Security software is good at protecting PCs from malware such as viruses, but individual programs can sometimes
get things wrong and allow harmful programs to slip through. One solution is to use VirusTotal, which provides 57
tools to scan any suspicious file you send it. We’ve been able to use it on the web for a while, but now its updated Uploader makes it even easier to use from your Desktop.
OS System: XP, Vista, 7, 8, 10, OS X
Step 1: Download VirusTotal Uploader and double-click it to install the program. This adds an extra item to the menu that appears when you right-click a file in an Explorer window. To use it, right-click a file, such as one in the Downloads folder, and select ‘Send to VirusTotal’ from the menu.
Step 2: Small files upload quickly, but files of several megabytes could take a few minutes. The maximum size allowed is 32MB. If you have a problem uploading a file, click ‘Close this window’ (sometimes it says Cancel), then click the
‘Reupload files’ button below
Step 3: Your default browser opens to display the results. The ‘Detection ratio’ is the number of security programs
that report the file as malware – in this case, 11 of the 57 programs. The image on the right of the screen shows whether any people have reported the file as safe or malware.
Step 4: Scroll down to see more results. In this case, popular programs like Avira, ESET and Sophos report our file as
malware, but AVG, Ad-Aware and BitDefender don’t. Often the results indicate clearly that a file is malware or safe,
but not always. Treat files with mixed results as malware.
Step 5: Double-click the VirusTotal Upload icon on the desktop to see a list of programs running in the background. Select an unknown or suspicious file, then click ‘Upload process executable’. You can also select files on the hard drive and upload those.
Step 6: This file received a clean report from all 57 security programs. Select the ‘File detail’ tab to find out more about it. The Copyright entry shows that it is from a reputable company. The ‘Signature verification’ and signers
confirm that this is a safe file from a trusted source.
