your problem is that yoh have changed the default scan settings....and selected "scan memory"
this will give some veird scan results.....also it is a memory process, not a file so cant be deleted/moved to quarantine so buttons are gray and none working
mspeng.exe belongs to microsoft defender, so you are detecting MSdefender virus signatures loaded in memory
dont use the "scan memory" settings.....if you dont know the result, dont change default scan settings
this is the second most asked question in the forum.
detection in memory / memory scan. searc the forum for more info
the most asked is files that can not be scanned
