how to clean my computer from koobface virus

It's not a virus. It's a Web scam that only affects your browser, and only temporarily. There are several ways to recover.

1. If you're running Safari 8.0.7 or later and you see a dialog with the message “Don’t show more alerts from this webpage,” check the box and click OK.

2. If no other tabs or windows are open, or if you don't mind losing those tabs or windows, force quit Safari. Relaunch it by holding down the shift key and clicking its icon in the Dock.

The following steps may enable you to keep the state of other open tabs and windows.

3. Press the key combination command-W to close the tab or window. A huge box will pop up. Press the return key and both the box and the page will close. If that doesn't happen, continue.

4. Press and hold command-W. You may hear repeating alert sounds. While holding the keys, click the OK button in the popup. A different popup may appear, which you can cancel out of as usual.

5. From the Safari menu bar, select

Safari ▹ Preferences... ▹ Security

and uncheck the box marked Enable JavaScript. If the Preferences menu item is grayed out, go to Step 2.

After closing the malicious page, select from the menu bar

Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data

to get rid of any cookies or other data left by the server. Open your Downloads folder and delete anything you don't recognize.

This just happened to me today. He said that he was from my merchant services company, in regards to my new device (which I just received). And he remoted to my computer and showed me that I was infected with the Koobface virus and that I should purchase a malware software for $199.69 for two years. Is this a scam? Do I really have this virus? I am now freaking out because I am a retailer and I use this computer for some business things as well.

I did not give him any information. I had a weird feeling about it either way, but I just wanted to make sure that because he remotely connected to my computer, he didn't get any information/etc?

Thank you for your help!

That's a question I'm not qualified to answer. But, I suspect someone will come by with an answer for that. If you don't get an answer in a few hours, try starting your own thread. Sometimes older threads don't get as much attention.

Glad that you didn't give them any information.

Best of luck.

If he remotely connected to your computer he could very easily installed spyware or other malware on your computer. He could even have encrypted your computer and held your data for ransom, although you would know if he did that. The only safe thing to do is to erase your drive and reinstall the operating system.

It would be helpful if you indicated the EXACT model MBP that you have and the OSX.

What makes you think that you have koobface virus?

Ciao.

Did somebody tell you that your computer is infected with koobface?

Did you allow anybody enter your computer remotely?

Yes, this was a scam. If you paid for the service, contact your credit card company immediately.
