Recently, I think since last week, my Windows started to experience significantly slower startups. After some investigation, I've now traced this problem to McAfee Real-Time Scanning. After changing the settings in Virus and Spyware Protection > Real-Time Scanning > Startup Settings, from the default "Check for the most common threats during startup, for a fast startup time." to "Check for all known threats after startup, for the fastest startup time.", I can again have a fast Windows startup that I've long enjoyed since the day I bought this computer.
I am using Windows 7 Pro SP1 64bit with all latest updates applied
I've ruled out hardware performance issues as my machine has 8Gb of RAM, Core i7 CPU @1.73GHz and more than 300GB of free space.
Also, I need to point out that this happened out of the blue with no major software changes to my computer before and after. No new programs were installed, no modifications were done either, no major software updates (except McAfee I guess) and no hardware changes.
I thought I can just modify the settings and leave it be, but no, McAfee had to reset the settings back to default after some time, which is a very naughty and virus-like behaviour. So now, I have to change the RTS settings every time I shut down the computer to ensure I have a fast startup next time, which is kind of annoying. I've ran several tests for malware and viruses and everything shows up clean.
I suspect an update to McAfee caused the longer than usual startup for Windows behaviour. Also, is this by design that McAfee RTS resets its settings? I noticed that it does not reset settings right away after a new reboot, not even after autoupdating or me forcing an update scan, but rather randomly and quietly/secretly after some time using the computer. But it eventually will reset the settings to default (the setting in question here is the Startup settings ONLY). I've known of this behaviour since McAfee changed its layout to the current one, which is quite a long time ago, but I ignored it since it did not affect me in the past. But now, if RTS is going to slowdown my startup, I really want the Startup settings I MODIFIED to STAY.
I hope the techs and mods can help me escalate this to the highest support. I am also tired of opening a ticket and running the usual diagnostics or even allowing McAfee techs to take control of my machine. I believe anyone with McAfee SC installed can just test it and will know that the changes to Startup settings CANNOT stay as it will just revert back to default sometime soon.
So, in a nutshell, I have TWO things to report here:
1) McAfee RTS slowing down Windows startup significantly or taking a longer time to load.
2) Changes to McAfee RTS startup settings cannot stay for long. (This is a very old problem which many ignored)

Thanks in advance to anyone who would help out. Seriously, McAfee needs to take a serious look at how RTS is behaving as I've had TWO major disappointments with RTS since. One has since being solved, of which RTS consumed too much CPU resources when running games through Steam, and now this.
