Frequently Asked Questions
Common questions about Quttera ThreatSign – Web Malware Scanner for WordPress
This plugin uses Quttera's unique, patented malware scanning and detection technology. Its multi-layered heuristic engine gathers intelligence from the analyzed system and digests it into weighted rules to detect malicious code. A self-learning mechanism updates the ruleset using Quttera’s worldwide threat intelligence network.
The scanner identifies a wide range of threats, including: Obfuscated JavaScript Injected or malicious PHP code Hidden iframes, redirects, and links Spam and SEO malware Card skimmers targeting WooCommerce checkout pages Suspicious external links Backdoors and PHP shells Infected or modified WordPress core files Heuristic and AI-powered analysis enables detection of new or unknown malware, not just known signatures.
The free version includes: Malware Detection: * On-demand scans from the WordPress admin * Blacklist checks across 40+ services * Malware detection (JS, PHP, backdoors, spam, iframes, skimmers, etc.) * Investigation report with severity levels (Clean, Potentially Suspicious, Suspicious, Malicious) Brute Force Protection: * IP-based locking and failure detection * User account lockout protection * IP whitelist and blacklist management * Email alerts for locked accounts Bot Protection: * Rate limiting and risk-based evaluation * Legitimate bot recognition * REST API and WooCommerce endpoint protection * Configurable protection modes Admin User Monitoring: * Real-time detection of admin user changes * Email alerts for additions, removals, and role changes * Database audit trail with snapshots To enhance protection with automated responses, scheduled scanning, and advanced WAF features, upgrade to ThreatSign Website Security.
Traditional scanning uses signature matching. Heuristic scanning uses rules, weight-based systems, emulators, flow analyzers, and statistical methods to detect potentially malicious functionality, even in previously unknown threats.
Quttera’s severity levels indicate potential risk. If you're unsure whether a detection is harmful, our team can help. Contact us via ticket at https://helpdesk.quttera.com, email support@quttera.com, or the plugin’s WordPress Support Forum.

This usually happens if your hosting assigns only one PHP worker. The scan process occupies the only worker, temporarily blocking the site until the scan completes.
Ensure JavaScript is enabled and your firewall isn’t blocking plugin requests. The plugin communicates with the backend via JavaScript-generated HTTP requests.
Use the "Download Report" button, save the file, and send it to us via https://helpdesk.quttera.com/open.php.
Your hosting may not allow WordPress Cron to function properly. You can enable an alternative cron method by adding this line to wp-config.php: define('ALTERNATE_WP_CRON', true);
