01.Is Windows Defender enough for Gamers?
In 2026, software like Norton, McAfee, and Avast have become extremely heavy "bloatware". Windows Defender is already one of the best antiviruses in the world, but its default behavior is aggressive towards game files (.exe, .dll), which causes **micro-stuttering.**
If you simply disable your antivirus entirely, your PC remains vulnerable. The best approach is **Selective Optimization:** maintaining protection, but preventing the scanner from reading your games while you are playing.
Don't do it Manually.

02.How to manually create exclusions
To prevent Defender from scanning files in real-time in the middle of a match:
Go to Settings > Virus & threat protection > Virus & threat protection settings > Manage settings > Add or remove exclusions.
Add your game's directory (Ex: SteamLibrary, Riot Games).
03.The Voltris Shield Revolution (Security Hardened)
In **Voltris Optimizer**, we developed the **Voltris Shield**. It is not a new antivirus, but an orchestration layer over Windows Defender that guarantees maximum performance and ironclad security.
- **Scan Throttling:** Lowers the CPU priority of the
MsMpEng.exeprocess during detected games. - **Auto-Trust Logic:** Automatically identifies major market releases and securely adds exclusions.
- **Malware Guard:** Intelligently protects against ransomware in critical documents and photos folders.
Don't do it Manually.
