The trojan virus can steal sensitive data , delete files and modify documents 

These are some of the most common:

• Backdoor Trojan - These Trojans can create a “backdoor” on a users’ computer, allowing the attacker access to the machine in order to control it, upload stolen data and even download more malware onto the computer.
• Downloader Trojan - The main purpose of these Trojans are to download additional content onto the infected computer, such as additional pieces of malware.
• Infostealer Trojan - This Trojan’s main objective is to steal data from the infected computer.
• Remote Access Trojan - This Trojan is designed to give the attacker full control over the computer.
• Distributed Denial of Service (DDoS) Attack Trojan - This Trojan performs DDoS attacks, which are designed to take down a network by flooding it with traffic.

How to Stay Protected:

• Computer security must begin with an Internet security suite. Run periodic diagnostic scans with your software. You can set it up so the program runs scans automatically during regular intervals.
• Update your operating system’s software as soon as the updates are available from the software company. These groups tend to exploit security holes in outdated software programs. In addition to operating system updates, you should also check for updates on other software that you use on your computer as well.
• Don’t visit unsafe websites. Most Internet security suites include a component alerting you that the site you’re about to visit is unsafe.
• Don’t download attachments or click on links in unfamiliar emails.
• Protect accounts with complex, unique passwords.
• Finally, you should always keep your personal information safe with firewalls.
