If you've recently purchased CA Security Suite to handle your AntiVirus and AntiSpyware needs, then you should check the software carefully to make sure everything installed correctly.
One of my clients recently purchased the 2009 version of CA Security Suite and had several problems getting the software installed properly. Things appeared to work okay, but following installation there were several errors and they were not able to "secure all" the items listed.
Several attempts to uninstall and reinstall the software did not fix the problem. Turns out there is a known issue (or software corruption) with the firewall portion of the software that was causing all the casc.exe errors.
After chatting online with CA tech support for a couple of hours, it they directed me to a link where I could download a good version of the software. However, in order for that installation to work, CA tech support had to first run their removal tool remotely to remove all trace elements of the previous installation. Without doing this, the 'fix' won't work.
The easiest way to talk to CA tech support is through their online chat support (that way you don't have to deal with heavy accents when talking to folks in India) and they can easily connect to your computer remotely to run the removal tool.
Once you're CA Security Suite subscription is up, I'd highly recommend switching to Norton Internet Security!
