Emisoft Emergency Kit

It's the program Emisoft which in a sense replaced the valuable A-Squared free, become subject to charges. Even the interface is virtually identical to that of A-Squared Free.

Emisoft Emergency Kit is portable application (requires no installation) that allows you to find and remove malware and spyware from your computer. It can run a quick scan or a smart scan, where the program will check only the critical areas of the operating system, or even a full scan, where each file is analyzed.
The download is small (100 MB), but the ability to scan and removal are among the best ever (just like A-Squared Free).
