Windows remains the primary target for malware authors. A properly configured antivirus suite balances strong detection with low system impact — especially on laptops and gaming PCs.
Configure real-time protection
Enable real-time file guard, cloud threat intelligence, and automatic definition updates. Schedule full scans during idle hours — typically overnight when the device is plugged in.
| Setting | Recommendation | Why |
|---|---|---|
| Real-time scanning | Always on | Blocks malware at execution |
| Cloud lookup | Enabled | Detects zero-day variants faster |
| Full scan schedule | Weekly | Catches dormant payloads |
| Gaming mode | Auto-detect | Reduces scan interruptions |
Firewall and network hardening
Pair antivirus with intelligent firewall rules that block suspicious outbound connections. Review app permissions for unknown programs requesting network access.
