Some Services Not Starting?

Today, my computer just finished installing updates, and was waiting for me at the user selection/log in screen when I checked on it. I powered it off by holding the power button down to change some BIOS settings. (In the end, I did not save any changes to the BIOS, so I can rule that out) After rebooting and logging in, MSE and avast both tell me that their respective services have been stopped, and WiFi is not working either (its stuck as connected, but has the small yellow triangle in the icon, it says its identifying, but its been stuck like that). Other services, such as Dropbox and RocketDock have also been stopped on my computer.I then rebooted into Safe Mode with Networking. WiFi is still not working, and now, audio service is also stopped. From here, I uninstalled all of the updates that had been installed today. I then rebooted normally.Finally, RocketDock and Audio Service are running again, avast!, MSE, Dropbox, and WiFi are not still. I'm using Malwarebytes' and avast! to scan for crap that might be doing stuff (Malwarebytes' has already picked up four positives, both scans are still underway).
