I am a 25 year computer technician we have a small store in Canada, we work with weird problems and issue like this everyday. When you have been doing this as long as I have you figure you have seen it all when it comes to viruses and malware, but everyday
there is something new. Remember
I am not sure if anyone is still having this problem but I have been fixing the myriad of problems that Windows has thanks to viruses/malware/hackers.
Here is the easiest solution I can give you and hopefully it will be of some help:
Download and run this file

You can find more TOOLS at http://support2.microsoft.com/fixit/
If fixes issues with Windows Installer and many other issues. I would also suggest that you scan your computer with more aggressive virus/malware programs.
Here are some suggestions:
www.malwarebytes.org (malwarebytes and more aggressive tools under the TOOLS menu)
ESET online scanner (eset online virus scanner, when you run it CLICK advanced settings
and check all check marks but the last one, it will then download Virus definitions, once it starts scanning DISCONNECT your computer from the internet)

*****ABOVE ALL IF ANYONE CALLS YOU FROM YOUR CABLE COMPANY, MICROSOFT, HP, DELL, or anywhere else UNSOLICITED, tell them you "do not own a computer and have a nice DAY" or say "What's a Computer" they will usually hang up and erase your number.*****
One of my favorite Blogs to read about the insane lengths cybercriminal go to, to infect your computer is:
Krebs on Security
Also remember Microsoft spends multi millions of dollars chasing down cybercriminals, they do not just sit back and watch it happen.
Hope it helps
