Any of the virus scanners in our list are good, but there is also AVG from Grisoft.com. As for malware scanner, my new favorite tool is Malwarebytes' Anti-Malware.
As for malware scanner covering virus scanners, there is some overlap but there is need for separate tools.
Once you are ready to remove your McAfee install, go ahead and uninstall it and then run the The McAfee Removal Tool, available
here.
Then I need you to reboot windows cleanly. To do that please go to the run command and type in msconfig . Once that starts, select
selective startup, and then uncheck the
load startup items. Now click on the
services tab, and down near the bottom of the window, check the box that says
Hide all Microsoft Services now go up and uncheck all the services still listed, make sure you scroll down the list if need to unselect all the non Microsoft services. Now click
apply, then click
OK and reboot the computer.
See if your computer boots faster. Once you have decided that, run msconfig and select normal startup then click apply then OK and reboot the computer.
Let me know how it goes.
