The original PC-Cillin was an antivirus application. In 2006 it's grown into a full Internet security suite with firewall, spam filter and parental controls.

Computer security is essential to prevent PC performance loss and identity theft. Spyware clogs system resources, taking up disk space and slowing down the PC. Some may also be capable of stealing personal information. Fake sites to gather information are also plentiful and many emails try to fool the reader into visiting one of these sites to enter credit card numbers or logins to other legitimate sites.

For any questionable files which arise and are not confirmed by PC-Cillin as an Internet parasite, they can be submitted to Trend Micro's EDoctor Lab for analysis and a response can be expected within 48 hours. This system ensures if there is a malicious file which has not gotten into the database yet, it surely will do soon once it has been discovered on the loose. Public input into research is invaluable in keeping security applications up to date.
