Anthena is a typical backdoor trojan, which simply means that hackers can gain access to your PC and literally take control of it. This malicious application allows the hacker to steal your private information, and modify your system settings and files. All of this can lead to damage to your computer, selling of your private information and other dangerous scenarios.
Anthena and other parasites of this nature may place additional malware on your PC, which causes more problems. Your operating system may become unstable, and the performance of your computer will likely be affected.
To remove Anthena manually, you must kill all associated running processes. You must then detect and delete all related files and values in the Windows registry, which is a difficult and potentially harmful process. To remove Anthena automatically, it is advised that you use a reputable antispyware tool such as Spyzooka, which will detect and remove all traces of parasites quickly and efficiently.
