It's not really malware but it is extremely poorly written software. It has a fairly good user interface and is easy to use but, when the virus protection kicks in, it hogs all of the CPU resources and everything else slows to a crawl. Consider thirty seconds merely to open a large folder. I had it for several weeks and trashed it. Also, trashing it is easy. The old "drag to trash can" works just fine.

CLEAN YOUR MAC VIRUS

I am REALLY p...d ! Seven months after i installed "clean your mac" this virus/malware (wich i bought from APPLE!!) my computer is STILL infected with this virus! After installing this MACKEEPER/ZEOBIT .... firm, it my mac went so slow that i couldnt work with it anymore.
I got in touch with this east european based virus sellers helpdesk. I wanted to get rid of this virus program. The help i got consisted out of them trying to selling me more software.
After that i visited all the forums from Apple. Found i am one of the thousands victems they made. Tried some of the solutions i found here.
So i decided to reformat my hard disks and install all my programs again.
But STILL, whereever i go i get pop-up for this malware program. Some SO bad that the only choice you have is eigther click on oke to install this rubish again OR you have to close safari to get rid of this virus attach!!
I have been writing to Apple, who peddle this virus without any answer!! Safari, same thing
And now i am fat up !!
If Apple is in need of a couple of million more, no problem, they deserve it. But if, after EVERYTHING i have been reading here, still sell this malware/virus and dont CARE about their customers enough to so something about it, then it stops for me!!
I am shure that the Apple delete police will take this edit away again, and i will get another B....T email that "according to our rules......." but then we will take this a couple of steps further! We are now, just started, 1290 victims of this zeobit, and we are building a website about their policy how to push this virus thrue everybodys troath, and the lack of reaction to this from Apple.
And we will make SHURE that whenever someone in this world types in zeobit, mackeeper, clean your mac, we WILL be the number one hit in Google!!
Because now they REALLY p...d us off !!
PS...just to show how Apple thinks about their precious zeobit, i found out that any comnination of the words zeobit-mackeeper with words we use everyday, or in connection with organised crime is enough to refuse your edit.

Consider that people here have been helping and telling people and some wrote up their own User Tips and that Apple has a tech note, a link at the top of this and other forums, on how to avoid, not installl, and remove this type of ransomware malware.

Any mac user use some kind of apps to "clean" your mac???

i know that a lot of software are build for "CLEAN YOUR MAC", software like clean my mac, mac keeper, ccleaner. etc
they all said that when we use our mac, there are a lot of "dummiy files " like language pack or used history .ect that need to be cleaned.
if we dun clean it, it will make the system laggy.
i know some ppl on the internet said its true,then other ppl said that all these softwares are jus malware, its totally unecessary to use all these.
the mac ox system will clean itself.
which one is true???
did Apple claim or announce anything about these software???
If its true,the softwares can clean your mac, how come all of these apps CANT go to Mac App Store???
IF its true, you guys use what software to run the cleaning process???

Macs do not need "cleaning". Apps such as the ones you mention have the ability to wreck your Mac.
If its true,the softwares can clean your mac, how come all of these apps CANT go to Mac App Store???
Because they are not safe to use.
There are apps in the App Store that suggest the ability or necessity to "clean" memory or unwanted files. They are worthless and are only capable of degrading performance and wasting power. They will also waste your time and your money. Deleting localization files will cause problems and cannot be un-done without reinstalling OS X. Language files use a negligible amount of disk space.
IF its true, you guys use what software to run the cleaning process???
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Suggestions for Mac maintenance
Make redundant backups, keeping at least one off-site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine.
Keep your software up to date. Software Update can be set to notify you automatically of updates to the Mac OS. Some third-party applications have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.
Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” “extenders,” “cleaners,” “defragmenters,” “firewalls,” “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” or "utilities." With very few exceptions, this kind of material is useless, or worse than useless. The more actively promoted the product, the more likely it is to be garbage. The only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Never install any third-party software unless you know how to uninstall it.
The free anti-malware application ClamXav is not crap, and although it’s not routinely needed, it may be useful in some environments, such as a mixed Mac-Windows enterprise network.
Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until recently, but are now increasingly common, and increasingly dangerous. There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable. Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a known corporate brand, such as Adobe Flash, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” “rebuilding the directory,” “running periodic scripts,” “deleting log files,” “scanning for viruses,” or “repairing permissions.” Such measures are for solving problems as they arise, not for maintenance. The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Don’t waste money on Disk Warrior or anything like it.

Box appeared "clean your mac" then lost admin rights in some files, box appeared "clean your mac" then lost admin rights in some files

box appeared "clean your mac" then lost admin rights in some files. How can i restore those rights?

This sounds like you may possibly have been infected with MACDefender.
Malicious software dubbed "MACDefender" (also goes under the name of MacProtector, MacGaurd, MacSecurity or MacShield) takes aim at users of the Mac OS X operating system by automatically downloading a file through JavaScript. But users must also agree to install the software, leaving the potential threat limited.
The new MACDefender malware was first noted on April 30, 2011 by users of the Apple Support Communities, and was highlighted on May 2 by antivirus company Intego. If the right settings are enabled in Apple's Safari browser, MACDefender can be downloaded to a system after a user clicks a link while searching the Internet.
"When a user clicks a link after performing a search on a search engine such as Google, this takes them to a web site whose page contains JavaScript that automatically downloads a file," Intego said. "In this case, the file downloaded is a compressed ZIP archive, which, if a specific option in a web browser is checked (Open 'safe' files after downloading in Safari, for example), will open."
More details here:
http://www.reedcorner.net/news.php/?p=138#more-138
However, users must still agree to install the malware after it downloads. After the ZIP file is extracted, users are presented with the "MACDefender Setup Installer," at which point they must agree to continue and provide an administrator password.
Because of the fact that users must agree to install the software and provide a password, Intego categorized the threat with MACDefender as "low."
Users on Apple's support forums advise killing active processes from the application using the Mac OS X Activity Monitor. MACDefender can then be deleted from the Applications folder by dragging it into the trash. There is also a 'MacDefenderKiller' uninstaller available here:
http://www.macupdate.com/app/mac/38520/macdefenderkiller
On May 24 Apple issued this Knowledge Base Article on how to avoid or remove the MacDefender malware (which has been updated several times):
http://support.apple.com/kb/HT4650
But that does not mean it is over. On May 25, MacGuard is launched:

Further information here:
http://www.macworld.co.uk/news/index.cfm?olo=email&NewsID=3282245
Apple released Security Update 2011-003 on May 31, 2011, which adds malware detection and removal for the "MAC Defender" scam and delivers a daily update mechanism for updating subsequent malware definitions. This is for Snow Leopard only.
The security update for Mac OS X 10.6.7 is available from Software Update or the company's Downloads page. Installing the update does not require a system reboot.
http://support.apple.com/kb/DL1387
(The malware is not to be confused with MacDefender, the maker of geocaching software including GCStatistic and DTmatrix. The company noted on its site it is not affiliated with the malware.)
Trojans and other malware spreads through search engines like Google via a method known as "SEO poisoning." The sites are designed to game search engine algorithms and show up when users search for certain topics.

Clean your mac utilities

i have a MBP early '11 15 inches. is it worth getting one of the "clean your mac" utilities?
im feeling that after a prolonged session of usage it gets a bit slower.

There are usually only a few software things that slow a Mac down, corrupted caches and/or a nearly full hard drive, and/or running some sort of taxing background software (anti-virus) or runaway process.
The only cleaning utility I recommend is the free OnyX, as it can delete all the caches and rebuild them, thus eliminating the source of the corruption.
Why is my computer slow?
Sure over a lot of time OS X upgrades and lots of software installs/uninstalls with a nearly full hard drive can cause slowdowns as the less effective sectors are being used, then a defrag is certainly a option, provided there are no other software related issues.
How to safely defrag a Mac's hard drive
What can't be helped is more recent OS X verisons on older hardware, more RAM can assist if your not running with enough.
Also yours is a Early 2011, if you bought the bargin basement model, that could be the reason why 10.8 is slow.
Also there has been complaints that 10.8 is just generally slow to begin with, why I stuck with 10.6 and a very fast machine instead.

Clean your mac??

I actually have a question. I get these "clean your mac" pop ups every now and again and I was wondering if they were legit or if it is some sort of virus?
Thanks!!

Ignore them. What they are selling you don't need to spend your money on. All you really need to know you will find here:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc. Other utilities are also available such as Onyx, Lion Cache Cleaner, CockTail, for example.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that the Snow Leopard version will also work with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Backuplist
Carbon Copy Cloner
Data Backup
Deja Vu
iBackup
JaBack
Silver Keeper
MimMac
Retrospect
Super Flexible File Synchronizer
SuperDuper!
Synchronize Pro! X
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup

For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utility is: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion, Apple has included built-in malware protection that is automatically updated as necessary. To assure proper protection, update your system software when Apple releases new OS X updates for your computer.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, Mountain Lion Cache Cleaner 7.0.9, Maintenance 1.6.8, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
If you are using Snow Leopard or earlier, then for emergency cleaning install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
Repair the hard drive and permissions beforehand.
Update your backups in case an update goes bad.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. You can never have too many backups. Don't rely on just one. Make several using different backup utilities. My personal recommendations are (order is not significant):
     1. Carbon Copy Cloner
     2. Get Backup
     3. Deja Vu
     4. SuperDuper!
     5. Synk Pro
     6. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
Final Suggestions
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

Most if not all maintenance is for troubleshooting problems. If your computer is running OK, then there isn't really a thing you need to do except repair the hard drive and permissions before installing any new system updates.

Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
• I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
I know that using a cloned drive would work well in this instance.
I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive?

You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that this Internet criminal has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. This failure of oversight has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as Lion Cache Cleaner, TinkerTool System, OnyX, or Cocktail that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
