A DAT file is a component that is used by a virus scanner as an update to detect viruses that a user may encounter while accessing the Internet and downloading information. Virus scanner companies such as this one use these updates to combat malicious attacks on your PC. Updates should be regularly downloaded and installed as soon as they become available.
Note: Kaspersky Software offers daily, weekly, and cumulative updates for DAT files. To get access to these, visit the related sites link on the right hand site of this review.
