Bitdefender Online Threat Prevention alerts
Hi to all, I hope you guys have a great day. As you can see in the picture, this problem doesn't need an explanation. What is causing this issue?

Work around for scan unless I am doing it wrong
Once a week I do a complete scan which lasts about 10 hours. The problem is that about 1.5 hrs into the scan it stops (as far as I can tell) and indicates that I have password protected zip files with options of a password, skip or skip all. This is bad because it delays the process esp if I run it over night. It would be…
