| Component | Technology |
|---|---|
| Extension Framework | Chrome Extension Manifest V3 |
| Frontend | HTML5, CSS3, Vanilla JavaScript |
| API Integration | VirusTotal API v3, Mail.tm API |
| Remote Isolation | Browserless.io, Custom RBI APIs |

The Smart Prevention System operates as a content script that runs on every webpage you visit. It performs three layers of protection:
- Identifies and removes ad elements using CSS selectors
- Blocks common ad network requests
- Improves page performance and privacy
- Analyzes URLs and page content for suspicious patterns
- Matches against known malicious domain database
- Blocks access before page loads completely
// Automatic URL scanning workflow
1. User navigates to new URL
2. System checks cache for previous scans
3. If not cached, submits URL to VirusTotal
4. Polls for analysis results (max 30 seconds)
5. Displays warning if threats detected
6. Blocks downloads from malicious sourcesYou can customize Smart Prevention behavior:
// Toggle individual components
- Ad Blocking: ON/OFF
- Malicious Detection: ON/OFF
- VirusTotal Scanning: ON/OFFExample warning for suspicious content
When threats are detected, NULL VOID displays informative warnings:
- Pending Analysis: Yellow warning while VirusTotal analyzes the URL
- Suspicious Content: Orange warning for potential threats
- Malicious Detected: Red warning with detailed threat information
- Safe Content: Green indicator for verified safe URLs
- JavaScript ES6+: Modern JavaScript features and async/await
