Re: Baidu Antivirus 2013 (Beta) I'm at work, and can't check now, but I do not think they are in the cloud. The old Kingsoft AV used to have peak memory of about 55meg. This version gets up to about 250meg. It seems after updates, it normally gets up to about 135meg. Then over the next hour or so settles back down to 10-30meg. I have not had enough time to monitor CPU use, but disk I/O seems a bit higher than the old Kingsoft program also.
