Q: How to Remove Advanced Mac Cleaner Virus

Remove it as soon as you can.  Do not respond to the site in any way.

https://discussions.apple.com/docs/DOC-2435      Here is some excellent advice from a senior member that gives a link to removing Mackeeper.

You installed a fake "utility" called "Advanced Mac Cleaner." Like any software that purports to automatically "clean up" or "speed up" a Mac, it's a scam. To remove it, take the steps below. Some of the files listed may be absent. Back up all data before proceeding.

If you paid for the software with a credit card, consider reporting the charge to the bank as fraudulent.

Step 1

Triple-click anywhere in the line below on this page to select it:

~/Library/LaunchAgents/com.pcv.hlpramc.plist

Right-click or control-click the highlighted line and select

          Services ▹ Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. Log out or restart the computer.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select

          Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

Step 2

Move the following item to the Trash as in Step 1:

/Library/Application Support/amc

This time you may be prompted for your administrator login password. There's no need to log out after taking this step.

Step 3

Move this item to the Trash:

~/Library/AdvancedMacCleaner

Step 4

Open the Applications folder and move an item named "Advanced Mac Cleaner" (if it's present) to the Trash. Empty the Trash.

This worked great for me:

Thank you so much, this was very helpful!

I got thru step 1 and 2 as you directed, when I got to step three, I got a message that the file couldn't be found.  When trying step 4, the app still won't go into trash.  Started back at step 1 (and 2) and the files have been removed.  Did I mess up step 1 or 2?

I did the same thing as C.R.S. and have the same results. No luck.

I found out how to remove Advance Mac Cleaner here: what is advanced mac cleaner

Go to the folder with your username. Inside you should see the folder 'Library'. If you do not, go up to 'View' and select "Show View Options." Check "Show Library Folder." You should now see Library. Now just follow the instructions in the link above.

What if I cannot get to this location on my infected Mac?  How do I triple click on that line?  Is there another place where I can enter that line's contents on my infected Mac?

Just what I needed. Clicked a broken link to update my "Adobe Flash Player." Huge mistake.

download this file and execute - problem solved

I would strongly advise against the above suggestion by new member niihao89_mvp.   Thoroughly check out the item by asking the community views in our search columns.   It may be an uninstaller but what might it leave in it's wake.  

This post helped me ... thank you.

I just used link from niihao89_mvp before I saw your comment. Now I worry I caused even more damage. Is there anything I could now?   Did I ruin my computer?

Follow my advice earlier on.   You need to remove it.   You may not have ruined your computer, these things can be resolved but they are a nuisance. 

In future check out any download that does not come from Apple or the App Store itself.  I am not saying there are not good apps available elsewhere, but you can always ask here what the community thinks about something you have found.    Await a reasoned reaction and you will be much safer.
