I experience fast battery drain on my hp 250g8. I do not face the same problem with another antivirus.
I use trend micro and another antivirus on and off(both are paid subscription).
I do not face the same problem with the other av.
n.b.- I keep my windows 11 updated with the latest version. I always install the latest montly update as soon as they arrive on second tuesdays every month. I have never installed any preview updates on my laptop
I do not think of installing tm or renewing my tm subscription ever again unless you resolve all the bugs.
do not ask me for log files or version no. because I already uninstalled tm. I am thinking of installing tm few months later. I expect not get any problem with tm then.
