Hi @eden2,
We apologize for the inconvenience.
There may be multiple reason for the device to act unexpectedly. Below are few reasons mentioned.
- Running out of RAM (Random Access Memory)
- Running out of disk drive space (HDD or SSD)
- Old or fragmented hard drive.
- Too many background programs.
- Too many startup programs.
- Falling behind on system OS updates or driver updates.
- Malware or viruses.
To check if your computer could be infected with malwares or viruses, you can run a scan with McAfee.
If you would like to switch to another AV, then it is recommended to remove the previous one as it might make your device very slow.
For removing McAfee you may follow the steps mentioned in the below McAfee article
