John's friend got bit by the popup that said she had a virus and then when she called "Microsoft support" they wanted $300 to fix it. Leo says it's a phishing scam. And once you give someone access to your computer, not only will they not fix anything, but they make the infection even worse by installing other malware. The only way forward now is to backup the data, format the hard drive, and then reinstall Windows.
