every few days CIS completely takes over the CPU and RAM. There is no way to work on the computer, even watching a movie does not work. I have to save all my files and restart the computer.
Please help me to turn of this behavior. If there is something big to cache or update CIS should ask, if i can interrupt my work at the time, or when it should ask again. Just to take over the computer is very unprofessional.
Scheduled scans were not disabled, but i think there was no scan, since i did not notice it on the main CIS interface at the time CPU was blocked. I think the performance problem was the installation of new signatures in the background, but i will disable the scheduled scans too.
I do not use another antimalware-software. The computer is nearly clean of additional software. Only Windows XP + Firefox, Thunderbird and Media Player Classic (all as Portable-Versions)
The box for software updates is grayed out because the option above is already disabled. Thus, it is disabled as well.
Please disable the scheduled scans, just to rule out any possibility of this being what caused the update. Then, if the AV updates again without you explicitly doing it, I think it would be worth creating a bug report for this. I can’t think of why it would update with that checkbox unchecked.
Also, did there used to be any other anti-malware software which used to be installed but is now removed?
I’m a new CIS Premium user and also encounter this problem. System is an up-to-date new-install XP in a VBox 4.3 VM assigned 768MB memory and one CPU on a OS X Macbook host. CIS is v7, auto-updated from a v6.3 install, just a few UI settings changed, others unchanged from defaults.
System was allowed to auto-update database after a boot, usually after a few minutes. CIS update window says signature install stays at 90% for a long time, well over a minute. During this time, the cavwp.exe process CPU and memory cycles up and down several times. On one cycle it’s up to nearly 500MB (out of 768) memory usage and over 80% CPU, other cycles usually max about 300MB, also 80-90% CPU. After about four or five cycles it finally dies down and the signature install is complete.
Initialization of bases begins with 90% after loading of updating of bases.
At Initialization a bases of the CPU gives big % loading.
But not there is a lot of as at you, at least in old versions.
I believe that at you it is connected with a caching option.
Try it to disconnect - Run cache builder
Edit: I looked at 5 versions.
CPU From 30 - 70% ( Initialization of bases )
Thanks. I disabled the idle cache builder, forced an update, but got the same result. Cycles of up to 500MB memory and 90% CPU in cavwp.exe. That makes sense as the idle cache builder is only active when idle, and a database initialization is not idle.
Suggest you re-create the VM XP system described above. Lots of XP customers may come your way for single-source combined AV and FW after MS ends XP support, so it may be worth your while to do so. That’s why I’m looking at it.
I hope it 's not something simple like resorting a combination of two already sorted lists, instead of sequentially going through both lists to create the sorted combination. That O(N) rather than O(N*log(N)), or worse O(N^2).
