So, bit defender and other virus scanners not find any viruses or malware...this alert from Mac Keeper are true or not? how i can know this is fake or true? thanks for your answers. The best regards

The pop up messages are nothing more than annoying spam. Have you installed MacKeeper? Are you constantly seeing these popup messages? If so:

Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
Fix Some Browser Pop-ups That Take Over Safari.
Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
Quit Safari
Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
Relaunch Safari
If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

If you require anti-virus protection Thomas Reed recommends using ClamXAV. (Thank you to Thomas Reed for this recommendation.)
From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect everything targeting the Mac.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.

Mac book air , antivirus?

got a mac book air for the first time, before a PC. Does that need anivirus too??

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files. This feature is transparent to the user, but internally Apple calls it "XProtect." The recognition database is automatically updated once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders. In most cases, there’s no benefit from any other automated protection against malware.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
Gatekeeper has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could conceivably get control of a code-signing certificate under false pretenses (though there's no evidence this has happened yet.) The certificate would eventually be revoked, but probably not before some damage was done.
For more information about Gatekeeper, see this Apple Support article. 4. Considering all the above, the best defense against malware is your own intelligence. All known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. If you're smarter than the malware attacker thinks you are, you won't be duped. That means, primarily, that you never install software from an untrustworthy source. How do you know whether a source is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn users who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
“Cracked” copies of commercial software downloaded from a bittorrent are likely to be infected.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. No intermediary is acceptable.
5. Java on the network (not to be confused with JavaScript, to which it's not related) is a weak point in the security of any operating system. If a Java web plugin is not installed, don't install one unless you really need it. If it is installed, you should disable it (not JavaScript) in your web browsers. Few websites have Java content nowadays, so you won’t be missing much. This setting is mandatory in OS X 10.5.8 or earlier, because Java in those obsolete versions has known security flaws that make it unsafe to use on the Internet. The flaws will never be fixed. Regardless of version, experience has shown that Java can never be fully trusted, even if no vulnerabilities are publicly known at the moment.
Follow these guidelines, and you’ll be as safe from malware as you can reasonably be.
6. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability and poor performance.
By modifying the system, the software itself may create weaknesses that could be exploited by malware attackers.
7. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so can corrupt the Mail database. The messages should be deleted from within the Mail application.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. If you don't need to do that, avoid it. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
8. The greatest danger posed by anti-virus software, in my opinion, is its effect on human behavior. When people install such software, which does little or nothing to protect them from emerging threats, they get a false sense of security from it, and then they may do things that make them more vulnerable. Nothing can lessen the need for safe computing practices.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use.

How do i get more memory on my mac book air? is says that i can add 2 more gig how?

how do i get more memory on my mac book air? is says that i can add 2 more gig ??? or wat files can i delete

Macbook Air memory is soldered to the logicboard.
You can only get 4GB or 8GB (2012 Models) in the Air when you order it that way. Otherwise, you're stuck with 2GB.
Unless you're talking about hard drive space - then it is upgradeable - click HERE to see which one corresponds to your model.

I have a mac book air 11". When I boot up connected to the huge Thunderbolt screen it detects the detects the fact and gives me great quality. now I am travelling away from the scree it boots up, nice picture, then switches to rubbish resolution.

I have a Mac Book air 11". Normally at home I connect this to a large Thuderbolt Screen. When booting up it some times gets confused and offers me a low resolution result, but some plugging and unplugging of the screen fixes this. I assume it sometimes "sees" the big screen and sets the resolition accordingly. Sometimes does not. But now... I am away from big screen and cannot get the Macbook air on its one to deliver anything other than really poor resolution. I ahve done displays and chosen all three - but no better. And I have said Choose the Best ONe... again not luck. Any ideas. I read in back posts this was a problem a few years ago.

Welcome to Apple Discussions
I believe you have a failing GPU (aka Video Card). Run AHT and see what it tells you. Do not be afraid to run it up to three times in succession if at first it does not detect an error (sometimes errors that are caused by overheating will not show up until the computer is stressed enough - repeating AHT will do that).
As an aside - the MBA was not designed to take the place of a desktop. If you are powering your MBA by leaving it permanently attached to the thunderbolt port on the monitor you are shortening your battery life.

I recently purchased a time capsule and thought I would put my itunes on it as an external drive as my mac book air only has 120gb. However I can not be connected to the internet and the TC at the same time in order to download the files to the TC. Help?

I recently purchased a Time Capsule and put my iTunes library on there so that I wasn't using up my hard drive space. Only 120gb on my mac book air. However when I download songs from iTunes I can not be connected wirelessly to the internet at the same time. Can I hard wire my TC in to my mac so that I can treat the TC as just an external hard drive? Thanks

Initially, you asked if you can hardwire your MBA to the TC. The answer is yes, by using the optional USB Ethernet adapter that Apple provides. However, in order for your MBA to access the TC's internal or USB-attached HDD, it would need to establish a network connection to it. This would be true of any NAS device on an Ethernet network. Therein, lies the problem. Your MBA cannot connect to two networks simultaneously.
One option then, would be to have two separate iTunes Media folders; one on the MBA & the other on the TC. This way, you can download the music to your MBA when connected to the Internet at the AirPort lounge, and then use iTunes Consolidate Library feature to transfer the audio files to the TC's iTunes Media Folder location. A great program to help maintain multiple iTunes Librarys and/or Media Folders, that you may want to consider, is PowerTunes.

Mac Book Air shuts down completely if I close the cover and leave for hours. Message: you shut down your computer because of a problem. Any thoughts what is happening?

Mac Book Air shuts down completely if I close the cover and leave email running. Is n't it supposed to just sleep and awaken whe the cover is reopened? Instead, I have to boot it. Any idea what the problem is? I am unaware of any problem, just close the cover for safety.

Well I don't know anyone that closes the cove and leaves it for Hours... But try going to System Prefrences > Energy Saving > Uncheck Put Hard Disk to Sleep.

Your advice did not help me. I also installed 10.7.4 combo but the situation is the same.
my internet connection is ok, mail is ok, but app store after 3 resets does not recognize my ID and it says "connection is not possible". Why? I have the same problem in both my mac mini late 2009 and mac book air 2010? Is it a problem of 10.7.4 update? I have to solve this problem and how can i return to 10.7.3 if my last backup was not with 10.7.3???thank you for your kind collaboration...
