does using a decent cooling pad helps the problem?
Your CPU is safe at temps up to 100°C and while using a good quality fan type cooling pad will help with keeping temperatures down it will not help with high memory usage.
Things of note in your Speccy report;
Power Profile
Active power scheme: High performance This should be set to Balanced as high performance generates more heat, can cause instability and shorten the lifetime of the battery and other hardware.
Hibernation: Enabled Known to cause issues, is not of much use and should be disabled "how to" below;
Open the Win+X menu, and click/tap on Command Prompt (Admin)
In the elevated command prompt type powercfg -h off press Enter and you are done.
McAfee Security Scan Component Host Service is present on your computer, did you install this, regardless, uninstall it so that it cannot conflict with Avira.
Scheduler
All of the following are scheduled updates for your computer, other than Windows and your AV protection nothing should be set to update, this frees up system resources and avoids any potentially bad updates from being installed, HP updater is an odd one as no HP printer is detected by Speccy.
