"...Intel initially issued a big file (100MB) that you had to download, but at least it upgraded everything on your machine, if it needed upgrades. After rebooting in the next few days I noticed that my machine is a bit slower then it was. A look at Task manager output, or excellent Process Explorer from Sysinternals showed that a process called S24EvMON.exe is using quite a bit of CPU... Dell... released their own version of drivers... Dell's drivers have the same problem... It looks that everyone with (at least) 2915ABG/2200BG wireless cards is affected. F-secure posted this in their weblog as well* ...
UPDATE:
The easiest way to start and stop these services (so you actually run them only when you really need them) is to create a batch file that will do this job for you (so you don't have to click manually on all 4 of them). You can use the sc start <service name> and sc stop <service name> commands to perform this for you...
UPDATE 2:
..You can use the built-in Windows Wireless Zero Config service, in which case you only need to patch the driver for your wireless card, so you are not vulnerable. As the problem with CPU/memory leaks are in the management service, this is an effective workaround at least until the management service is fixed..."

"...We noticed that software (S24EvMON.exe) installed with the driver seems to be leaky. It's eating tons of file handles and tons of memory - and it continues to grow!... Intel's tech support has replied. They are aware of the issue and are currently at work on it. No official release date yet. We'll let you know."
