This is a dangerous software. A trojan horse is capable of recording keystrokes and gaining access to your computer.


How to Protect Yourself against Malicious Software

The most basic way of protection from malicious software is password security. Passwords are generally the first form of protection against these forms of software. You should never give out any passwords to anyone in order to protect your personal information and your computer. A good password includes at least one number, contains six characters, includes different symbols and also incorporates both upper and lower case letters.

It is also imperative that Firewall is installed on your computer in order to protect against bots. It is important to not download any unknown software provided to you in untrustworthy sources such as chat rooms or invalid e-mails.
