At the same time when Google URLs were blocked earlier I ran a virus scan and it totally nuked like 40+ PDFs. from my OneDrive. I had to go an restore them all via ESET and re-ran with ESET and other scanners which showed up safe.
PDF/Phishing.A.Gen trojan - cleaned by deleting [1]
Did anyone else have this issue you too? It freaked me out a bit, and if i didn't notice I would have just lost tons of important PDF documents etc.
You might want to check your ESET logs to make sure the native scanner didn't go nuts.
