The perfect security enhancement

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
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.
