Associated filename - TrustedInstaller.exe
After continuing issues with slow performance and repeated attempts to install malware and direct my browser to malware sites, I traced the offending process and found that this is the prime installation package. It hijacked file/folder permissions in several critical areas. I found and eliminated about a dozen registry entries and then reset permissions on files and folders and submitted files to Avast, since their AV did not register this as malware, only the recognizable malware it tries to install. Microsoft's malware software failed to detect it miserably, as well. Hopefully this puts an end to this little nightmare.
