Not happy. Actually is "Reg Clean Pro".
katy_loweSeptember 26, 2013
Pros
It started running by itself after easy installation and found over 3,000 registry errors. Hopefully. Read my cons. If all my reservations about this program are answered, then maybe I will come back and give it 5 stars.
Cons
I did the install, despite the fact that it did NOT have the "Microsoft Windows Malicious Software Removal Tool 64-Bit" name that CNET said it had. It is actually "Reg Clean Pro". It scanned and found over 3,000 registry errors but said it could only fix 15 for free. Unless I bought the full version. What?? First, I don't like that CNET did not have it described with the correct name or at least explain what would happen once you started the download process. Second, I don't like that I was given the idea that it was free (Hey, it said Free in the left side frame!) and it turned out I had to pay for the software to be fully operational.
Summary
Maybe it is good. Maybe they really did find 3,000 errors with the 'free' one-time scan. But doesn't it feel like some sort of scheme for so many errors to be found but not all would be fixed UNLESS I PAID UP and bought the thing? This reminds me of the "protection money" stuff by the mobs in big cities back in the 1920's. I doubt this is the case, but gee, how do I know? I bet many older, non-techy people like me want to use and trust professional reviews and downloads simply because we don't understand all this. So, please make it straight forward with no surprises!!
It worked for me.Had viruses and spyware on my p.c.

Pros
My computer was running very slow.a friend recommended I try this.It found 3 viruses and several spyware.It removed them.And then run cc cleaner to repair the registry.My computer is working good again.
Cons
This is a good tool.But it targets specific offenders.It may not work for You.But it is worth a try.
Summary
I have had problems with spyware and viruses.I feel that this any spybot s&d are good tools to get your pc running again.Be cautious of the add on bars for your browser.

Developer’s Description

Protect your system from different virus attacks.

Microsoft Windows Malicious Software Removal Tool (64-Bit) checks Windows Vista, WIndows 7, Windows XP, Windows 2000, and Windows Server 2003 computers for and helps remove infections by specific, prevalent malicious software--including Blaster, Sasser, and Mydoom. When the detection and removal process is complete, the tool displays a report describing the outcome, including which, if any, malicious software was detected and removed. The tool creates a log file named mrt.log in the %WINDIR%\debug folder.
