Emsi Software just released a mind blowing offer of 100% discount for a one-year license for one PC on its flagship product, a-squared Anti-Malware (regularly priced at $39.95). The promotion was twittered at 11:11 CET and will last until tomorrow, at the same time. That gives you a 24-hour window to get the product for free.

For all other orders on the Emsi Software web page, the same 24-hour $40 price drop is applied. Thus, the most expensive package, which includes a one-year license for five computers, originally priced at $120, dropped at 80 bucks for this short period of time.

You can see the price bash on its 24-hour discount order page and check out the discounts for all orders. However, there are some limitations as to who can benefit from this promotion. The catch is that the discount is valid only in combination with a new user account (which can be created freely as soon as you hit the Buy Now button). So, existing customers cannot take advantage of this free ticket for improved PC protection.

The key features of a-squared Anti-Malware include multi-engine scanning, safeguarding against all sorts of threats (viruses, spyware, rootkits, etc.), behavioral analysis of all active programs, community and cloud-based help to take your decisions when in doubt. As far as performance goes, the application does one helluva job and is equally easy to handle for both advanced users, as well as average-skilled ones.

Over time, the product has attracted plenty of users, their number currently passing 5 million, according to the Emsi Software website. That makes a pretty large and quite reliable community that can accurately point you to the right decision when in doubt upon installing a new program.

With a-squared Anti-Malware, you will also benefit from the a-squared HiJackFree system analysis tool that can help advanced users track the source of malware running on the system. It sports a process manager that shows complete details of the running items (loaded modules, process details and properties sheet), per process port usage, startup items and full set of services.
