PC Tools' Alternate Operating System Scanner Review

Use AOSS to scan for viruses before Windows starts

PC Tools Anti-Virus Scanner

PC Tools' Alternate Operating System Suite (AOSS) is a software suite for Windows that functions not only as a free bootable antivirus program but also a file recovery and data destruction program.

The menus are easy to navigate through and you can start a virus scan in just a few moments after booting into AOSS.

What We Like

  • Has a graphical user interface.

  • Easy to work with.

  • No custom settings (scans are easy to start).

  • Includes other useful free tools.

What We Don't Like

  • Built for the Windows OS only.

  • No custom settings (not very advanced).

  • Over 350 MB download size.

PC Tools is no longer available. As such, you can not browse for the AOSS download on their website and no more updates will be released.

This review is of the final version of the program, version 2.0.5, which was released on December 9, 2010. 

Installing Alternate Operating System Scanner

This bootable AV program is available as an ISO file called AOSS.iso. After downloading it from the link above, you have to burn the Alternate Operating System Scanner program to a disc. Then, you can boot to it before Windows starts up.

Thoughts on Alternate Operating System Scanner

Because Alternate Operating System Scanner doesn't have any scan options or other custom settings, you can begin a scan fairly quickly once you've booted to the disc. On that note, if you're looking for a program that lets you perform particular scans like checking certain folders only, you won't find it with AOSS.

I still like Alternate Operating System Scanner even though it doesn't have custom options because the program is really easy to use. Unlike some other bootable antivirus programs, AOSS lets you use your mouse to control the menus, which makes it very simple to use.

Just choose Anti-Virus scanner from the AOSS main menu and then select the partitions you want checked to immediately begin a scan.

Also from the main menu are some additional tools, such as a system shell and file manager that lets you compress, remove, and copy data.
