Well, it looks like your computer is infeccted by some sort of virus, as well as a Trojan which probably carried the software to send fake messages about a spyware infection, probably courtesy of AntiSpyware Master. Trojans also can have the power to change original desktop or administrative settings, like being able to open Task Manager or in your case, not being able to change your desktop setting.
There are lots of free anti-spyware software out there but they probably contain adware to pay for the fact that it is free. There are lots of blogs aout, there, here are just a few with the solution you need:

Free Christmas screensavers can be downloaded from Microsoft and Apple websites to be sure of getting malware free downloads. Alternatively they can be found on websites such as iTunes, but you should always check out the validity of the site before downloading as there are many sites that will also download viruses and trojans.
40% of computer users have been infected by a virus.
Try getting KernelEx, but whar are the specs in your computer? laptop or desktop?

I have a mac desktop, and when I downloaded the game it ruined my computer. My computer would shut off or turn on randomly, and when my or my family turned on the computer and it was on the user screen, it was completely white.

Anti virus software is useful, because it protects your computer from getting infected by a computer virus. Moreover, most software will reduce the damage a virus can do to your computer. Mind you, the protection is not 100 %. New viruses come out every minute, so your computer may still be infected before the anti virus software recognizes the virus and is able to remove it.
When looking to put together a new home office for a small business, a great computer option would be to get a laptop notebook computer. Getting a laptop notebook computer has many benefits compared to getting a desktop. A main advantage of opting for a laptop notebook computer over a desktop computer is that a laptop has the ability to be transported from one place to the next. When you run your own small business you will frequently be on the move to meet with new customers. Having constant access to your computer will be extremely important while you are on the move.
I would go with SuperAntiSpyware or MalwareBytes. You can get SuperAntiSpyware by going to atotalnetworksolution.com, then go to the Anti-Spyware page. Free anti-malware products do not keep your computer from getting infected, they clean up after the fact. Paid products do active scanning and keep the machine from getting infected.
No Runescape bot is safe. When you download it, you risk: Your account being banned and/or your computer getting infected with a virus, and ultimately losing your account.
Simply put, no it can't but getting a more powerful one then you need is a complete waste of money. (I'm thinking about watts)
