Trend Micro PC-cillin Internet Security

What is Trend Micro PC-cillin Internet Security?

Trend Micro Internet Security is an antivirus/Internet security program which includes antivirus software, web threat protection, browser cookie removal, parental controls and a computer firewall. Trend Micro's Smart Protection Network deploys bots to verify websites visited by users of Trend Micro Internet Security. While users of the software are visiting a website, the Trend Micro bots break security measures and rules specified by the website administrator and display malware characteristics. The antivirus software uses the trust websites have for users with administrative and other privileges to circumvent website security measures to allow Trend Micro's bots the opportunity to download privileged information or to inject files to the website.


During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The primary executable is named pccmain.exe. The setup package generally installs about 42 files and is usually about 322.93 MB (338,617,207 bytes).
