Bill has had a problem with a popup saying he needs to update his Flash. Leo says that's a phishing scam designed to get him to install Malware. Luckily, Windows Defender usually sees it and removes it because it's an old tactic. But if it didn't, it may be really difficult to get rid of the malware. Usually, the best thing to do is backup his data, format the hard drive, and then reinstall and update Windows. Never accept gifts from strangers. He shouldn't download from someone he doesn't know. He should always go directly to the source if he thinks he needs to update something. And in this case, that would be Adobe Flash.
