Hello and welcome to our forum.
Please allow me to inform you that BullGuard has a 30 day money back guarantee, for any purchase made on our site. Refunding your order is not an issue.
However, having these issues means that your computer could be infected, it could be damaged or could have other conflicting software. Since we offer free support for our users, apart from the refund, I also recommend that you try our Live Chat and ask for assistance.
Cheers!
