In the past we saw popups with command prompt Taskeng.exe. The popups quickly disappeared before we could do a screen capture. MalwareBytes and Windows Defender were not able to catch anything. We re-configured the laptop by reverting the Windows 7 operating system back to the mfg state, and then re-added software apps that we own, We also loaded data from a back up copy. We then upgraded the os to Windows 10. It was fine for a while until a few days ago, we saw malicious website protection messages from Malwarebyte, and outbound traffic to a known malicious domain was blocked. The taskeng popups came back just now. Once again scan with MalwareBytes returned nothing. What should I do now to eliminate the problem?
Here is the relevant log entries on the blocked traffic:
