There are different types of Trojan horse infections out there and Backdoor.Joanap.A is (quite obviously) a backdoor Trojan. It means that it exploit system vulnerabilities to allow other malware to enter your computer. Due to its stealthy nature you are recommended to remove Backdoor.Joanap.A automatically and save yourself the trouble of going through its files in important system folders. Don't forget that using a powerful security tool to terminate this backdoor you will also safeguard your system against similar infections.
If you don't do it, however, Backdoor.Joanap.A will continue to provide a remote access to your system without you even knowing it. The problem with Trojans is that unlike rogues they seldom have a graphic user interface, so you cannot know you have been infected unless there are definite infection symptoms, BUT! There are no clear symptoms for this infection as well, so it can cause a lot of damage before you notice anything. For example, it might even be responsible for your computer being a part of a distributed denial of service attack, or it can easily install yet another downloader or a dropper Trojan that leads to an installation to proxy and keylogger Trojans that collect your personal information of financial nature and then send it away over the network.
So, as a result, by being infected with Backdoor.Joanap.A you might actually get robbed in the end. This is the exactly the reason why you have to cut this backdoor off in the first stages of the infection. For that you need to perform regular system scans with a computer security program of choice. You mustn't wait until your system is further compromised by other attackers. Terminate Backdoor.Joanap.A now and make sure that similar malicious programs do not infect your system again.
