Based on this text, here are some key points comparing McAfee's antivirus software with other options like Bitdefender:

1. Both McAfee and Bitdefider allow for scheduled scans at convenient times when the computer isn't in use.

2. While both can still be used during scanning, heavy tasks such as gaming or streaming videos may not be possible due to system resource usage by these full system scans which typically take around an hour each regardless of whether you are using your PC or not!

3. McAfee uses traditional malware detection techniques including checking files against a huge virus database and identifying potentially dangerous ones through heuristics, similar to how Bitdefender operates.

4. Both software packages performed equally well in detecting 100% of the tested malware samples, indicating that they offer comparable protection capabilities.

5. Regarding system performance impact during scans, McAfee caused some noticeable slowdown compared to Bitdefender's lightweight approach which barely affected overall computer speed even when running resource-intensive tasks simultaneously without significant lagging issues arising from its operation.

6. Both antivirus software packages provide excellent real-time protection against malware threats through their respective features like 'Bitdefender Shield' in the case of McAfee, effectively blocking malicious downloads before they can execute on your system.
