How Does Antivirus Software Work?
Every time you download or launch a file, an antivirus program scans the file for malware. Most modern antivirus programs have more than one scan detection process. The most basic detection process is known as specific detection. This is what most people think of when they think of how an antivirus works. Specific detection works by scanning a file for a specific set of characteristics and comparing those characteristics to a known list of malware. This process is performed quickly and is an essential feature of antivirus software, but it is also easy for cyber criminals to evade. Like an outlaw wanted in the Wild West, a cybercriminal can disguise malware to avoid detection. Modify the code slightly and the malware is made undetectable.
RAM Antivirus also uses heuristic detection and containment to ensure that even unknown malware cannot compromise our users’ computers. Heuristic detection describes the method of analyzing a file’s code to determine whether it contains code commonly found in malware. If suspicious code is detected, the antivirus either deletes the file or recommends it for containment. Files executed in RAM are kept in a sandbox environment, separate from your operating system. Heuristics are about detecting virus-like behavior or attributes rather than looking for a specific virus signature that matches a signature on the virus blacklist.
Best Antivirus for Windows Devices
The best antivirus for Windows devices should have features that protect your Windows PC from the holes left by Windows Defender. Features like anti-spam, adware prevention, and safe browsing are essential for Windows users.
Do You Need Antivirus for Windows 10?
Windows Defender is a good tool that offers more than basic protection, but it has been shown by AV Comparatives and other tests to lag behind other antivirus programs when it comes to protecting your PC, and lacks some essential security features, including password managers. To ensure complete protection, relying on Windows Defender is not enough. An additional program, like RAM Antivirus for Windows 10, is needed to fill in the gaps left by Windows Defender.
Pick software with a high malware-detection rate
You need to make sure that the antivirus software blocks more than 95% of malware, whether it’s common malware or brand new zero-day malware. But make sure that the detection rate is not accompanied by a high rate of false positives, which are benign files mistakenly flagged as malware.
Pay no more than you need
Most antivirus manufacturers sell at least three types of Windows products, each more expensive than the last. But every single-brand product will detect Windows malware as well as its stable companions.
Look for a light system load
You’ll want to read Tom’s Guide to Antivirus Software Reviews to see how each product slows down a machine, both in the background after it’s installed and during active malware scans. This is especially important for older, slower PCs that need antivirus software the most.
See how easy the software is to use
Most antivirus users want a configure and forget option, but sometimes it’s good to go under the hood and tweak the software to your liking.
Don’t settle for the brand that came with your PC
Many new Windows PCs come with one or three month trials of well-known antivirus products. But you will have to start paying them after the trial period is over. Don’t give in – instead, shop. You might be able to get something better for the same price or even less.
