3 Best Free Anti-Malware, Anti-Spyware, Anti-Rootkit Software for PC

by on April 17th, 2010

Having only Anti-virus does not protect you completely against viruses. There are Spywares, Malwares, Worms, Trojans and more….to handle besides just the viruses. Your only chance of being protected is to get the best ‘Internet Security’ software which comes along with ‘Antivirus’ – or – Anti-virus and other Anti-Malware, Anti-Spyware, Anti-Rootkit software. I am encouraging you to have these software because malwares, spywares or trojans can reside in PC silently and send your personal information (critical one) to hackers. One day you will know that your password for FaceBook or email has been changed by any hacker who got your personal information by any anonymous hacking website, even you had up-to-date Anti-virus program installed. Here is my recommendation for top 3 Anti-Malware, Anti-Spyware and Anti-Rootkit software recommendation. Why 3? Because its like tooth paste. You get different benefits in different tooth pastes of different brands. Different security programs have different capabilities to catch different infections and culprits.

Let’s have a look at the threats we are talking about and then proceed to the software to get rid of these.

Spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven’t intentionally installed, if your browser crashes inexplicably, or if your home page has been “hijacked” (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don’t see the symptoms, your computer may be infected, because more and more spyware is emerging.

Trojan is referred to as a Trojan horse which is non-self-replicating malware that appears to perform a desirable function for the user but instead facilitates unauthorized access to the user’s computer system. Trojan horses are designed to allow a hacker remote access to a target computer system. Once a Trojan horse has been installed on a target computer system, it is possible for a hacker to access it remotely and perform various operations.

Operations that could be performed by a hacker on a target computer system include:

  • Use of the machine as part of a botnet (i.e. to perform spamming or to perform Distributed Denial-of-service (DDoS) attacks)
  • Data theft (e.g. passwords, credit card information, etc.)
  • Installation of software (including other malware)
  • Downloading or uploading of files
  • Modification or deletion of files
  • Keystroke logging
  • Viewing the user’s screen
  • Wasting computer storage space
  • Crashing the computer

List and Timeline of Trojan Horses

Rootkit is a software program or coordinated set of programs designed to gain control over a computer system or network of computing systems without being detected. In virtually all cases, the purpose and motive being to perform any manner of malignant acts upon a host computing system. The term rootkit is actually a compound word derived from – and originally referring to – the administrative (superuser) account (or “root” account) in historical operating system terminology – primarily Unix and its various, hybrid incarnations (esp. Linux flavors). The kit suffix refers to either: (a) the individual program mechanism or, (b) a collective of interoperative or interactive mechanisms designed to perform a set of predefined (encoded) tasks. In essence, one part of the kit may initiate the actual entry into the target / host computer system while another part of the rootkit mechanism will act to modify the same process for later, and more simplified means of access. A successfully installed rootkit allows unauthorized users to access the system as root, regardless of the authorized_users_only mechanisms in the operating system, and thus to have full control of the “rootkitted” or “rooted” system on demand. Most rootkits typically hide files, processes, network connections, blocks of memory, or Windows Registry entries from other programs used by system administrators to detect specially privileged accesses to computer system resources. However, a rootkit may masquerade as, or be intertwined with, other files, programs, or libraries with other purposes. While the utilities bundled with a rootkit may be maliciously intended, not every rootkit is malicious. Rootkits may be used for both productive and destructive purposes. Many rootkits hide utility programs. Those that do so usually aim to abuse a compromised system, and often include a so-called “back door” to give the attacker subsequent access at will.

A browser hijacker is a form of malware or spyware that replaces the existing internet browser home page, error page, or search page with its own. These are generally used to force hits to a particular website. Some rogue security software will also hijack the start page generally displaying a message such as “WARNING! Your computer is infected with spyware!” to lead to an anti-spyware vendor’s page. The start page will return to normal settings once you’ve bought their software. Morwill Search and CoolWebSearch are examples of hijackers. PCStats has a good article on ‘Browser Hijacking & How to Stop It‘.

Keyloggers are software programs designed to work on the target computer’s operating system or Remote access software keyloggers are local software keyloggers programmed with an added feature to transmit recorded data from the target computer to a monitor at a remote location.

Keyloggers can:

  • Upload data from your PC to a website, database or an FTP account
  • Periodically email data to a pre-defined email address
  • Wirelessly transmit data by means of an attached hardware system
  • Enable a remote monitor to log into the local machine via the internet or ethernet and access the logs stored on the target machine

Malicious Dialers can be identified by the following characteristics:

  • A download popup opens when opening a website
  • On the website there is only a small hint, if any, about the price
  • The download starts even if the cancel button has been clicked
  • The dialer installs as default connection without any notice
  • The dialer creates unwanted connections by itself and without user interaction
  • The dialer does not show any notice about the price (only few do) before dialing in
  • The high price of the connection is not being shown while connected
  • The dialer cannot be uninstalled, or only with serious effort
