How to find Trojans in iMac?

[MacLover2011]

How does a person check to see if there are any Trojans on her iMac or iPad? If they find them, how do the get rid of them?
Thank you

Do you have a reason to believe you have a trojan?

it's like saying…"Is there a way to find 1 million dollars in my home?". If you don't have a million dollars…the chances of finding 1 million dollars is petty low.

Finding a trojan on your computer is not easy, but you can check for the following symptoms
- Slow response ( a high percentage of CPU with no programs loaded .... use activity monitor )
- High network usage
This is not a 100% fool proof test mechanism, only an indication.
Usually a trojan will ' call home ' at some point in time to receive orders/commands to execute.
If you are monitoring outgoing traffic using Little Snitch, you can see what applications are contacting the outside world. Then you can verify each application and decide if the outgoing traffic is legitimate or not.

PS.... I don't know about any malware on iOS devices ( your iPad )

Thanks. The running slow problem is the PC Windows 8 laptop I have.
I use the iMac and that was what I was asking about. But now that you mention it, I should look into they the PC is running slow and if there are trojans on it.

Same question again. Ok…you have a Windows laptop that is running slow. But how does this lead us to the question of looking for trojan's on an iMac?

You never mentioned having a problem on the iMac. If you have no problems…then you don't need to look for trojan's. And if there is a problem with the iMac…it should be mentioned in the first post.

And if you're trying to be "proactive"…you should mention this as well.

It's ridiculously easy to avoid any malware that might be aimed at the Mac. Follow these simple steps:

1. Don't pirate software.

2. Don't install or supply your admin password if you're not sure why you're being asked for it.

3. Don't fall for silly trick ware and fake pop-ups.

4. Keep your system up to date,so that Apple can keep updating the built-in Xprotect anti-malware system.

5. Don't click links in emails, copy and paste the URL into a browser and see if it's legit.

That should do it!

And if the problem is on a Windows 8 machine download Malwarebytes and run it. Get the free version here:

https://www.malwarebytes.org/lp/lp4...wPrXuvmLT7wZ_NRZHV3Mj3DsMOc6z5KOHzBoC0hDw_wcB

When you install it make sure you opt out of the "free trial" upgrade. It is a check box you will see when you install it. Update the definitions and scan. It is one of the best standalone scanners that you can run manually.

Yes I heard that's an awesome piece of software. However, I already have Norton and I know it's not good to run two virus applications together. Is it?
