Hi Friends, I'm new to these forums, although I've been using the free version of ewido (ie - resident shield and automatic updates both disabled) for several months. A week ago I downloaded and installed the new version 4.0. Although I experienced not a single problem with the previous version, it looks like I won't be so lucky with this new one . The last few days I've been having brief freeze-ups of my entire system. I was worried I might have picked up some malware, but thorough security scans (CWShredder, Ad-Aware, Spybot S&D, ewido, Norton AV, and HijackThis) have not detected anything. So I've been attributing it to hot weather, since this is the hottest time of the year, where I live. A couple of security professionals have indicated that a pc running a little too warm can slow a system, and maybe even freeze up briefly. But it's very frustrating, so today, I opened the Task Manager, hoping to find something untoward, which might be tweaked in order to free up more system resources. I don't understand what I'm seeing there, about ewido , and I'm hoping someone here can explain it, and maybe it can be corrected, if it turns out I'm not using ewido properly, or something like that. What I'm seeing is cpu usage of ewido.exe fluctuating almost contantly, while I'm logged on to the internet. It's only between 02 and 05, and every several seconds, it peaks up to 08 to 10. But when I do something else, like open or close a program, save a doc, post a message, etc, which typically uses a lot of cpu, and which happens at the same time ewido spikes, then the cpu gets max'd out, and everything freezes for a few moments. This is happening with the ewido program closed, and with automatic updates, and resident shield both disabled. I never saw this with the previous version. And my experience is that programs which are closed display 00 cpu. Heck, even those that are open and running are usually 00. Watching the running processes in Task Manager for awhile, I see that NO other processes are using as much cpu as ewido.exe is. Occassionally taskmgr.exe jumps to 02, and one of the svchost.exes and explorer.exe jump up to 02 fairly often. But still, ewido.exe is more active than any other process, cpu-wise. When I'm not on the internet, there is no problem. I've done a little searching of these forums, and find a few similar reports. Most are in the Beta forum though, with no solutions offered. And there are a couple of threads in this forum, but the culprit in them is guard.exe, the resident shield, which would be expected with that feature is enabled. But I haven't seen any problems exactly like mine, so I'm thinking it's either something I've done wrong, or something about my system, which is causing this. I'm not sure what info might be helpful, but let's start with this: Intel Pentium 4 - 1.8GHz Hard Drive 37 GB total, 8 GB used, 29 GB free/open RAM 256 MB Windows XP Home SP2 and fully updated Anything else, please just ask, and I'll post whatever is needed. Thank you very much for any help you can offer.
