I don't know what Quilt TV is, is it one of the pay sites like Alex Anderson's? I so wish they had quilt shows on regular TV like they used to.
I do know about Malware, it's especially ugly. When you get that screen that says you have a virus, that is the virus. They will offer to clean your computer for a fee, often they just take your money. When it happened to me I lost all control of my computer. I used a different computer to get online and downloaded malwarebytes which cleaned everything up. Now I keep that on a disc, not just on my computer. Everyone should keep something like that handy. I'm not running an ad for malwarebytes, that's just what worked for me. If you do want to try it, it's .org not .com. Be careful.
