Will only boot in safe mode

I have a HP laptop which is running Vista. My kids were using it this morning and clicked on a pop up banner. When this happened a number of pop-up windows came up saying i had a virus and needed to click them to scan the PC.
I tried restarting the computer but all that happens is I get a black screen with the Microsoft corporation logo and the green 'knightrider' style banner.
I can boot it in safe mode and that is okay.
I have run startup repair and it says that it cant repair the fault
I have also tried system restore but it say there are no restore points

Can anyone help - would be gateful for any help/advice

Thanks

 

bugger,
sounds like you might need to reinstall windows, if so think about geting win7 as it has all the features of vista but is nowhere near as resource intencive.

you could try:

Repair from the install disk
running your virus scanner in safe mode
performing updates in safe mode

hope this helps

 

Boot into safe mode like you did and install mbam.

Run a full scan and remove all infected items, then restart and you should be golden...
