I have been trying to stop real time scanning from consuming all available cpu and therby slowing down the pc to an unusable level.
I have had Mcafee techs log on at least a couple of times to 'sort it out' but the problem always returns within a couple of weeks (or an update to mcafee).
The only way to make the pc usable is to turn off real time scanning permanently but then you get that irritating message telling you the pc is at risk!
I am almost at the end of my tether with this. Even though my subscription is valid until May next yera, I am going to remove this software really soon unless a permanent fix is available.
Your system specs play a major part in system performance. We've more or less decided (after a lot of discussion in various threads) that the code is optimised to run on multi-core processors with hyperthreading. In other words, older machines are going to struggle to cope unless they've got plenty of RAM. Processor speed is also important, and fast disk I/O definitely helps. Other than that, if you have, say, an XP machine with a P4 processor you have to spend time optimising the system to remove potentially conflicting services and programs if they're not needed; and then do regular housekeeping to minimise system overheads.
So a lot depends on what hardware you've got, and how many programs you've got running on it. One of my PCs is an old Dell with XP, and McAfee runs on it (mostly) just fine. But I see the CPU issue too : just not all the time.
That isn't normal behaviour I assure you.
It's obviously clashing with something else...could be other security software, an infection, your hard drive needs a chkdsk /r perhaps as drive read errors can do this, or you've compressed the hard drive making scans difficult, or are storing many zipped files (or any files for that matter) thereon containing stuff considered a risk....there are dozens of reasons for it.
It could also be because your system needs to be updated...all parts should be always up to date, even those you may not use.
Are there any popups occurring that we should know about or other anomalies?
Without more details it's difficult to give advice really.
Your best bet is to return to Technical Support and escalate the problem.

An additional thought...this isn't a netbook by any chance? They have the kind of processor that really doesn't run well with this software I'm afraid.
As Hayton said above please post your PC specs. I assume this is mcshield using high cpu?

I am running a Dell Inspiron 546: Windows 7 Home Premium 64bit, Athlon 7550 dual core 2.5GHz, 4G ram.
Windows fully up to date, No drive compression, new hard drive recently rebuilt as old disk had a motor fault.(this problem has occured before and after the disk change)
The machine is only used for a bit of browsing , facebook, email etc.
As I said, I've had the mcafee engineers onto the machine a cuople of times and they have run some re-install program. The machine runs ok until , what appears to be, a software update from mcafee. after that, as soon as any program runs (IE, Outlook...) the machine dies. it is the real-time scanning which is killing performance.
Ok not the single core issue as we thought. This dieing when updated is new. Is this update 1 requiring a restart or just a dat update?
Oh can you post your SR job number from their delving into this issue please.

I think there was a restart update but my wife uses the computer more than I do so I cant tell exactly when it happened or if it was sudden or gradual.
the SR details below...
- Service Request #: 943498899
- Created Date: 09/10/2012 10:50:08
- Description: JUST A QUESTION OF PERFORMANCE
An earlier on with the same/similar symptom
- Service Request #: 756591216
- Created Date: 10/18/2011 02:47:23
- Description: The machine is running VERY slow and it appears that mcafee processes are taking most of the cpu. This is happeninig very frequentlyespecially after the machine wakes up or someone logs in
oops, there was another one in between these two
- Service Request #: 886443647
- Created Date: 05/31/2012 05:20:57
- Description: mcshield continually consumes 50-90 of cpu time!
performance of the machine is diabolical
Thanks will ask
What is the version of mcafe you have?
