🛡️ Trend Micro HouseCall — Free Online Virus Scanner & Malware Removal Tool
Trend Micro HouseCall is a free, powerful on-demand virus and malware scanner developed by Trend Micro, one of the world’s leading cybersecurity companies. Designed for users who need a quick and effective second opinion, HouseCall detects and removes viruses, spyware, ransomware, and other malicious software that may have slipped past your primary antivirus program — all without requiring a full software installation.
⚙️ What Is Trend Micro HouseCall?
HouseCall is a cloud-based antivirus and security scanner that runs directly from your computer or browser. It leverages Trend Micro’s Smart Protection Network™, a constantly updated global threat intelligence system, to detect the latest malware, trojans, worms, and suspicious activity in real time.
It’s an ideal tool for scanning PCs that:
-
May be infected despite having antivirus protection
-
Are running slowly or showing unusual behavior
-
Have outdated or disabled antivirus software
-
Need a one-time, fast malware check without installing full security suites
🔍 Comprehensive Threat Detection
HouseCall performs a deep, multi-layered scan of your system to identify threats, including:
-
Viruses and worms that compromise files and programs
-
Trojans, spyware, and rootkits hidden in system files
-
Ransomware variants that encrypt or steal data
-
Potentially unwanted programs (PUPs) such as adware or browser hijackers
-
Web threats and malicious scripts that could harm browsers or email clients
Once detected, HouseCall provides detailed reports and allows you to quarantine or remove infected files safely.
💨 Quick, Lightweight, and Easy to Use
Unlike traditional antivirus software, Trend Micro HouseCall doesn’t require permanent installation. Simply download, run the executable, and start scanning — no registration, setup, or updates needed. Its lightweight design means it won’t slow down your computer during scans.
Users can choose between:
-
Quick Scan: Targets critical areas like memory, system files, and startup processes.
-
Full Scan: Examines all files, drives, and connected storage for deep infection removal.
-
Custom Scan: Lets you specify particular folders or drives to check.
🔒 Cloud-Powered Security
