| Aspect | PC Software | Mobile Apps |
|---|---|---|
| Distribution | Often installed from websites, USBs, or disks (uncontrolled sources). | Primarily from app stores with vetting; sideloading possible. |
| Sandboxing | Traditionally weak; many programs have system-wide access. | Strong sandboxing & permissions model by default. |
| Update Practices | Patch management inconsistent; user must install updates manually or via IT. | Automatic updates via app stores (though fragmentation affects Android OS). |
| Malware Risk | High — many decades of malware targeting PCs. | Growing — malware hidden in apps, especially outside official stores. |
| User Behavior | Users more cautious with unknown downloads. | Users often grant permissions quickly, download casual apps. |
| Security Tools | Antivirus, firewalls, IDS/IPS widely deployed. | Limited security tools; OS security built-in but fewer third-party defenses. |
| Unique Threats | Ransomware, rootkits, phishing emails. | SIM swaps, malicious QR codes, sensor misuse, insecure Wi-Fi. |
