Outlook keeps on crashing

I keep on getting a message "Microsoft Outlook must be closed because an error occurred, Any unsaved work may be lost." In my far right hand screen I get a message telling me that infected files have been found at path that goes into the temporaryitems/Outlook Temp/ folder. I think the problem is that I get too much spam and viruses/malaware our whatever shows up in my Spam folder. Outlook seems to be the only app affected by my spam as Thunderbird and Mail just ignore the spam. Does anyone have any ideas?

As a temporary fix I opened Thunderbird and cleared my junk mail folder and opened Outlook and so far it has not crashed. Perhaps it will later I do not know. Thanks..
