WannaCry Ransomware Mostly Affected Windows 7

Episode 1388

WannaCry

Last weekend, the WannaCry Ransomware bit several hundred thousand computer systems, including sixteen hospitals in the UK. The ransomware infected the systems and encrypted all data. The reason this one was really bad is that it was a "worm," or a "network aware virus" that would spread out over the local area network to find other computers to infect, and bring the whole establishment to its knees.

Why does Windows 7 keep saying it's preparing to delete files?

Barbara from Los Angeles, CA

Episode 1361

Barbara is getting a message that Windows 7 is preparing to delete her files as soon as she turns on her computer. Leo says that if Barbara has left files in the recycle bin, it may be that when she turns on the computer, it wants to delete the files in the recycle bin because it's full. She should try emptying the recycle bin, assuming she doesn't want anything in it, and then that should solve the popup. If she reboots and the message is still coming up, there could be something wrong with her system.

Do I need to defrag my Windows computer?

Episode 1351

Jane from Manhattan Beach, CA
Windows defrag

Jane has been told to clean up and defrag her desktop every week. Is that correct? Leo says no. It's not necessary to defrag anymore as modern operating systems take care of this on their own. Additionally, for solid state drives, defragmenting is meaningless. Jane also doesn't need to use "CCleaner" to clean up her registry either. In fact, she could make things worse by trying to clean her registry. Sure, she can delete temporary files and clear caches, but all that stuff can be done directly in Windows.

What's a good antivirus for Windows 7?

David from Burbank, CA

Episode 1324

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.
