The perfect security enhancement
a-squared detects reliably:
* Trojans, Backdoors, Keyloggers
Trojans and Backdoors provide strangers with access to your PC. Once a Backdoor is installed, an attacker can take full control of your computer. A Trojan is best described as a piece of software pretending to be something it is not - they often contain Backdoors, and usually arrive as email attachments. A Keylogger is a type of Malware that invisibly records all keyboard activity. a-squared Free specializes in recognizing and eliminating these types of Malware.

* Spyware, Adware, TrackingCookies
Your personal data and information is worth a great deal of money to certain advertising companies. They have no qualms about smuggling software into your system, recording information and spying on everything you do. Adverts that change the start page of your browser also belong in the Spyware/Adware category. a-squared Free completely removes Spyware from your PC. Traces of Spyware in the Registry and Tracking Cookies are also recognized.

* Worms, Bots, Viruses
Worm viruses are currently one of the most irritating phenomena on the Internet. Usually transmitted as dangerous email attachments, worms send copies of themselves to all reachable destinations and cause great damage. Newer network worms/bots use security holes (Exploits) to infect a PC, and can reproduce at an astonishing speed. Without your knowledge, your PC is essentially transformed into a spam-sending zombie! a-squared Free eliminates worms from your PC and prevents them from doing any further damage.

Dialers are small programs that change the Internet access number of a modem-equipped computer to a much more expensive number. Costs can rise as high as several hundred dollars per dial attempt. a-squared Free detects Dialers with special Dialer Heuristics.

Differences to a-squared Anti-Malware:
* Background Guard
To stay protected against new infections of Malware, the a-squared Anti-Malware background guard is required. It includes the double protection using the OnExecution Scan, which scans programs right before they are started with the signature scanner, as well as the Malware-IDS.
This is the most important part of the background guard. It detects Malware using a completely new behavior analysis technology (behavior blocker), which detects and blocks malicious actions of programs immediately. With this technology you are protected from unknown Malware with no signatures available for.
More about the Malware-IDS
The Surf-Protection prevents you from surfing to websites that spread malware. Beside dangerous hosts, you can also block thousands of advertising hosts and servers that spread TrackingCookies.
The scanner and background guard always need the latest Malware signatures installed to be able to provide a perfect protection against the latest dangers. The automatic update of a-squared Anti-Malware installs the updates, which are usually available at least once a day, automatically.
* Scheduled Scan
Let the a-squared Scanner check your PC while you don't need it. E.g. when you are at lunch or at the evening after work. Configure the scheduled scan of a-squared Anti-Malware for your specific needs.
a-squared HiJackFree, the tool for professionals to detect and remove Malware manually, is directly integrated in a-squared Anti-Malware and therefore always achievable. Manage your active processes, all kinds of autorun entries, services as well as all open ports and their attached programs.
