I am helping someone who received an older computer with Windows XP installed. They did not realize that McAfee was installed and installed Avast also. The computer now locks up on boot. How do I get into the PC and remove McAfee…
They did not realize that McAfee was installed and installed Avast also.hmmm....and Your topic title say AVG ... ???
well… can you start in safe mode? … if so try uninstall from safe mode
if success …then you need to run removal Tools for all AV removed so that all leftover files that may conflict is gone
Tools found her http://singularlabs.com/uninstallers/security-software/
Sounds like the title should read ‘multiple Avs installed’.
