Its front-line defenses are only for a small number of programs, but this program effectively launches certain applications on your system in safe mode. Amust 1-Defender quickly shifts Internet Explorer, Microsoft Outlook, Outlook Express and Windows Messenger into safe mode to protect your PC from malware. Its trendy interface runs a scan bar to pass the time as it shifts its protection on. A small green shield was placed alongside IE's logo on the title bar to let us know it was working.

We were glad that, as we surfed, we noticed no slowdowns. Any downloads are subject to a quick scan. No problems were revealed during our testing here either. You'll be able to easily bypass Amust 1-Defender's safe mode shifters by holding down a hot key while clicking a link, opening the page in standard unsecured mode.

While we like its noninvasive approach to protecting our system, this software's coverage is minimal. Free to all, its quick-change protection works great, but most folks will want more comprehensive protection.
