FAQ
Q1: Can Macs get viruses?
A: Yes, though less common than Windows. Mac-targeted malware is growing, especially bundled with pirated software. Run antivirus anyway.
Q2: Will virus removal delete my files?
A: No — proper removal doesn't touch your data. We back up important files before deep cleaning, just in case.
Q3: Can ransomware be decrypted?
A: Depends. Some older strains have free decryptors; newer ones are tough. We'll assess first — no recovery, no fee. Back up regularly!
Q4: Which antivirus do you recommend?
A: Windows Defender (built-in) is honestly enough. Keep the system updated, don't click suspicious links or attachments.
