Yesterday, I was searching in my Gmail for old files that I wanted to download. Once the email opened, I had a particular surprise: Anti-virus warning – 2 attachments contain a virus or blocked file. Downloading these attachments is disabled.
Why do we have this anti-virus warning?
Like I said, this error was kind of surprising since I know for sure those files don’t contain viruses. After reading the Learn more link, I realized that those files were marked as a virus because they contained another .zip file in it. According to this link again, it is also possible to have a file blocked if it figures in the list of the Gmail blocked file type (for example a .bat file). You can take a look to the banned files type list here.
I get Google trying to be secure but this can be a pain at times.
