VirusTotal is an online service, that is available to you (for FREE), that analyzes suspicious files and URL’s. Typically, to use the service you visit VirusTotal [ HERE ] and upload the file in question or enter the questionable URL (web address). VirusTotal will go to work scanning the file against numerous antivirus engines OR will go to work reviewing any URL you submit using multiple analysis tools.
I know you are thinking, why would I need to do this, especially when I already have security software installed on my PC that will automatically check my files for me? It is like this, when we go to the Doctor for something that is suspicious, it is best to get a second opinion. In the case of a suspcious file, VirusTotal is that second opinion.
I have been a user of VirusTotal for a long time; however, I often wondered; “Is there way to upload a suspicious file to VirusTotal and get a result without having to go through the steps of opening my browser and actually going to the VirusTotal site to upload the file?”.
You have probably heard myself and some of the other Techs comment; “If you can think it, someone has done it!”. The answer to that question is “yes”. It is called VirusTotal Uploader.
After you install VirusTotal Uploader, you simply right-click any file under 20MB, in Windows Explorer, and choose “VirusTotal” from the Send To Windows menu. The scan results will display in your browser as usual. Wow, what a neat concept…
As someone that loves testing free and open source software, I will often pipe the install file to VirusTotal to make sure all is right. One thing to keep in mind is that there are occasions where “false positives” will occur with a service such as this; however, VirusTotal will help keep you security conscious and on your toes.
