VirusTotal is an awesome online malware/virus scanner that allows users to scan files and programs for viruses or malware using over 40 different anti-virus/anti-malware engines.
Maximum file size limit for VirusTotal was 20 MB. Once we will not be able to scan files more than 20MB. Last year Google bought VirusTotal and change the maximum file size limit to 32 MB. It was a big change. Recently VirusTotal has increased their maximum file size limit to 64 MB.
It was happen sudden there was no official announcement regarding the increase in file size. We can see and understand how Google’s massive cloud infrastructure would help improve VirusTotal.
