My computer will not open certain programs, and the system does not.

I have really no idea what's wrong with my computer, so I'll just list the symptoms.

The first and foremost problem is that my computer won't open some programs.  First thing I noticed when I tried to open iTunes and it did not open, no matter how many times I tried.  I went to restart my computer, and that opens up a host of new questions.

My antivirus - Windows Live OneCare - software does not open.  I tried to turn on Windows Defender for malware, but it crashes when I try to do.  Not only does iTunes opens, but neither a few other programs I have on my computer--mainly those who could help me to solve this problem, such as the restoration of the system.  When I try to uninstall a program - all - nothing happens and he refuses to let me try to uninstall anything else, insisting something is already uninstall.  And my computer can't detect my printer.

Which leads to my other problem: I have two computers connected to a network via an Ethernet cable.  The other computer is fine and can access the Internet fine, but when he sends something to the printer, nothing happens on the end of the printer.  It is a red 'X' the symbol of my network on my computer in the lower right corner (next to), so I guess this confirms my concerns about the network.  I don't understand what exactly is the problem, just that the other computer cannot print (it is not connected directly to the printer, mine is).

Because Windows Live OneCare and Windows Defender does not work, I can not scan to see if it is the result of spyware or malware.  And because whenever I click on the system restore, nothing happens, I can't restore the computers to something else.  I'm completely stuck.  More critical functions simply do not work.

If you have Vista then the Windows 7 upgrade that will take and install without problems, but the editions between operating systems need to be adapted, Home Premium, Home Premium edition, or higher, you cannot switch to a lower version.
