5 Best Free Online Virus Scan Services with Multiple Antivirus Engines

It should be common knowledge now that no Antivirus software has a failsafe 100% virus or malware detection rate. Occasionally, a real effective Antivirus can skip a file that’s really a virus and some of the times it can detect a file as a virus when its not really a virus. When a virus scanner fails to notice a virus in a file its called a false negative and  the detection of a file as a virus when its not really a virus is called a false positive.

In order to save your files from false positive and false negative you can use online virus scanners with multiple antivirus engines so you can more easily decide if a file contains a virus or not.
