I had Alpine clean off viruses. It took three weeks. They were still there when I got home. I took it back. I waited two weeks for them to call me. I had to call them. I picked up the computer. They said I needed a new hard drive, etc., for $285. I took it to a reputably known business. They said I did not need new hard drive and cleaned off the viruses for $75. My computer works fine now.
