Frustrated. Ugh!

Since Friday my Outlook email has not been working. Friday morning I signed in and it stated that my Windows Defender and Windows Firewall was blocking a trojan virus well ever since then I have not been able to get my email working for work. Ugh. I'm so frustrated. I tried to restore the computer back to a later date when I was not having any issues but nope still can't get signed on. Now I'm having to use the back door get in to get my mail but it's a pain in the butt. I just want to be able to use my email the way everyone else does. The only other option I might even remotely have is to make sure all my items in my mailbox are backed up and then go in and reinstall the silly thing. If anyone knows if there is another way to get the stupid thing working again please let me know!
