Antivirus Software


Technical Support


Does it have a right-click shell extension to scan files?

A shell extension is a small system utility which gives users the ability to manipulate the settings of the PC through the operating system.

Often, one of the features overlooked by antivirus protection is the usability requirement of quickly double checking a file before using it. Many antivirus programs only automatically search certain file types based on their extensions, so look for a shell extension that forces a scanner window to open and immediately scan any file selected as opposed to one that just launches the scanner interface.


Does it make boot disks and/or have a CD-ROM that can be used for cleaning an infected PC?

Boot disks are required to recover from a nasty boot sector virus, and having the scanner on a CD-ROM means it should be a snap to repair even an infected PC that doesn't have an antivirus program installed.


Product Activation. What is it? And how does it affect me?

Product Activation is a process where a user or application contacts the manufacturer (usually via the Internet, but it can be by phone or fax). It lets the software vendor know some information about the application running and to provide a response that may trigger a change in the application. In the case of antivirus programs this is important as the software activation will signal the beginning of the time cycle for free updates.

It’s perfect for mobile workers. Just take it out — it’s small enough to sit anywhere — turn it on, load a sheet of paper, and start printing.
