Any reason why you can't do the updates in the non-business hours?<br />
I always used to schedule all of the AV and MS updates in the middle of the night - and the scans to get that out of the way before everyone showed up for work.

I have patch 5 but it seems to have same problem...

<div>
<div class="content wysiwyg-content">
We are running VirusScan Enterprise 8.5.0.i, Scan Engine 5200-2160. Some of the workstations have been patched to revision 5. &nbsp;Although, many have not been patched at all.<br />
<br />
Immediately after the daily dat file update, the process mcupdate.exe spikes the CPU to 100%. PCs which have not been patched to revision 5; the PC becomes unusable for 5-20 minutes. &nbsp;The same PCs after they have been patched to revision 5 behave some what better. &nbsp;The update still spikes the CPU to 100% usage but lasting only about 3-5 minutes. &nbsp;Towards the end of this 3-5 minute spike, the CPU usage will drop some and the PC will be somewhat usable.<br />
<br />
Approximately 25% of our PCs are experiencing this high PC utilization. The remainder of the PCs run the update without problem.<br />

McAfee Update Causes 100% CPU Utilization

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.
