Solved - An error occured in avast! engine: Invalid argument.
I really should remember to check my LJ configuration tag when I can't remember how I fixed stuff in previous installs.
I should also remember to record those little fixes, like this one for avast! antivirus:

If you have installed Avast on your Ubuntu Operating system. Once you have updated it, you will get an error, An error occurred in avast! engine: Invalid argument. In order to solve this error, all you have to do is the following,
Alternatively, you can run this command from Terminal as well, but you would have to do it every time you start your computer. So instead, it’s a better idea to make the change in the sysctl.conf file. Here is the Terminal command,
sudo sysctl -w kernel.shmmax=128000000
kernel.shmmax = 128000000
(Per my browser history, I originally found this fix in http://forum.avast.com/index.php?topic=57812.0, but they're down right now, and this other page was available.)
Also, do not do weird shit to configure xscreensaver under KDE. Just install it, and after rebooting the modules should be available in System Settings -> Hardware -> Display and Monitor -> Screen Saver -> Miscellaneous -> Clock. If all else fails, install Clock screensaver for GNOME. However, comma, you still need to go to System Settings -> Hardware -> Power Management -> Energy Saving Settings -> On AC Power tab, and uncheck Screen Energy Saving. (Switch screen off when AC power is on? Really, Ubuntu? Really???)
