The simple reboot that Kappy suggested seemed to work guys (thanks Kap!). It kept logging even after I uninstalled avast!, but after the reboot, no more logs. On another note, anyone familiar with the bootloader warning? The file it was warning me about was a ".dmg", and depending on where I was searching, some people said that "all .dmg files are downloaded and if its bootloader.dmg then it's a virus or malware" but I've seen some that say it's harmless and an factory-installed part of OS X. Can anyone shed some light? I'm fairly new to mac, and I worry sometimes about my computer's safety.
