Windows users have been using on-demand antivirus programs for decades, and every user has a favorite free or paid antivirus installed. Personally, I change my Windows antivirus program about once a year, based on the excellent metrics published at the Shadowserver Foundation.
Mac users are not far behind these days. Even though a Unix-based operating system like OS X El Capitan is inherently far more secure, the justification for installing antivirus software on Macs is Windows-based malware can still be stored and shared on Macs. In my experience, both Avira and Sophos antivirus for Mac OS X El Capitan do commendable jobs.
With mobile devices and smartphones easily outnumbering desktop and laptop computers now, Antivirus for Mobile Devices, especially Android-based smartphones, tablets and phablets, are also provided by many of the antivirus software shops now.
With the threat to computers moving away from viruses towards Trojans, malware, ransomware. adware, and PUP (Potentially Unwanted Programs) and bots like the recent Mirai running on your devices connected to your home network that make up your internet of things (IoT), just having a antivirus program that performs on-access scans is not quite enough. I regularly run a suite of on-demand scanners, all free, that troll through the memory and file systems of my computers, finding and neutralizing any threats missed by simple on-access scanners, as well as adware, malware, unwanted programs and more.
All of these malware scanning tools are on-demand, i.e. you run them periodically by manually launching them. They typically download the latest engine and definitions and perform a deep scan of your hard drives, and also provide options to clean out any malware they identify. They are all designed to be run even if you have a primary antivirus solution installed that performs real-time scans as files are accessed by the operating system.
Special mention must be made of the collection "EU Cleaner" from botfrei of Germany. They provide prepackaged bootable antivirus images that will be invaluable when you are trying to recover from an infection. For example, their Anti-Bot CD is a bootable disc image that you can create a CD from that boots into a Avira scanner environment to scan and neutralize threats on an infected PC.
Note: The text descriptions for each of these tools below contain excerpts of the manufacturer web-sites for these tools. Also, I ran some of the following tools under Sandboxie sandboxes, as indicated by sandbox names in the title-bar or yellow borders around the windows.
The open source ClamWin antivirus (www.clamwin.com) uses the ClamAV engine and is available under a GNU General Public License by the Free Software Foundation. Virus database updates are free too. ClamWin is a on-demand scanner, and does not come with any on-access real-time scanning features.
I use the underlying clam antivirus engine with the clamscan and clamdscan tools on all of my unix-derived systems, including Solari 11 and various flavors of Linux. The maintainers of this great free malware scanner are very enthusiastic - updates and detection rates are both pretty impressive. Depending on your primary real-time on-access antivirus solution and resiliance of your firewall, ClamWin does provide a very viable 2nd line of on-demand scanning defense.
Download ClamWin Free Antivirus from here. Also take a look at the Clam Sentinel project if you want to also use the ClamAV engine for real-time on-access antivirus functionality.
