Recently I updated to CIS to 3.13 and all was well for a while until a recent auto update. From that time on PC start times, program loads and opening files has slowed dramatically. ‘cmdagent’ hogs processor time typically always above 80% at program load and 30 - 40% even at idle. I have tried the ‘fix’ with replacing bases.cav as COMOD instruction below:
Because of an issue with the latest virus database, some computers might
observe significant CPU consumption problems caused by cmdagent.exe.
You might observe this issue if your virus database version is 2525 and
later. We have reverted the problematic updates. However, because of the
nature of this issue, already affected computers might not function properly
to revert the updates back.
For those computers, the following instructions can remediate the issue:
1 - Reboot your computer in safe mode
To enter to the safe mode, you need to press F8 button before Windows starts
booting until you see the boot menu. In the boot menu, select the safe mode.
2 - Delete the file in c:\program files\comodo\comodo internet
3 - Copy c:\program files\comodo\comodo internet security\repair\bases.cav
to c:\program files\comodo\comodo internet security\scanners folder(this
action will replace the current bases.cav file with the original bases.cav
file that comes with the installation).
4 - Restart your computer and Update your virus database again.
After these 4 steps, everything should go back to normal.
Alternatively, you can manually download the latest bases.cav file from
and replace the problematic bases.cav with this version.
We are sorry for the inconvenience this might have caused.
After trying the above fix and loading Update_Bases_User_v2456.cav things went back to normal. However, this week after the Auto update the PC has slowed again.
My version of CIS: 3.13.121240.574
Current Virus Data Base: 3381
Would appreciate some help in this.
