Remove Malware Using These 8 Free Tools!

Malware is a menace, and it’s gaining prominence with each day.

Tuesday, May 13, 2014: Hackers today are not only becoming increasingly successful in finding new ways to break into computers, but achieving a one hundred per cent success rate at the same time. Cybersecurity firms are witnessing a rampant multiplication of cyberattacks categories that now range from malware and spyware to highly sophisticated breaches directed towards large businesses/enterprises. Today we bring you a list of 8 free tools to get rid of malware.

1.Ad-Aware

Anti-spyware and anti-virus program developed by Lavasoft that detects and removes malware, spyware and adware on a user’s computer.

2.Emsisoft Emergency Kit

The Emsisoft Emergency Kit contains a collection of programs that can be used without software installation to scan for malware and clean infected computers.

3.Norman Malware Cleaner

This simple and user friendly tool not only detects malicious software but also removes them from your computer. By downloading and running the program it will clean an infected system completely.

4.SUPERAntiSpyware

Shareware which can detect and remove spyware, adware, trojan horses, rogue security software, computer worms, rootkits, parasites and other potentially harmful software applications. Although it can detect malware, SUPERAntiSpyware is not designed to replace antivirus software.

5.Spybot

Spybot Search & Destroy is a set of tools for finding and removing malicious software. The immunisation feature preemptively protects the browser against threats. System scans and file scans detect spyware and other malicious software and eradicates it.

6.Combofix

Executable software, intended for users with advanced computer skills to run it only on occasions where a regular antivirus would not detect certain malware, or where an antivirus cannot update or otherwise function.

7.Microsoft Security Scanner

Free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.

8.Malwarebytes Anti-Malware

Made by Malwarebytes Corporation, it was first released in January 2008 and is available in a free version, which scans for and removes malware when started manually.

Welcome to TCP/IP Part 7

IP ADDRESSING

An IP Address is a numeric identifier assigned to each machine, or host, on an IP network.  It also happens that each IP Address is software and not a hardware address; the hardware based addresses, which are hard coded on the network interface card (NIC) and is the media access control address (or MAC Address) and is a Data Link Layer hardware address that every port or device needs in order to connect to a LAN segment.  Our primary purpose of this section is the IP Address.  IP Addresses were designed to allow hosts on one network to communicate with a host on another network.

IP Terminology

It is rather rudimentary, but you know the drill as repetition of the basics is the mother of skill. 

Bit is one digit, either a one (1) or zero (0).

Byte is 7 or 8 bits, dependent upon use of parity; always assume an 8 bit byte.

Octet is made up of 8 bits, is an ordinary 8 bit number and is interchangeable with byte for the purposes of this information.

Network address is the designation used in network routing to send packets to another network – for example 10.1.1.0, 172.16.20.200, and 192.168.1.100.

Broadcast address is the address used by applications and hosts to send information to all nodes and devices on the network – for example 10.255.255.255, 172.16.255.255, or 192.168.1.255.

IP ADDRESSING SCHEME

IP Addressing consists of 32 bits of information, which are segmented into 4 separate sections referred to as octets or bytes.  The address can be depicted in one of the following ways:

  • Dotted decimal, or 10.8.30.56
  • Binary, or 00001010.00000100.00011110.00111000
  • Hexadecimal, or 0A.08.1C.38

The 32-bit address is a structured, or hierarchical, address and is used for a specific purpose that permits larger numerical values, its maximum allotment being 4.3 billion.  Here is a handy little tool as you will be expected to determine the powers of two, check out the POWERS OF 2 TABLE – this will aid you as you learn, or relearn the multiples of two.  Also, it will be a help to some degree as you start learning the newer format IPv6; the reason being IPv4 has run out of blocks of numbers during of 2011, but we will get into IPv6 at a later time.

Network Addressing

The network address, also referred to as the network number, uniquely identifies each network.  Every device, node, host, or machine shares part of the IP Address assigned to it. (i.e., 192.168.1.100 is the IP Address assigned by DHCP; however, as it is /24 and a Class C IP Address its network address would be 192.168.1.0. A Class B, a /16 mask, address would go like this 172.31.1.100 as the IP Address and the network address would be 172.31.0.0.  And Class A address would be, since it has a /8 mask, 10.35.172.242 as the IP Address with a network address of 10.0.0.0.)

Private Address Space

 
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:
 
     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)
