![]() ![]() Read More: What Does Antivirus Software Do? Heuristics is about detecting virus-like behavior or attributes rather than looking for a precise virus signature that matches a signature on the virus blacklist. Files run in Comodo containment are kept in a sandbox environment, separate from your operating system. If suspicious code is detected then the antivirus deletes the file or recommends it for containment. Heuristic detection describes the method of analyzing the code of a file to determine if it contains code commonly found in malware. Modify the code slightly, and the malware is rendered undetectable.Ĭomodo Antivirus also uses heuristic detection and containment to ensure that even unknown malware cannot compromise our users’ computers. Like a wanted outlaw in the old west, a cybercriminal can disguise a piece of malware to avoid detection. This process is executed quickly and is an essential feature of an antivirus software, but it is also easy for cybercriminals to evade. Specific detection works by scanning a file for a specific set of characteristics and checking these characteristics against a known list of malware. This is what most people think of when they think about how an antivirus works. The most basic detection process is known as specific detection. Most modern antivirus programs feature multiple scanning detection processes. Data Safe 4 is only available in the paid-for edition of the program.Whenever you download or launch a file, an antivirus program scans the file for malware. 2 The menu button 3 provides access to Settings, Quarantine and the File Shredder. However, you need to install AVG PC TuneUp to fix these problems for free. You can also schedule scans from the same screen.ģ Once you’ve run a full scan, the results screen will display any threats it’s found, 1 along with any junk files. 1 Clicking the cog 2 lets you choose the type of scan you want AVG to run: Full Computer, Deep Virus, USB/DVD, File or Folder, Performance or Boot-time. 2 Basic Protection shows you which modules are active.Ģ To check your PC for threats, click the Scan Computer button.

MINI WORKSHOP – Protect your PC using AVG Antivirus Free 17ġ During installation, you can choose the Custom option to specify the components you want to include. ![]() Happily, it appears that AVG fans, who may have thought the program would change radically – or even be scrapped altogether – under Avast’s ownership, needn’t have worried. If, during setup, it identifies an antivirus program already on your system, it will install itself in ‘Passive Mode’ to avoid any potential conflicts. You can now use AVG as a second line of defense, as well as your sole security program, because it will install and run without problems alongside any existing antivirus software you might have installed. The software can also identify performance problems. This 17th version of AVG Antivirus uses Avast’s cloud-based file scanner, CyberCapture, to protect your PC against zero-day threats, and has an improved Online Shield that blocks malicious links and files when you’re browsing the web. These ensure that free users get the same speedy updates and protection enjoyed by owners of paid-for AVG products. There are plenty of welcome changes throughout the software, though, such as the introduction of Pushed Priority Updates. The latter safeguards you from hacker attacks, hides your private files and offers payment protection when you’re shopping online, but you’ll need to upgrade to the paid-for edition to unlock this functionality. The main screen is divided into two sections – Basic Protection and Full Protection.
