It is hard to protect our things from the external threats and in fact it is really hard to protect our computer from attacks i.e. by virus or by any means. We all heard about a particular term which is considered as an enemy for computers and that term is nothing but Trojan horse. A Trojan horse is a destructive program and a tricky one too but a point to be noted here is that Trojan horses never replicates themselves (on the other hand virus replicates).

You cannot determine the annoying ratio of a Trojan as it may vary and can cause numerous things happen on your computer. If your system gets affected by a less annoying Trojan then it may cause some silly effects like, a change in your desktop settings or add icons etc. The more annoying Trojans can cause serious effects like, spreading viruses; it can steal your highly secured information like credit card and bank account details, passwords etc. So here arises a question for all like:” how to prevent a Trojan?” well go ahead to the next paragraph

• Do not download any thing until or unless you are sure that it is 101% safe. Do not click any unofficial/rogue websites or any links that comes in your mailbox or anything which is not safe.
• Install a very good/reliable anti-virus software and update it regularly (updating is highly important). Go for anti-virus software which can scan your e-mail and the files that you have downloaded and also make sure you have a full version of that anti-virus software.
• Install a reliable firewall which can prevent an unauthorized access.

However it is not possible to protect your computer completely but still it is all in your hand to stay updated and give your computer the maximum protection possible.
