By now you know how important it is to use a good antivirus on your PC. Sometimes, however, it can happen that products like Avast, Avira, Windows Defender etc. they "stick" on files that they describe as threats but which are actually harmless: they are called false positives.
If you too find yourself in such a situation and you are convinced that your antivirus is wrong to indicate a certain file as a potential threat, you can take action and add the "offending" object to the exceptions, ie the files that the antivirus does not have to take into account during its scans.
If you want to know more and are 100% convinced of the safety of the element that is reported to you as a virus, read this guide of mine dedicated to how to exclude a file from antivirus, valid for both Windows and macOS. It's a lot simpler than you might think, you have my word. Then? Are you ready to get started? Yup? Very well. Let's put the chat aside and start getting busy right away!
Before getting to the heart of the matter by discovering, in practice, what are the steps to be taken with the various antivirus software to exclude a file from the analysis process, it seems necessary to make some clarifications in this regard.
Usually, antivirus are quite accurate in being able to identify cyber threats, so, in principle, it is always good to trust the "judgment" given by such software. But I wrote "usually" because, however flawless they may be, even the best antivirus have margins of error and can indicate files that are not actually malicious as malicious.
But how to to recognize a file actually safe from a virus? Assuming that in the case of files from dubious sources (e.g. the executable of a program downloaded from an Internet site you have never heard of) it would be good to trust the antivirus opinion, to do the so-called "litmus test" I suggest you go to the website Virustotal.
In case you have never heard of it, it is a renowned free Web service that allows you to check the security level of any file using the engine of over 70 of the most reliable antivirus on the market. It works directly from the browser window, without downloading absolutely anything to your PC and without making any registrations.
To use it, go to its home page, click on the button Choose file and select the file to be scanned (it must be 128 MB maximum). Next, hit the button Scan and wait for the file to be uploaded online first (if necessary, many files have already been scanned by other users and therefore you can directly view the report) and then processed by the system and you will be given the response. For more information, I refer you to reading my specific guide on online virus scanning.
