Anti-Virus Basics

This section will bring me some heat, because a lot of people in the security community don't believe that anti-virus is helpful. I disagree, mostly on the basis that while they only detect lowest hanging fruit malware, I don't want to be a lowest hanging fruit victim.

Basically, these companies execute the malware, break down the malware into tiny pieces and creates indicators for the different components and what the execution of them look like, so that they can identify them on your computer and completely delete them off. I recommend that you have Windows Defender running at all times for protection. There is no need to have any other anti-virus on your computer, more is not better. As an important note, Linux anti-virus is pretty horrible and you should never install it. It's pretty difficult to get a virus on Linux, but if you do, let me know so I can RE it.

The only time I'd recommend you run a second antivirus is to remove an active adware or PUP infection as Windows Defender doesn't consider many of them malicious.

Task:

1. Read this: https://www.computerhope.com/issues/ch001738.htm
2. Download Malwarebytes and run it. https://www.malwarebytes.com/mwb-download/
3. Install Windows Defender, because it is built into your computer and really, really good. If it is installed, make sure it is running.
4. Uninstall Malwarebytes. You don't need it around all the time, just download an run it whenever you get on a new computer and then once every couple months just to make sure.
