Trojan Programme Detected?

Hello, Macbook users!

I use Macbook Pro and I recently received a warning from Kaspersky that my mac is infected with Trojan virus.

My school re-imaged my MacBook on Thursday 22 August 2013 and Kaspersky detected "Trojan.Win32.Hosts2.Gen" in File / Private / etc / hosts on Friday 23 August 2013. (It's so weired! I NEVER torrent!)

However, I saw a post on Kaspersky discussion forum and some of the users aruge that they might have received false warning. So, I'm just wondering if this was just a false warning or real one. But I guess my Mac is really infected with Trojan virus since I am running few anti virus programmes at the same time and all of them give me warnings about virus / infected files. I disinfected the detected files but I'm still concerend.

I did some research about Trojan virus and I am so worried now. 😟

So what I know is:

1. Trojan programme is a very dangerous virus programme.

2. Hackers can hack through my computer if my computer is infected with Trojan virus.

3. Recent Trojan programmes are so smart they hide themselves and even Terminal cannot detect them.

I'm so concerned right now I can't do anything 😟

So my questions are:

1. How do I completely get rid of Trojan virus? I'm scanning my Mac with Kaspersky, Magician, Sophos and Dr. Web Light now and they give me different results so I am kind of skeptical about using Anti-virus programme.

2. Is there any possibility that I got Trojan because of re-imaging? Would it be better if I ask the school to re-image my computer again?

3. Can re-imaging get rid of Trojan virus?

4. If the answer to question 2 is no, how did I get Trojan virus?

5. What do the Trojan remains do? Is there any possibility that remains do any harm to my computer?

6. How do I view hidden Trojan files?

7. Could it be a false warning?

I'm so confused and frustrated right now. I never had virus before and I thought Mac don't get virus. I'm really concerned that I might lose all my files and documents.😟 I asked around a bit but I still don't know what to do. Please, please, please help me!


Thanks in advance! 🙂
