Virus patterns

Trend Micro provides users the capability to detect and clean systems infected by known malware.

When a malware is reported, TrendLabs (Trend Micro's global network of antivirus research and product support centers) immediately update the pattern, and releases an OPR or CPR. The virus scan pattern and virus scan engine work hand in hand to enable Trend Micro products to detect latest known malware. To know the lowest pattern version that could detect all samples of a specific malware, check out the pattern file needed specified on the Virus Encyclopedia page.

For malware that are likely to spread, the Virus cleanup template is also updated to enable infected systems to be automatically cleaned by Trend Micro products.
