Recently, I tried to run an update in the background, and as usual (>=50% of the time), Mcafee locked up on shutdown. However, on using a hard reset, Mcafee started having problems...so I uninstalled it and re-installed it from the original CD and updated it. I also did the full load of updates via Microsoft Update so there wouldn't be any problems.
My problem is that the real-time scanner is running on one of my video games (Star Wars Empire At War: Forces of Corruption) when it has no business doing so, and didn't before this total reload of the McAfee software. Having run McAfee Virtual Technician and come up with no errors, I can only assume that the most recent set of updates is to blame - nothing else has changed on my computer.
What happens is when I double-click on the icon to start the program, I get an hourglass icon for a mouse cursor, and it sits there...forever. Invoking the Task Manager program, I see immediately that the On-Demand Scanner Service (mcshield.exe) is running at 25% constantly. It shouldn't be running at all...the program is installed directly on the hard drive. On disabling real-time scanning through the McAfee program, the problem disappears and my game runs as before the recent updates. Prior to the recent updates, I didn't have to turn off McAfee in any way to get my games to run. Hopefully you can fix this.
On the topic of fixes, I would also like to complain about McAfee becoming extremely bloated in the 2010 version as compared to 2009. It runs too slow, and it takes my CD drive approximately 15 seconds just to do an auto-run anymore. I don't have the detailed logs of the previous version, and several features disappeared completely. The software also does too many large communications across the Internet while I am running my other programs (mostly high-performance games), which sometimes causes crashes. This didn't happen in the 2009 version, which is why I bought it in the first place. I'm seriously starting to have second and third thoughts about using this software. I yearn for the days when all I needed was just to update the DAT files and avoid the engine updates - this new interface SUCKS. Period. Updates are about adding more features, not taking them away; making the software easier to use, not harder and more obfuscated.
I hope 2011 will bring about a better core UI and all of the features back from 2009, and the slowness removed.
