OK, so I've had MacKeeper for a long time because my system was a little slow.  Little did I realize that even though it said it was doing a security scan, I had never installed the Antivirus part and so I guess we were just pretending.  Yesterday, when I was about to go get a new hard drive, I found this out and installed and ran the antivirus ware.  Lo and behold: four viruses and a trojan.  (Now I realize I didn't get their names, and can't find any history since deleting them.  Doh!)

 

After I removed them, my MacBook gradually began to run like the dream it was made to be.  Then, I watched 2 hrs of Radiohead on Youtube and now - not quite so dreamy.  It's just doing random, weird things - or rather, not doing them.

 

What do I do to restore my system now?  Is it back to the Windows days of wiping the drive clean and starting over?  Waddyall think?  Should I continue to use it and let it self-heal, as it was before?  Continue to run MacKeeper cleanups?  Get a new hard drive?

 

I must admit I'm fuzzy now on viruses, trojans, malware, etc.  The Flashback trojan is probably what I had, since over the months I kept declining an "Adobe Flashplayer update."  I know this one starts showing up as problems with Safari, which is what I experienced.  Yet even just now, trying to type into the search bar in Firefox, suddenly the computer was giving me that "no way" noise, as though we don't type characters there.  One of the first symptoms of something really wrong - other than general slowness - was the disappearance of icons from the dock.  Typical stuff. 

 

But it was getting pretty bad, so I just don't know what to expect as far as any potential system damage, or what to do about it.  Thanks.

    Make sure you have cleared out ALL part of MacKeeper:

     

    Further opinion on it and how to uninstall MacKeeper malware can be read here:

    Do NOT download or use the ‘MacKeeper uninstaller’ from the Zeobit site, as this will cause even more damage to your operating system.

     

    This is also worth reading:

    As regards the Flashback Trojan, if you have installed ALL updates to Snow Leopard, and turned off Java (but not Javascript) on your Mac, you should be clear.

    If you want to use MacKeeper and risk damaging your system, that of course is your call.

    Chances are the update suggestions are coming from the new feature provided by the new FlashPlayer preference panel. The Flashback Trojan has not used that method of installation since last year and there have been several updates recently, including yesterday.  You really do need to keep it up-to-date so if you can't trust the notifications, just go to the Adobe site and download it.

    It's certainly possible that you did some permanent damage to these applications by using MacKeeper to strip "unneeded code" from them.  These cleaner apps have a longstanding reputation for doing this. I would recommend you replace any application that your having problems with from source.

    I can see you and others are very concerned about MacKeeper.  I do not believe it has caused me any problems, and contrary to being all 'front end' good looks, I found it very useful yesterday once I dug into it.  For example, it helped me recover almost 20GB of wasted memory that I never would have systematically found on my own - in addition to removing the Trojan and viruses.

    MacKeeper is a real "hot-button" topic around these forums. Some people claim it is actually worse than any malware.

     

    I don't think MacKeeper is any worse than any other anti-virus or "clean-up" software. That being said, I also don't think any of them are necessary. I am concerned about this "wasted memory" too. Certainly, none of the trojans or viruses it found were any risk to you. Like all Mac antivirus software, it searches almost 100% for Windows malware, because almost 100% of malware is for Windows. The only thing you need to run software update on a regular basis. If you did have one of the very rare Mac trojans, software update will remove it.

     

    Considering you are shopping for a new hard drive, I suggest taking this opportunity to get a fresh start. Install a fresh copy of Snow Leopard and update to Lion if your computer and software support it. Keep any and all antivirus or "cleanup" software off of it.

    I wonder where RHarperMc thinks that 20 GB of "wasted memory" came from.

    ... For example, it helped me recover almost 20GB of wasted memory that I never would have systematically found on my own -

     

    I have a file cabinet in my office. There are a lot of important documents in there. Contracts, IRS data, that sort of thing. But there is probably a lot of unnecessary stuff in there too.

     

    But hey, a couple of guys in a truck knocked on the door and offered to clean it out... for free!
