Is the Eicar test file safe?
The Eicar test file is not as harmful as most of the other malware files out there. And it’s not even a virus at all. It was initially developed by the European Institute for Computer Antivirus Research to help test the effectiveness of antivirus software. But for whatever reason, it has recently been used to find vulnerabilities on a computer, so they could later be exploited by more harmful malware.
The thing that makes the Eicar test file worrisome is that it can be a sign you have other malware installed on your computer. Or it could act as a false positive, tricking your antivirus into thinking that it’s a problematic file and ignoring files that could actually cause issues.
So, if you think you have the file saved somewhere on your hard drive, then it’s a good idea to go ahead and scan your entire computer for malware and suspicious software.
Keep reading to learn the quickest way to remove the file and how you can check to see if any other suspicious software has used the file to sneak onto your machine.
How did the Eicar test file end up on my computer?
There are a couple of ways you could have ended up with the Eicar test file saved to your Mac’s hard drive. The first being rogue pop-up ads. You might have accidentally clicked a pop-up ad on one of the websites — this could start the download of malicious files. One of those files could potentially have been the Eicar test file.
The second way, which is much more likely, is that the Eicar test file was bundled with some other software you installed. Malware and other potentially unwanted programs will hide in installation bundles. The best way to make sure you’re only getting the app you want is to make sure you always click “Customize” or “Custom Install” during the installation process.
By always doing a Custom Install, that gives you the chance to see if anything else is being installed. For legitimate apps, this window will typically just show you extensions and added features. But, it’s also where the app will tell you if it has any sneaky software it’s trying to get past you.
