So, how did you possibly got Oremu.a Trojan Virus on your PC in the first place?

Many online users catch Trojan horse viruses without even realizing it. Sadly, these threats have no visible symptoms which can give them away. They also use different forms of disguise and stealth as methods for getting distributed and the chances of catching them without a trusted antivirus software on your PC are oftentimes rather low. The hackers who create viruses such as Oremu.a Virus usually spread them in ways and places where the web users are likely to go and interact with the malware source. Normally, the victims are misled to install the malware, believing that it is actually some useful application, a needed update, an interesting program, an attachment sent from a colleague or some free application, game, torrent, etc. The crooks may often hide their malicious software in some messages, “you won a prize” pop-ups, seemingly harmless files, links, web pages, free installers and offers. That’s why you should be very careful what you click on and what you download. You may randomly come across such infected content on a daily basis and the chance of being misled is actually very big if you aren’t careful and if you don’t have proper antivirus protection.
