Msiexec.exe was detected as Trojan.agent as was taskhost.exe. Both were found in C:\windows\system32. 1st time it was detected I quarantined it only to discover msiexec.exe is required to install Microsoft updates, Microsoft tools, and some programs using Microsoft installers. Malwarebyte anti-malware would not restore the essential executables. System restore also did not restore these files either. I believe Malwarebytes Anti-Malware was corrupted. It took me a long time to replace these files. And many others are unrestoreable thus far. FYI don't repair these files by the guideline set by Microsoft. What is an easy way to report this false positive on this site besides the forum section? And how does one get support within a reasonable time? I wrote support and an automatic response returned that they will get back to me in three or four days. They were busy.
