FAQs

My Mac is running slowly. Could this be due to malware, even if I don't see any obvious signs?
Yes, malware can significantly slow down your Mac even without visible symptoms. It often runs in the background, consuming resources. A deep clean, including removing unnecessary files and running a scan with reputable anti-malware software, can resolve performance issues.
I've scanned my Mac with built-in security tools and found nothing. Do I still need a deep clean?
While macOS has built-in security, it's not a complete solution. A deep clean involves more thorough checks and removal of potentially harmful files and processes that might be missed by basic scans. It's recommended for preventative maintenance and optimal security.
