Scan Your Computer - Part I


This tutorial explains how to scan your computer and interpret the results.

Why scan your computer?

Trend Micro security software can keep your computer protected in "real-time," so you do not need to start a scan to remove malicious software. However, if your computer performs poorly due to a possible infection, you can still run a scan at any time.

You can choose from three types of scans:

Scan Type


Quick Scan

Scans only the places where threats commonly hide.

Full Scan

Scans the entire computer and external drives, but not network drives.

Custom Scan

Scans everything in the folders that you select.

What happens when your security software detects a threat?

Which scan is best?

All scans check for the same types of threats, like viruses and spyware. Use Quick Scan if you have recently run a Full Scan. Although it takes longer, run a Full Scan if you have time.
