This video introduces VirusTotal, a website owned by Google that allows users to scan files and URLs with 70+ antivirus engines simultaneously. The video demonstrates its use, explains its features (including file uploads, URL scans, and hash lookups), and highlights additional tools like the VirusTotal Uploader and VT4Browsers Chrome extension.
The video suggests that a single "suspicious" result from one antivirus engine, without corroborating evidence from others, might indicate a false positive. Conversely, numerous antivirus engines flagging a file as suspicious strongly suggests a genuine threat. The community score and comments can also help determine if a result is a false positive, although this is not foolproof because it could be manipulated.
The video doesn't specifically address the scenario of only two antivirus engines flagging a file. However, the overall guidance is to consider the number of positive results in context with other information. Two positive results would be less conclusive than many positive results, but still a reason for caution. Further investigation, such as examining the specific warnings from those two engines and checking the community score and comments, would be prudent.
