Add me to the list.
I scan weekly (Monday mornings) with MB Free, so this has come up in the last 7 days.
After over a year of zero detections I suddenly encountered these 2 issues this morning.
1: MB refused to run claiming that (as I recall) DNARootKit.dll refused to load and that I needed to reboot and try again, and that this might be indicative of a rootkit. Scary stuff. This happened immediately after my weekly reboot on Windows 7. Okay, rebooted again and this time MB ran but (continued to item #2).
2: After over a year of weekly clean scans, 41 items were flagged and quarantined. 30 registry entries that appear to be ...\TASKCACHE\... entries were quarantined. All of them flagged as MachineLearning/Anomalous.100%. Also 11 files, same reason. 10 of them \WINDOWS\SYSTEM32\TASKS\... with no indication why MB is suddenly unhappy with these. And the final file is an .EXE file used as a launcher for a VB6 program that DEFINITELY IS NOT a problem file. The problem here is that this file is used by a number of people in our company and MB quarantining it is a big problem. This file has been in use for years.
So I question if it has quarantined necessary and/or important task files and registry entries -- I don't know how to tell from the information presented.
I do know that it quarantined a necessary benign file.
Report attached.
.EXE file attached as a .ZIP file.
