McAfee Security Center Corrupted
I have a few questions I hope someone can help me with. My McAfee Security Center appers to be "jinked" and and I cannot reinstall my McAfee as prompted to by my PC. The McAfee was installed by Dell and on Vista there does not appear to be a way to uninstall it.
1) It appears to be McAfee 7.1. Is this all I need to know if I go to Wal-Mart to get one? Often their sales people know about as much as I do.
2) Do I nees to uninstall the old McAfee before loading the new?
Thanks for any help.
