COMPUTER VIRUS

Every day as internet user we open lot of website and download many file like game,application software,songs,movie with this hope we are safe and secure.but my friends this is not true huge number of virus program gets download and install our pc and make us unsecure.Trojen virus is one of them.Lets gather some information about Trojen------
 Viruses work in many different ways. They are harmful to your computer and may even work to steal passwords and personal information. If you have a virus on your computer, make sure you get it taken care of immediately before it ruins your operating system and everything in it.
Trojan viruses steal passwords and other personal information. Trojans can also disable your current anti-virus or anti-spyware software, which makes it easier for other viruses to infect your computer along with the Trojan virus.
A remote access Trojan virus is often hidden in games or other small programs. Through remote access, a hacker will be able to get your personal information off of your computer just by doing a simple search, because they will have total control of your computer through a remote location.
Data sending Trojans work to gain your information through emails, credit card information, or even through your chat contact lists. A key logger can also be installed so that your every keystroke is recorded, which makes it easier for them to determine your credit card number, social security number, or any other number that you type into your computer.
A destructive Trojan is hard to detect, but it will work to destroy the files on your computer. Once this Trojan is installed, it will work to delete all of your information and files, where it will eventually work to delete your operating system. This type of Trojan is very hard to remove, and is often not even detected through normal anti-virus software.
If you suspect you may have a Trojan virus remove at as soon possible and disconnect internet connection.Install highly secured or updated antivirus and scan whole pc.If you found more than 50 file is infected then formate your pc and install new Os but remeber before doing any thing install antivirus first.
Good Luck !!!

Malware, trojans and threats

Most PCs are now connected to the Internet and networks, making easier the spread of malicious software (malware), which includes trojans (also known as trojan horses), viruses, worms, spyware, adware, rootkits and other malicious or unwanted programs.
Like spyware and adware, trojans can get onto your computer in a number of ways, including from a web browser, via e-mail, or in a bundle with other software downloaded from the Internet. You may also inadvertently transfer malware via a USB flash drive or other portable media. It is possible that you could be forced to reformat your USB flash drive or other portable device in order to eliminate the infection and avoid transferring it to other machines. (After all, you don't want to be the one who infected your network at work because you were bringing in some music to listen to.)
Unlike viruses or worms, trojans do not replicate themselves but they can be just as destructive. On the surface, trojans appear benign and harmless, but once the infected code is run, trojans kick in and perform malicious functions to harm the computer system without the user's knowledge.
For example, waterfalls.scr is a waterfall screen saver as originally claimed by the author, but it can be associated with malware and become a trojan to unload hidden programs and allow unauthorized access to the user's PC.
Some typical examples of threats by trojans are as follows:
1.Erase, overwrite or corrupt data on a computer
2.Help to spread other malware such as viruses (by a dropper trojan)
3.Deactivate or interfere with anti-virus and firewall programs
4.Allow remote access to your computer (by a remote access trojan)
5.Upload and download files without your knowledge
6.Gather e-mail addresses and use them for spam
7.Log keystrokes to steal information such as passwords and credit card numbers
8.Copy fake links to false websites, display porno sites, play sounds/videos, display images
9.Slow down, restart or shut down your computer
11.Re-install themselves after being disabled
12.Disable the task manager
13.Disable the control panel
