It is always advisable to scan a file downloaded from internet before running it, because some people share virus and malicious code packed with files that not only corrupt your computer but can also steal your personal data. Moreover it is a known fact that an antivirus program alone can’t detect all threats, so you can make use of online scanning tools which are free and effective. These tools scan for any virus and display the result of the files.
