Do I have a virus on my Mac
I have a ibook 1.33 ghz PowerPC one and this has Mac OSX 10.5.4
Since the last few days, I see that the icons on my dock are getting deleted automatically and so are the files in Mail.app. I seem to have lost a lot of emails and the itunes playlist is all gone.
On another login, the system automatically deletes files from the desktop and logs off. The only reason I can think of is that it is a virus. I tried running Intego's AV software but it was not able to pick up anything.
Has anyone encountered such a virus?
Thanks for all the help
Cheers

Welcome to Apple Discussions:
There are no viruses for the Mac. Your scan shows this.
There is malware and other things that can be at issue.
Do you use any file-sharing software such as Limewire or other bit-torrent stuff?
I suggest first running the disk utility and repairing your HD and permissions.

every time i click on a link another random link pops up in a new window. Does this mean i have a virus on my mac?
No; it means that the computer has adware. Click here and follow the instructions, or if there’s a type of adware not covered by them on the computer, these ones. If you're willing to use a tool to remove it(you don't need to, but may find it easier), you can instead run Adware Medic; this link is a direct download.

Do I have a virus on my Mac Air because I keep getting ads for MacBooster and MacKeeper?
Do I have a virus on my Mac Air because I keep getting ads for MacBooster and MacKeeper?
You may have installed the "VSearch" trojan. Remove it as follows.
Malware is always changing to get around the defenses against it. These instructions are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
Back up all data before proceeding.
Step 1
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot," "Trovi," or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
Reset the home page and default search engine in all the browsers, if it was changed.
Step 2
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchAgents/com.vsearch.agent.plist
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "com.vsearch.agent.plist" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
Restart the computer and empty the Trash. Then delete the following items in the same way:
/Library/Application Support/VSearch
/System/Library/Frameworks/VSearch.framework
~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin
Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
The problem may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow.
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 the Internet criminal behind VSearch 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.
*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 won't see what you pasted because a line break is included. Press return. -

OK to have separate virus progams in Mac and in Windows?
I am advised to have virus protection in the Windows XP program I have just installed in Parallels. I already have McAfee Virus Scan on my Mac. Is it okay to load in the McAfee Virus Scan software for Windows into Windows? I saw a warning about having two virus programs operating on the same computer, and just want to make sure this will not be a problem. Thanks
Hi Barbara,
Since the Windows version of McAffe Scan will only scan inside your Parallels Windows and not the OSX side, it is safe to do what you do/have.
Besides quite a lot are using two or more Virus Scanner with their Windows as long as only one is running as 'On-Access Scanner' and the others are used as 'On-Demand Scanner'.

I think I have a virus on my mac, how do I get rid of it?
For the last few weeks, my mac has been working very slowly. I heard it might have a virus. Does anyone know how to find out if you do have a virus and how to get rid of one on a mac?
There are no OS X viruses. If your computer is running slow it's not because of a virus. You might see the following:
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 TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 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. -
Hello Last night while watching a video on Facebook a pop up window said I had a virus and to clean it click on the link. I did so and followed a prompt or 2 and then I thought this was a scam so I stopped. However I looked at my download file and it shows Mackeeper listed 4 times. Does this mean I have installed MacKeeper and if so does this mean I have installed some sort of malware/spyware or problems for my computer hence for myself.
Thank you for your help

Do I have a virus? My Mac is acting very strangely
There are lots of strange things happening with my mac.
When I first got this mac, everything was fine. Then I had a run-in with someone who I suspect tried to or did in fact hack in to spy. There was one instance when it seemed to me like someone was using remote access to move around windows and open files right in front of me.
Anyway, long story short, this person is no longer a concern and I have since tightened security, enalbled my firewalls and installed a VPN.
But...here are just some of the problems I have noticed.
When I power up, sometimes the log in window appears with only the text box visible, the rest of the screen is black. At times, when I move the mouse over the screen, it leaves a trail behind that 'erases' the black screen to reveal the log in screen behind. Sometimes part of the screen is black and some of it is not.
Sometimes, when I power down, my mac turns itself back on again, even though the lid is shut. It sits there on sleep until further notice.
When I walk away, leaving my mac to turn on the screen saver and then go to sleep, sometimes when I wake it up again, all of my applications have quit. I have to open eberything again and sign back in, very annoying! In these situations, my wi-fi has quite often also been turned off. When I turn it back on, it asks for my network password again, but then does not recognise it when it is entered. I have to restart before I can connect again.
I've ran disk uitility checks and everything appears fine, I've also installed Trend Micro Titanium virus protection - it's scanned all my files and has detected nothing suspicious.
Sometimes I have wondered about the functionality of my VPN? Maybe it is the problem? I often turn it off because it slows down my page loading.
If anyone has any help or advice, I'd be ever so grateful...!If you know or suspect that a hostile intruder has either had physical access to your computer, or has been able to log in remotely, then there are some steps you should take to make sure that the computer is safe to use.
First, if there's any chance that the incident will be the subject of legal action, then you should do nothing at all without consulting a lawyer or the police. Your computer would be the principal evidence in such a case, and you don't want to tamper with it.
Running any kind of software to scan for "viruses" or "rootkits" is worse than useless. If I broke into your system and wanted to leave a back door, I could do it in a way that would be undetectable by those means — and I don't pretend to any special skill as a hacker. You have to assume that any intruder could do whatever I could do. The "anti-virus" software itself will slow down and destabilize the computer with no offsetting benefit.
The only way you can be sure that the computer is not compromised is to erase at least the startup volume and restore it to something like the status quo ante. The easiest approach is to recover your entire system from a backup that predates the attack. Obviously, that's only practical if you know when the attack took place, and it was recent, and you have such a backup. You will lose all changes to your data, such as email, that were made after the time of the snapshot. Some of those changes can be restored from a later backup.
If you don't know when the attack happened, or if it was too long ago for a complete rollback to be feasible, then you should erase and install OS X. If you don't already have at least two complete, independent backups of your data, then you must make them first. One backup is not enough to be safe.
When you reboot after the installation, you'll be prompted to go through the initial setup process for a new computer. That’s when you transfer the data from one of your backups in Setup Assistant.
Select only users in the Setup Assistant dialog — not Applications, Other files and folders, or Computer & Network Settings. Don't transfer the Guest account, if it was enabled.
Reinstall your third-party software from original media or fresh downloads — not from a backup, which may be contaminated.
Unless you were the target of an improbably sophisticated attack, this procedure will leave you with a clean system. If you have reason to think that you were the target of a sophisticated attack, then you need expert help.
That being done, change all Internet passwords and check all financial accounts for unauthorized transactions. Do this after your system has been secured, not before. -
Virus in my macbook pro - how do I sort it?
There are no viruses affecting OS X. See:
Helpful Links Regarding Virus Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
If you require anti-virus protection I recommend using ClamXav.
I would first get rid of Mac Keeper: How to Remove MacKeeper. Next look for other things that may cause your computer to run slower:
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility 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; Disk Warrior 4.x is now Intel Mac compatible.

Additional Hints
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.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file. -
I think I have a virus on my Mac - Please help!
I've had my iMac for about a year now. In the past few weeks however I have noticed that it is beginning to freeze and run more slowly. I'm getting messages that my startup disk is almost full and when I look at my hard drive, it shows that it is almost full- which is impossible. Also, since today, Safari won't work properly: When I try to open it, hundreds of safari windows open and the whole computer crashes. I downloaded ClamXav from the internet and I ran it and it showed several files which were infected and I deleted all of them. However, I'm pretty sure the problem runs deeper than that. What should I do now, are there any programs e.t.c. which I can download which will rid my computer of the virus?
Thanks in advanceI doubt what you are desribing is a Virus, more likely it's a runaway Log. Here are a few things to work through before you get off into the weeds with chasing a phantom virus.

I think I might have a virus on my mac, what should I do?
So I downloaded this thing that told me if I downloaded it, I could watch a TV show I was looking for
on it (ridiculous, I know) but ever since, I get these boxes that'll pop up on every site I go on (except for maybe facebook) and they display adds, it also will use certain words on a site and make them into links to send you to other sites or whatever that are irrelevant. I've attached a picture of what it looks like, it happens on netflix especially, every single time. I used a virus finder and tried to delete everything it found that was suspicious but its still going on, should I just wipe my whole computer back to factory setting?There is no need to download anything to solve this problem. You installed the "Flashmall" trojan. Take the steps below to disable it.
Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.
Back up all data before continuing.
1. Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
~/Library/LaunchAgents
In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return. A folder named "LaunchAgents" will open.
2. Inside the folder you just opened, there may be files with a name beginning in any of the following ways:
com.crossrider
com.extensions
com.flashmall
com.webhelper
com.webtools
flashmall
UpdateDownloader
WebSocketServerApp
Some of these files may be absent. Move any that you have to the Trash and close the Finder window. Log out or restart the computer. The trojan will now be inactive, but there are a few more components of it that should be cleaned up.
3. Do as in Step 1 with this line:
~/Library/Application Support
A folder named "Application Support" will open. Inside it there may be a subfolder with this name:
webHelperApp
If so, move that subfolder—not the "Application Support" folder—to the Trash.
4. Open this folder in the same way as above:
~/Library/ScriptingAdditions
and remove an item named
BrowserHelper.osax
if present.
5. Open this folder:
~/Library
Look for subfolders with either of these names:
flashmall
WebTools
and move them to the Trash, if present.
6. Open the Applications folder. If it contains an item named "Flashmall" or "WebTools", move that to the Trash.
Empty the Trash. -

How do I get rid of viruses on my mac?
Hi,
I have ran a speed test on my internet connection and it is currently at 0.48, I believe that I may have a virus in my mac. I have had a technician from my provider test the line and the speed on his laptop was 8.45.
What is the best free program that I can get? Or do I have to fork out money for an antivirus program?
thanksAre you using WI-FI? If you are, option-click on the Airport icon. What is the Transmit Rate showing there?
To enter new DNS numbers (Sys Prefs>Network>Advanced) click on the + button. You will get a new field in blue, as shown in the screenshot below. Enter one number there, then hit OK. You will be brought back to the main tab. Hit Apply. Go back to Advanced and repeat for the second number, then hit OK. You will be brought back to the main page and hit Apply again. You can reorder the way the numbers appear by dragging them. Not absolutely certain of this, but the numbers first listed will be the DNS servers used first; second will be contacted next. If you put all those numbers in (all three sets), you can then test which servers are the fastest for you by rearranging the list order.
DNS (Domain Name Server) is like the phone book. It translates names into telephone numbers. You can't dial a name. DNS servers translate site names into numbers. Some servers are better/faster than others.
Also be sure to turn off IPv6 in TCP/IP
To check that OpenDNS is working, go to http://www.opendns.com/welcome/

I have a virus on my macbook air WHAT DO I DO?
Okay, so when I was in Brazil... i used netflix online and i would download pictures online from tumblr and stuff. Then a week or two after I got to Brazil my FaceTime, app store, itunes, and mail wouldnt work. My photo booth would be very slow as well. I told my mom to check and see what was wrong with it becasue she works in computers, and she said that I many have a virus on my mac...honestly i don't know how this happened I thought macs werent supposed to get viruses?! PLEASE HELPP.
P.S. my one year apple care warranty isnt up yet...Its extremely unlikely you have a Mac Virus, there arent any out there spreading amongst Apple computers.
You said----FaceTime, app store, itunes, and mail wouldnt work.
What changed in Brazil? I assume a much slower internet connection.

Hi -
I'm a long time Mac user (currently using MacBook Air) but not so tech suvvy and unfortunately, so as my husband who is non Mac user.
My husband has this Dell laptop and had some issue with his computer and had paid for the help support from one of the MS certified technitians. Recently, this technitian guy called my husband and told him that his paid support service is just about to expire and encouraged him to renew the service. Before my husband decide to renew this contract, he told this guy to check his computer. And he found that my hubby's computer got viruses (of course, he has virus protection software from well-known company installed on his computer...). This is okay, I get that... BUT the technitian guy ran the diagnosis and found out that our home network also got viruse! and thru that network my Mac also got virus, he says.
As far as I know, my Mac runs fine. I know, basically, we don't really need to install any virus protection s/w on Mac unless you really want to. And I'm very caucious, so I don't download any suspecious things or don't access to any suspecious website, too. So it's really hard for me to believe what this guy says. SO, here's what I really want to do; Is there any way to check if I really have any virus on my Mac other than just to see anything acts funny? Another question, how can I check, if our network (only my husband computer and my Mac are connected to this network) is really infected by any virus? And more importantly, if they are inected, is there any way to fix it?
I really don't know, if this MS certified tech guy is telling me the truth or just lip sink (or even a lie!?) to make my husband to renew his service... My husband expects me to make a decision but with my limited knowledge (which unfortunately, more than what my husband knows... ah...). And moreover, I'm stunned by the fact (or totally lie) that my Mac has virus!!! Need your experts help!!!BUT the technitian guy ran the diagnosis and found out that our home network also got viruse! and thru that network my Mac also got virus, he says.
He 'didnt tell the truth'. Ask him to name that virus.
Currently there are no genuine Mac virus' out in the wild woods of the net
