WAIT!

Before you format her computer, everyone should know that the "Vista Secuity Tool" is a fake anti-Malware app. I've never heard of that one before but what tipped me off was looking at your screenshots. It gives a few signs that it's not a real one:

• It says to "activate" it so you can start cleaning your system. Most likely for a price.
• There are a lot of exclamation points in the alerts. Generally, programmers don't use many exclamation points in legitimate, professional software.
• The sense of dire emergency it portrays. Real anti-virus / anti-spyware apps will generally just show that you have an infection. It doesn't make it sound like a life or death situation.
• Real scanners won't flood you with alerts. You generally just get one big window listing all of the infections.
• Improper grammar / spelling. For example: "Windows recommend Activate". It should be "Windows recommends activating ...".
• Use of certain "Buzz words" to make people freak out. Like the word "Hacked". Real scanners won't say "System hacked!", or "Identity theft detected!". "Identity theft" being another big, scary buzz word.

So I googled "Vista Security Tool" and sure enough, I was right. Take a look. You can google that phrase for more on it too. What I would do, is use those instructions to remove the "Security Tool", and then run a few REAL scanners on the system. It looks like SuperAntiSpyware run in Safe Mode will also remove it. Chances are it's probably clean other than that, but there may be something on there still seeing as that one somehow got on there to begin with.
