What's a good antivirus for Windows 7?

Episode 1324

David from Burbank, CA

David is trying to find an antivirus for Windows 7. Leo says that Microsoft's own Security Essentials (or Defender, depending on the version) is sufficient, and it's free. The problem is that viruses are usually coming out so fast (called zero day exploits) that you can get infected before the AntiVirus finds it and removes it. Then the viruses are often attached to a system file and it renders the computer unusable. Even security experts put antivirus low on the list of things to do to prevent infection.

Episode 1319

Tim from LaHabra, CA

Tim has a message popping up that asks which app to open a file with. It happens automatically and he doesn't know what file it is. Leo says that's disconcerting. Leo suspects AdWare or worse! There's something on his system that is running in the background and the antivirus can't kill it. He'll have to figure out what the app is that's starting up. He'll have to expect that his system has been compromised, though, and the only real way to be sure he's gotten rid of the malware is to backup his data, wipe his hard drive, and reinstall Windows.

Rich from Placerville, CA

Rich wants to know if Webroot is a good antivirus utility. Leo says that Webroot is good, and they're a sponsor. They offer additional protections because they're cloud based. But he really doesn't need it. Windows has its own antivirus called Defender that's quite good. Also, the state of malware is such that most occur as 'zero day exploits' which an antivirus can't catch. But Webroot will protect him for the most part. He should remember that his number one defense is his online behavior.

That will take it out of full screen mode. At that point, she should be able to close it. CTRL-ALT-Delete will work as well.
