Can't boot up Vista - Possible virus attack?!

  natbates78 11:50 16 Jul 2009

Hi, I've made a bit of a mess of my computer and now don't know what to do. It won't start up properly at all now. It's a Packard Bell, about 1 1/2 years old, operating on Vista Basic Home Edition.
Basically, I downloaded a film that I think was dodgy (no, not in that way!) and now it's caused me all sorts of problems and I'm worried I may have lost everything on my hard drive. After I realised the film was no good, I deleted it and thought I better run a quick virus scan, just in case. I use AVG for this. I started the scan and walked away but a minute or two later I heard the pc 'pip' as if it was turning itself back on. Then I got the black and white screen and just two options ; 'Start Windows Normally' and 'Start Windows Recovery'. I tried to start normally but after the splash screen, the screen just stays black and nothing happens. Then I turned off/on and tried the 'Windows Recovery' option. From the menu within this option, I took the ioption to go back to a restore point, which involved several scans to fix any problems first (which lasted about 45 mins). The scans said that they could find nothing wrong with the system but it still wouldn't start from the last restore point. I also tried other options in this menu, such as letting the Windows recover try to fix files etc. but still no good. When I start the computer, I still just get the two options, both of which seem a bit futile now.
Is it worth trying to start the system in Safe Mode (even though at the moment it's not giving me this option on startup) and doing anything from there, if I can? I'm definitely no PC expert but I don't really no what to try next. Have I lost everything on my PC???

If you think it's a virus that is preventing you from booting, try the Linux Avira Antivir Rescue system, click here

Do your system restore in safe mode it should work ok in there.

Start into SAFE MODE

1/As your computer starts but before Windows launches, press F8 repeatedly.
2/Use the arrow keys to highlight Safe Mode, and then press ENTER.
3/If you have a dual-boot or multiple-boot system, choose the installation that you need to access using the arrow keys, and then press ENTER.
Note: If Windows launches before you can choose a safe mode, restart your computer and try again
PS/ Sometimes it maybe the F5 key

I've tried to start in Safe Mode but after I choose this option, it shows the loading bits, then the screen is just blank with the cursor on. I've tried all Safe Mode options, with Command Prompt etc. but it's the same each time.
