Yes you're right Some third-party applications will not allow McAfee software to install or run correctly. To ensure your computer is functioning efficiently with McAfee software, we have to uninstall them.
But as we mentioned only Some third-party applications Not all of them you can use the program but in case if you have any issues then you have to remove any one of them.

As long as it doesn't have an antivirus component it shouldn't clash. However, I would beware of any registry cleaner and/or optimizer as eventually essential registry keys get cleaned up along with the trash and then software/system malfunctions can occur.
I'm not saying this is definitely going to happen but I've seen so many cases of it with any of the registry cleaners available today, that I thought that I should mention it.
If your system is short on resources and you feel you need more 'elbow room' then it's far better to increase those resources if possible, i.e. more memory, larger hard drive etc.
Windows does it's own cleanups at regular intervals and you always have the tools available in Control Panel/System and Maintenance.
Thank you for your replies. The ASC3 has got Spyware defense - but that's it. Going on what you've said I think I'm going to take a risk as I like both programs. ASC3 has a restore center to roll back any unwanted changes - so I think I'll be OK. But be sure - if anything does happen I'll be sure to come back here and let you know so that other users don't make the same mistake!
