Computer Virus Check & Removal
Antivirus products distinguish themselves by going beyond the basics of on-demand scanning and real-time protection. Some rate URLs that you visit or that show up in search results, using a red-yellow-green color coding system. Some actively block processes on your system from connecting with known malware-hosting URLs or with fraudulent (phishing) pages.
Software has flaws, and sometimes those flaws affect your security. Prudent users keep Windows and all programs patched, fixing those flaws as soon as possible. The vulnerability scan offered by some antivirus products can verify that all necessary patches are present, and even apply any that are missing.
You expect an antivirus to identify and eliminate bad programs, and to leave good programs alone. What about unknowns, programs it can’t identify as good or bad? Behavior-based detection can, in theory, protect you against malware that’s so new researchers have never encountered it. However, this isn’t always an unmixed blessing. It’s not uncommon for behavioral detection systems to flag many innocuous behaviors performed by legitimate programs.
Whitelisting is another approach to the problem of unknown programs. A whitelist-based security system only allows known good programs to run. Unknowns are banned. This mode doesn’t suit all situations, but it can be useful. Sandboxing lets unknown programs run, but it isolates them from full access to your system, so they can’t do permanent harm. These various added layers serve to enhance your protection against malware.
Firewall protection and spam filtering aren’t common antivirus features, but some of our top products include them as bonus features. In fact, some of these antivirus products are more feature-packed than certain products sold as security suites.
Among the other bonus features you’ll find are secure browsers for financial transactions, secure deletion of sensitive files, wiping traces of computer and browsing history, credit monitoring, virtual keyboard to foil keyloggers, cross-platform protection, and more. You’ll even find products that enhance their automatic malware protection with the expertise of human security technicians. And of course I’ve already mentioned sandboxing, vulnerability scanning, and application whitelisting.
Which antivirus should you choose? You have a wealth of options. Kaspersky Anti-Virus (2016) and Bitdefender Antivirus Plus 2016 invariably rate at the top in independent lab tests. A single subscription for McAfee AntiVirus Plus (2016) lets you install protection on all of your Windows, Android, Mac OS, and iOS devices. And its unusual behavior-based detection technology means Webroot SecureAnywhere Antivirus (2016) is the tiniest antivirus around. We’ve named these four Editors’ Choice for commercial antivirus, but they’re not the only products worth consideration. Read the reviews of our top-rated products, and then make your own decision.
