Rainbow said:I have Windows Defender in my ASUS pc notebook. Do I really need the McAfee security system?
Windows Defender is a full anti-virus program, at least on Windows 8+. You really don't need another anti-virus program, if you're satisfied with Windows Defender's protection. However, I do recommend you supplement your anti-virus with an anti-malware program such as Malwarebytes Anti-Malware (Premium). Anti-Malware programs focus on adware, toolbars, browser hijackers, potentially unwanted programs (PUPs), and potentially unsafe applications. It is more likely you encounter these today.

If you cannot completely uninstall McAfee, because it's corrupted, consider using their Consumer Products Removal tool:

P.S. Never run two anti-viruses at the same time!
