When your lappy boots up, hit the F8 key once (or like me, as many times as possible so you don't miss it). Choose 'Safe Mode with networking' so you can connect to the internet. It'll look like blocky nonsense but it's safe. Then get on the internet and go to
www.malwarebytes.org/mbam.php and download the program. Install it, but don't run it yet.
Next go to
http://www.superantispyware.com/download.html and download the free edition. Install that program and then run it. Once it's done, remove whatever you can and then run malwarebytes' program.
Once that's done, remove everything and then invest in ZoneAlarm for a good, free firewall (
http://www.zonealarm.com/security/en-us/anti-virus-spyware-free-download.htm, go for the basic firewall).
It might be a pain initially as you give permissions to all the programs that need the internet, but it'll save a headache later on.
Alternatively
If you can't get on the internet with option A, choose 'Safe mode' on it's own then download the above programs on a 'puter with a CD burner and burn the programs onto a spare CD. Then follow the steps above.
Alternatively Alternatively....
If you still can't get past the startup screen, you have a corrupt MBR (master boot record) and it needs some serious fixin. If you're not sure about how to go about it, I'd recommend a good repair shop that knows their stuff.
