I accessed WhatsApp Web on a computer with a virus
"The following happens: I downloaded WhatsApp on my phone, which had a backup linked to my email. I accessed WhatsApp Web on a computer with a virus, logged out from there, reset my phone to factory settings, reinstalled WhatsApp, but it no longer had the backup. Then, I accessed WhatsApp Web again. Is there a risk that some virus could once again access the information that was in my backup?"
It's also possible that when accessing WhatsApp Web on the computer with the virus using the backup, the virus may have collected information even though I later logged out. I approximately opened WhatsApp Web for 20 minutes
Even though not all my chats and messages had been synchronized yet, that may have prevented the virus from collecting that information that hadn't been synced?
