Virex: Why Update?

To offer you the best protection possible, the virus definition (DAT) files that this software uses to detect viruses are updated regularly. Although your software uses heuristic analysis that enables it to detect some previously unknown strains of viruses or malicious code, many new virus types and other agents appear frequently.

Often, your existing software cannot detect these intruders because the DAT files that came with it are outdated. For maximum protection, we strongly recommend that you update your files on a regular basis. There are two methods available to you:

Weekly updating by manually copying the DAT files in to the vscanx folder

Monthly updating by using the Virex 7 update package installer

We recommend that only advanced users choose the weekly method.

The date that you installed the most recent DAT update appears in the Results area of the Virex window.
