Firstly, hackers place the malware on peer-to-peer (P2P)[2] file-sharing sites where computer users usually come to download software cracks or other illegal files.

Keep in mind that the Trojan horse might disguise as such crack or other innocent software while in reality, it is designed to infect your computer and perform malicious activity. For this reason, we strongly suggest you download programs only from legitimate and official websites, using a direct link if possible.

Another popular malware distribution method is to send malicious spam emails which are holding the infected attachment. Criminals impersonate invoices from well-known companies to trick people into opening the letter together with the added file this way letting the Trojan inside.

Thus, you should pay extreme attention to the emails you receive — open only those from reliable senders and delete others without even opening them. Also, you can keep your computer protected at all times if you employ a professional malware removal software.

How to prevent from getting trojans

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
