a small circular widget that displays independently in the lower corner of the computer screen. Except for stylistic “flattening,” the widget’s design is mostly unchanged from previous years; it displays the computer’s current status in green, yellow or red. Clicking on the widget launches the main interface.

Overall, Bitdefender Antivirus Plus 2015’s interface takes itself quite seriously, but the white and colored text on the gunmetal-gray interface keep it from being overbearing. Except for the activation switches, the tools are well-organized and well-explained.


avast! Free Antivirus

avast! Free Antivirus

The installer is completely configurable when it comes to shields (for files, emails and web), security tools and preferred languages. Since it is ad-supported, the utility offers to install unnecessary third-party components but they can be skipped.The security tools include browser protection and cleanup (e.g. Internet Explorer, Google Chrome, Mozilla Firefox), software updater for other programs installed, remote assistance for access on other computers, SecureLine for connection encryption against spyware via VPN, GrimeFighter for system cleanup and maintenance, Rescue Disk for worst case scenarios with malware-crippled PCs, and a simple management connector that reports the Avast status to COM monitoring software.

Avast is wrapped in a pleasant and easy-to-use interface which provides fast access to the av status, scanning methods, tools, portable devices with Avast installed for remote control (smartphones, tablets), statistics (real-time and historical data, component status), as well as the rich configuration area.It is possible to perform a quick scan in areas where malware is known to hide, complete by taking into account the entire computer, in removable drives only, custom directories, or at every Windows boot in autostart processes and services.

It is not necessary to change any settings, since Avast has a pretty decent default configuration. But advanced users have the possibility to fiddle with options regarding rootkits, file types, the exact scan areas, heuristics, PUP and suspicious files, archive formats, action on malware detection, scan priority, reports, exclusions, and scan scheduling.Unconfirmed suspected infections sent to the quarantine may be investigated to decide whether to keep or eliminate them, while reports with scan activities may be examined in logs.

The software updater automatically finds updates available for other programs, SecureLine must be purchased before it can be used, the browser cleanup component removes toolbars and resets browser settings to default if necessary, AccessAnywhere requires an Avast account (free) to control the PC from remote locations, and Rescue Disk creates a bootable USB or CD drive with the latest virus definitions to use for offline scanning and cleaning.
