BalaSGS, thanks for the reply. I had given up on getting a response. I do appreciate it, even though it wasn't the answer I was hoping for. But getting any answer is better than getting no answer. Thanks.
That's really my complaint too. I just assumed it's excessive cpu usage. But I have a web server based app that quite often kicks me out due to slow response during McAfee daily updating. That's why I was hoping there was some way to schedule the process, i.e. to avoid the hassle of being kicked off and not being able to finish my work. I hope some sort of control over the updating process, or improved performance, might be included in future releases.
Like most of you my system grinds to a halt when an up date update is downloaded. So I gave it up as a bad joke as it could take up to 25 minutes to download. So now I have disabled automatic updates and manually check for updates, then I can go away and do something else and I am not sitting infront of computer for half an hour not been able to do anything cause updates are been downloaded.
