![]() A simple notepad document will do just fine. What you need to do is to create an antivirus test file (a. So how do you test your antivirus to see if it’s still active?īasically, you have to create a “false virus” that triggers your AV’s defense procedures. Well, there’s a test you can do to see if it still works. Sometimes you’ll go through a long period where you don’t encounter any online threats and seem to forget that you even have an antivirus installed. Other features to look for: DNS Protection, Password Managers, System Optimization, Phishing protection, Antispam, Browser protection. But file shredders destroy them completely and leave no trace of them on your hard drive.įirewall: Some AVs can filter and scan your internet traffic to detect incoming threats before they reach your device. Under normal circumstances, these invisible files disappear only after being pushed out of their memory block by a new one. But these files can be recovered with a specialized program. It will just make it invisible for you to see. Ransomware protection: Some antiviruses come with ransomware protection and the ransomware attacks won’t be able to encrypt your files.įile shredder: This may come as a shock, but the standard “Delete” + “Clear Recycle Bin” won’t actually delete a file from your hard drive. That’s why many of the free AVs out there can only detect and block malware, but won’t be able to remove it if your PC is infected.įor that, you will most likely have to purchase the full antivirus solution or download a separate piece of software specializing in malware removal. Usually, the cybersecurity industry sees the two functions as being separate. Sometimes, removing malware can be just as important as blocking it in the first place. Basically, the quicker and more frequent the updates, the better. Automatic updatesĪny antivirus software worth its salt will automatically update itself, both to clean up any vulnerabilities it might have and to keep its virus database and capabilities up to date. The industry calls this a “ false positive” and it is a criterion used to judge the quality of an antivirus. This is one reason why some AVs falsely classify some safe programs such as Chrome as a virus. This means that it will consider a file to be malware if it behaves like one, even if it can’t be found in its database. Updated software goes a long way to protect you on the Internet since it greatly diminishes the possibility of malicious hackers exploiting an unpatched vulnerability of your software.īut antivirus programs also make use of something called “ heuristic analysis”. This is one of the reasons why we always advocate for people to keep their software updated, particularly their antivirus. This database is updated very frequently, quite often on a daily basis. That’s why every antivirus software comes with a database of known malware and compares each scanned file to the contents of the database. However, scans cannot be effective if the program doesn’t know what it’s looking for. ![]() Ideally, the scanner should be lightweight and not hog down your device while still having a very high detection and block rate. Plugins based on these technologies can be used to make your PC part of a botnet, inject code or do drive-by downloads. Some AVs also block malicious ActiveX or Java scripts from infecting your PC. Then there is the full system scan, where the antivirus goes through every nook and cranny of your device in order to find malware or any other suspicious software or files. It’s all done in the background, and the scanned file or program only opens once the antivirus has finished the scan. Basically, it scans any new program or file before it’s opened and checks if it is a known malware or if it behaves like one. Reactive scanning is the bread and butter of an antivirus. How does antivirus software work? Things you should know about AV before getting one Virus scanner and script blocking It minimizes the times you have to enter damage control mode to clean up the mess caused by a successful malware attack.īefore you proceed in your journey to find your dream security software, let’s see how exactly an antivirus works. The definition of antivirus software programs goes something like this: A piece of software designed blocks out viruses and other malware from entering your device and compromising your personal data or the hardware itself.Ī good antivirus is a must-have.
