free windows programs you should never miss

 

Everyone who uses a computer ought to think to keep it healthy.But most of them do not know how to do it .So i decided to suggest some really good piece of software which enables them to appear new and continue all the day long.First of all avoid installing junk softwares which are unhealthy for a pc as it simply creates registry entries and when uninstalled leaves behind traces of its files.It may even corrupt the registry and os.Here is a list of softwares you must have.

One of the free softwares which is a must for every windows pc is CCleaner.It is a small software which cleans junk files and registry values and one can control startup programs with it.It helps to speed up the pc during bootup and working.CCleaner is one of the best programs available for windows for free.
For every system it is a must to have an antivirus.If it is an internet security it is very good as it blocks attack from the internet.internet security comes with a firewall too.There are many antiviruses available in the market.Here is our guide to choose antivirus.

It is important to have a software that takes the backup of the files if they are lost.It is one of the most important softwares.consider reading our guide to backup softwares.

A packet sniffer is a software that can block and analyse traffic passing through a network or subnetwork As data stream flow across the network, the sniffer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications.Here we bring you a list of the most popular sniffers used for network analysis.Here are first four tools are mainly meant for Linux Network security , while Cain and Abel is a windows only version.

1.Nmap

works on linux,windows,solaris and bsd.Nmap is a “Network Mapper”, used to discover computers and services on a computer network, thus creating a “map” of the network. Just like many simple port scanners, Nmap is capable of discovering passive services on a network despite the fact that such services aren’t advertising themselves with a service discovery protocol. In addition Nmap may be able to determine various details about the remote computers like operating system,firewall,details about lan card etc.

2.Wireshark

Wireshark is a open source network protocol analyzer for both Unix and Windows.it is also known as Ethereal until a trademark dispute in Summer 2006 You can interactively browse the capture data, delving down into just the level of packet detail you need. Wireshark has several powerful features, including a suprb display filter language and the ability to view the reconstructed stream of a TCP session. It also supports thousands of protocols and media types. A tcpdump-like console version named tethereal is included. problem with wireshark is that it itself has many exploitable security loopholes

3.Tcpdump

Tcpdump was the most popular sniffer before the Wireshark came into market.Eventhough it has no good graphical interface it has less security holes and so more efficient than wireshark It also requires less system resources. While it doesn’t receive new features often, it is actively maintained to fix bugs and portability problems. It is great for tracking down network problems or monitoring activity.

4.Dsiff

it is actually a suite of networking tools like dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy.Excelent for password sniffing and man in middle attack.

5.Cain and Abel

It is a windows only tool for a variety of network testing tasks.It can recover passwords by sniffing the network, crack encrypted passwords using rainbow Dictionary, Brute-Force and Cryptanalysis attacks, recording VoIP conversations, decoding scrambled passwords, decrypting password boxes, uncovering cached passwords and analyzing routing protocols.it has a good GUI interface
