After many hours of un-installing/installing, research, this is what happened:
1) I uninstalled Trend
2) uninstalled Mal-Ware Bytes...I didn't know I had this, as there was no desktop, or task bar icon.
3) Noticed that 'TrustedInstaller' was 'stopped' in task manager/services, at first, I got 'unable to start service', but after a few trys, it started.
4) Re-installed Trend, and a 'C' scan to completion(first time in 5 weeks)
5) Re-installed Mal-Ware Bytes, ran a 'C' scan OK
6) Ran another Trend 'C' scan...it hung.
So, it seems that Trend work fine by itself, but hangs when Mal-Ware Bytes is running.
7) Un-installed both Trend and Mal-Ware Bytes
Installed Mal-Ware Bytes first this time, then...
9) Installed Trend.
10) Ran a Trend 'C' scan, it hung.
Not sure why this is happening now, as I've had Trend and Mal-Ware Bytes(unknown to me) running for years. Maybe one of the Trend updates has made it impossible to work with Mal-Ware Bytes?
So, after all this, I have just Mal-Ware Bytes running. I have about 6 months left on my Trend subscription, but it's only about $18...so no big deal.
My two questions now are:should I have 'TrustedInstaller' stopped, or running in Task Manager\services? And, is just having Mal-Ware Bytes(Premium 3.1.2) going to be sufficient protection?
(Latest:'TrustInstaller in Task Manager\Services is Stopped, and I get 'Access Denied' when trying to start it...is this a concern?)
For every scan Mal-Ware Bytes checks for updates, pre-scan operations, scan for rootkits, scan memory, scan startup files, scan registry, scan file system, and Heuristics Analysis.
In the Mal-Ware Bytes dashboard, it has:Web Protection On, Exploit protection On, Malware protection On, and Ransomware protection On.
If just running Mal-Ware Bytes is not going to be enough protect, can the forum community recommend a anti-virus-mal-ware-ransomware/internet protection product? OK if paid.
According the Mal-Ware Bytes web site, it does this:
Protects you from advanced (zero-day) threats, including ransomware, so you can surf the Web without worry
Removes all traces of malware for complete safety
Removes potentially unwanted programs (PUPs) that make your computer run poorly
Scans fast so you don't have to sit around and wait for your security to finish working
Easy to use, just set it and forget it
Can replace antivirus or run alongside other antivirus programs(eh, this part not true)
