Processes using high amounts of CPU and RAM

So we have McAfee AntiVirus Enterprise 8.5 managed by EPO on our network. It's really a great product. The only thing that seems to present a problem is that the Virus Scan Task Manager (VsTskMgr.exe) seems to constantly hover between using 5% and 17% of the CPU and can use upwards to 250MB of RAM. The On-Acess Scanner (McShield.exe) varies widely but can spike using the CPU and RAM as well. The On-Access Scanner acts somewhat like I would expect it to, however it does seem abnormaly CPU intensive at times. However, the Task Manager seems unordinarily active using CPU constantly. Does anyone else have the same problems and does anyone have any advice on tweaking anything to make these processes behave in what I believe should be a more stable manner?

    Accepted Solution

    This isn't entirely unusual.  Depending on how you have configured scanning for the AV (ie. scan all files,  heuristics scanning, etc) and the number of open/closed/active files and processes, it can become resource-intensive.

    McAfee VirusScan is, in comparison to the other popular AV solutions on the market, considered very resource-intensive and the rates you specified is not surprising.  You can cut down resource use by reconfiguring the scanner settings to be less scrutinous, however be very careful when doing so as the level of protection provided can diminish.
