On Tuesday I experienced a problem with my Wifi. I couldn't connect and got the yellow alert triangle on my wifi signal even when all the signal bars were full. My roommate wasn't having any issues that I was having and could connect to the internet fine, so I determined it was a problem with my own computer.

I managed to download Microsoft Support Emergency Response Tool when the internet briefly resurfaced, which detected 54 infected files. From there I uninstalled my previous antivirus, McAfee, and installed Windows Security Essentials yes, I found out in hindsight that I should not install things when I'm having virus issues. Windows Security Essentials found an additional 14 viruses, most of them Trojans. I downloaded Malwarebytes and found nothing.I recently bought a MacBook Pro and was using it fine for a while until I ran into a major problem that I can only guess is caused by malware.

Certainly doesn't sound like any Mac malware that I know of. It's possible your router has been hacked though. Just because you are connected by WiFi or Ethernet to your Router does not mean you can connect to the Internet. That may give you some clues as to what's gone wrong. Sometimes is as easy to fix as unplugging your modem for 30 seconds or so, plug it back in and wait for the lights to signal your connected.

I also would like to know if there is a way to install malwarebytes without having an internet connection as I have tried to do so before and was not able to.

I know it's not possible to update the database without Internet connectivity and I can see from examining the installer that it comes with an empty database, so there is no way to detect anything. The Diagnostic should have given you some clues on what to check. Since other devices on your local network are working fine, then it must be something on your computer. Did you check to see if your DNS settings have been changed? I removed the diagnostics file from your post, since it may reveal personal information you don't want shared.

I see some signs in your diagnostics file that your computer was able to connect to an Apple server successfully, so it doesn't look like it's a universal issue. Is this only affecting a particular app? Well I have tried to open every app that I could and none of them think they have internet access.

If you're having the same problem in safe mode, then whatever the cause of the problem is, it's not third-party software, including malware.

It's a configuration issue somewhere, probably on your Mac, but I'm not sure what that might be. Since the network connections done in the diagnostics were to raw IP addresses, that could mean that the problem is with your DNS settings, and the problem isn't with the network connection itself, but rather is with the ability to look up IP addresses for domain names.

Okay, thank you. There has been malware that has been known to change network settings. It's not particularly common, but it has happened.
