Tips for protection against trojans

Trojans are viruses in disguise. They spread so unknowingly and accidentally that one does not get enough time to take any corrective actions like using Trojan Removers immediately. They can hide in anything people search often while on the net. These can include free games, movie, songs, and some others. The attack of a Trojan often takes place while downloading any of these or while carelessly opening an email attachment. The best strategy against Trojans is to be alert against any such dubious looking files, attachments or emails.  
One can take the following precautionary measures to avoid mishaps on their computer system caused by these viruses.
One must ascertain both the source and content of every file before downloading it. You must be sure that you know the sender of the file or are familiar with the file server and also the contents of the file should be trustable. One should especially be very careful if one performs a lot of downloading tasks.
Sometimes even if the sender of the file is a known and dependable person opening a file may be risky. There are many Trojans that automatically try
Even if the file comes from a friend, you still must be sure what the file is before opening it, because many Trojans will automatically try to spread and multiply themselves to friends in an email address book or on an Internet Relay Chat channel. If a friend is sending a file you never wanted or asked for then there is definitely something fishy. Taking precaution at this point saves you from a lot of trouble. So if you are doubtful about a file sent to you just ask the concerned person first or else you can also scan the attachment with the help of a fully updated anti-virus program.
One should also be very tactful against hidden file extensions. Trojans are executable programs, which mean that on opening the file it performs some actions. In Windows, executable programs have file extensions like "exe", "vbs", "com", "bat", etc. One should be very watchful against hidden file extensions. Windows by default conceals the last extension of a file, so that harmless looking "susie.jpg" might actually be "susie.jpg.exe" – a hidden executable Trojan. To avoid getting tricked in this manner it better to cover these troublesome extensions.
One should not use features in programs that automatically take you to preview files. This seemingly convenient feature may prove to be bane for your computer system. Never blindly type commands that others tell you to type, or go to web addresses mentioned by strangers, or run preplanned programs or scripts. This may end up in a Trojan infection or other alarming problem.
It is the general tendency of computer users to have a laid back attitude as they have run anti-virus programs. Unfortunately these antivirus programs do not provide complete protection against many viruses and Trojans even when they fully updated.  Anti-virus programs only serve as a backup and it does not provide all round security to your computer. Specifically designed Trojan Remover is greatly helpful in tackling situations like these.
