Security researchers have identified performance problems with a recent wireless driver security update from Intel. Vulnerabilities in Centrino device drivers for Windows and Intel's PROSet management software prompted a security update three weeks ago.
The initial update weighed in at more than 100MB, though Intel did produce a slimmed-down update
Unfortunately, software installed (S24EvMON.exe) with this Wi-Fi driver is leaky, consuming considerable CPU and memory resources and thereby hitting on the performance of PCs with the software installed, researchers at net security firm F-Secure have discovered
Although the performance hit is undesirable, leaving systems unpatched is even more of a problem. The SANS Institute has put together an advisory
