computer help: I am not sure if this is the right site to go to for this kind of help. - Help.com

Hmm
I take it you have tried holding the power button down for a miute to do a quick power off? (note: you should only turn off your computer that when if there is no other option)

If it still starts up the same then I think you need to get an adult to look at it.

If it starts up fine then you need to go into, programmes, control pannel, add/remove and the uninstal what you put on there.
Once you manage that you can instal either AVG or Avira, both are free and both are good legit anti virus programmes, make sure you get them from a legit site though and not just from an ad or something.

No worries, let me know how it goes and if that didn’t work then we can see what else I can think of :)

If you’ve already got a load of viruses on your computer, the only answer may be to reformat the hard drive. This will wipe everything off the drive, viruses and all, and will mean you’ll have to reinstall windows (and whatever else you had on there). If you have to resort to this, make sure you have an afternoon free because you will need it.
