The W32/Tearec.A.worm (also frequently classified as a Win32 file infector or autorun worm) is a highly aggressive malicious program that primarily targets Windows operating systems. It spreads by copying itself into legitimate executable (.exe) files, attaching itself to network shares, and infecting removable storage devices like USB flash drives. Once executed, it can significantly degrade system performance, block access to security websites, and bypass local antivirus definitions.
Because it is a file infector, standard antivirus deletions often fail because the worm actively injects its code directly into core system processes and software executables. Step-by-Step Emergency Removal Guide
To completely remove the worm and prevent it from continually duplicating itself, you must isolate the system and run a targeted cleanup. 1. Isolate the Infected Computer
Disconnect immediately from the internet (unplug Ethernet and turn off Wi-Fi) to stop the worm from communicating with command servers or spreading to other devices on your local network.
Remove all USB drives, external hard drives, or SD cards, as the worm heavily targets these via autorun features to spread. 2. Boot into Safe Mode with Networking
Worms often load dynamic-link libraries (DLLs) at normal startup to protect themselves from deletion. Booting into Safe Mode prevents these processes from launching.
Hold down the Shift key while clicking Restart in your Windows Start Menu.
Navigate to Troubleshoot > Advanced Options > Startup Settings and click Restart.
Upon reboot, press 5 or F5 to select Safe Mode with Networking. 3. Run Targeted Malware Scanners
