Have pc xp3 Gigabyte mobo using avast free basic setup 10.3.2223
Yesterday had program update and required reboot . Pc rebooted but blank screen.Several manual reboots later accessed windows startup.
Pc slow and sluggish so after several hours use decided to uninstall Avast free and reinstall. Boot up failed. Could not use optical drive or access boot options or bios settings. Only got splash screen for mobo and then blank screen.
Eventually powered off pc drained residual charge by keeping power off and switching power button on.
Rebooted fine but with several security window updates previously installed.
Q. Did update/uninstall effect my CMOS/BIOS and why?
Do I use Avast again?
