I'm sorry you felt like the explanation about Clam Sentinel was too much for you. In cases like that, it usually means a bad explanation, so I wish you had mentioned it sooner. Sentinel might be a bit different than most AVs--all configuraltion is done via the little Sentinel shield icon in the Windows system tray. The default items are usually okay to use, so it is just about as "set and forget" as any other AV.
I am pleased to report that Clam Sentinel has been improved since you looked into it. It now has its own heuristic scanner in addition to the original real-time scanner that uses ClamWin. The heuristics enable Sentinel to detect many viruses and other malware for which ClamWin does not yet have a signature. The heuristics are competitive with some of the smaller AV companies, which is a good thing, because Clam AV still has a very small sigmaking staff.
You can download the current version of Sentinel at
http://sourceforge.net/projects/clamsentinel/ on the web. Here are some quick instructions: ClamWin must be installed before you install Sentinel. If you are a new user of Sentinel, you may have to set up your own directory in which to install it. A good directory to use is C:\Program Files\ClamSentinel. If your Sentinel download file is the ClamSentinel.exe file, just download or copy the .exe file to this directory. If your Sentinel download file is a zipped file, unzip the file to this same directory, and then click on the ClamSentinel.exe file. When unzipping, if your unzip program tells you that a file is already in the directory, tell it to replace the old file and all files. During installation, select Run on startup so Sentinel will scan in real-time when your computer starts. Sentinel comes with a Simple Guide you should read after unzipping or putting the installation file in the Sentinel directory but before clickiong on the exe file to install. There is also a file about how you can get maximum protection from Sentinel/ClamWin.
