If you come across a file that appears suspicious, it’s best not to take any chances and have it analyzed by an antivirus program. There are numerous websites that offer file scanning services for viruses, which can be a good alternative to using a local antivirus solution. However, this method has both advantages and disadvantages when compared to local solutions.

One advantage of using an online virus scanner is that it typically uses the latest virus definitions, which is a good sign. Additionally, you may be able to run the scan directly from your web browser, depending on how the scanner is made available, and you can be reasonably sure that it hasn’t been compromised by malware. However, this is only the case if the company behind the service regularly updates it with the latest virus definitions and takes steps to ensure that the service has not been compromised.
On the other hand, the main disadvantage of online virus scanners is that they often have file size limits, meaning you cannot scan large files. Most sites have a limit on the size of the file that can be scanned, which can be a problem if you need to scan a large file.
