you can get free antivirus programmes such as Avast or AVG which do a good job. I'd also suggest downloading and running the free version of Malwarebytes, which is a good removal tool http://funadvice.com/r/bgse5ncumm6
Yes you can ... you should be able to get antivirus programs at any computer retailer.
Yes, I would go to best buy and get Avast.
yes you can in stores.
