I have a virus on my macbook.

I have the iAntivirus and it was working great for two years. my trackpad is affected and i am unable to quit safari. I know my computer was affected on 12/7 because that's the last time the antivirus was able to work. Is it too late for my mac? What else could the problem be? where is the best place to get it fixed? There's a best buy near here. Any other suggestions?

Third - there are no viruses for osx

The update alerts are fake, and are intended to dupe you into installing malware or disclosing private information so that your identity can be stolen.
You might get the alerts when visiting a website that has been hacked. Don't visit the site again. If applicable, notify the site administrator of the problem, but don't send email to an unknown party.
If you get the alerts when visiting more than one well-known website, such as Google, YouTube, or Facebook, then they may be the result of an attack on your router that has caused you to get false results from looking up the addresses of Internet servers. Requests sent to those sites are redirected to a server controlled by the attacker. It's possible, but less likely, that the DNS server used by your ISP has been attacked.
Back up all data.
Unlock the Network preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Cllck Advanced, open the DNS tab, and change the server addresses to the following:
          8.8.8.8
          8.8.4.4
That's Google DNS. Click OK, then Apply.
In Safari, select
          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If you’re using another browser, empty the cache. Test. If the fake update alerts stop, see below. Otherwise, ask for instructions.
The router's documentation should tell you how to reset it to the factory default state. Usually there's a pinhole switch somewhere in the back. It may be labeled "RESET." Insert the end of a straightened paper clip or a similar tool and press the button inside for perhaps 15 seconds, or as long as the instructions specify.
After resetting the router, quit the web browser and relaunch it while holding down the shift key. From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Do the equivalent if you use another browser. Open the Downloads folder and delete anything you don't recognize.
Then go through the router's initial setup procedure. I can't be specific, because it's different for every model. The key points are these:
1. Don't allow the router to be administered from the WAN (Internet) port, if it has that option. Most do.
2. Set a strong password to protect the router's settings: at least ten random upper- and lower-case letters and digits. Don't use the default password or any other that could be guessed. Save the password in your keychain. Any password that you can remember is weak.
3. If the router is wireless, or if you have a wireless access point on the network, use "WPA 2 Personal" security and set a different strong password to protect the network. If the router or access point doesn't support WPA 2, it's obsolete and must be replaced.
During the time the router was compromised, you were redirected to bogus websites. If you ever connected to a secure site and got a warning from your browser that the identity of the server could not be verified, and you dismissed that warning in order to log in, assume that your credentials for the site have been stolen and that the attacker has control of the account. This warning also applies to all websites on which you saw the fake update alerts.
Check the router manufacturer's website for a firmware update.
If you downloaded and installed what you thought was a software update, ask for instructions.

I think I may have a virus on my MacBook laptop, ran disk utility, "filesystem verify failed." Help!

I'm running a MacBook laptop and thought I might have a virus b/c i was browsing online a couple of days ago when i clicked on a link that appeared to automatically start downloading a file. I tried to stop it from downloading by clicking "cancel" in the downloads box that came up, but it compleatly downloaded before i could hit cancel. No programs automatically opened and started runnning (that i could see), but I've noticed slow browsing since then.
I ran the disk utility, "verify disk," to see if there were any problems. It came back with this error message: "First aid failed: Disk Utility stopped verifying "Macintosh HD" because the following error was encountered:
Filesystem verify or repair failed"
The text is black inside the verifying history box until the last three lines, which say in red:
"Invalid node structure
Volume check failed
Error: Filesystem verify or repair failed."
Does this mean I have a virus? Are there other things I can do to confirm that I do or do not have a virus? How do I fix this problem?
I'm running Mac OS X 10.5.8.
Many thanks for your advice/comments in advance.

Probably because the directory on the disk is corrupt.
The error "invalid node structure" is one that will take either DiskWarrior or a reformat to fix.
It has not to with any malware.

I have a virus on my macbook pro. Can I somehow reset my computer to get rid of it?

I have a MacBook Pro, OS X 10.9.4 (purchased late 2011). I am certain I have a virus. I was wondering if it is possible to reset my computer back to factory settings to get rid of the virus? So far I have removed/deleted photos and documents I have created, but I am afraid to delete a file that might be important.

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.
You can take Lincs expert advice on your mac running slow on this thread:
https://discussions.apple.com/thread/4520221?start=0&tstart=0
No worries about any virus.

I believe I have a virus on my macbook pro and do not know how to get rid of it.

Well I was being stupid and trying to get free gems on clash of clans so i did the stupid little surveys and that is most likely where I got the virus from. Never doing that again. When ever i go onto google chrome or any browser a random page pops up about mac protector or something and when I try using ovoo, it instantly backs out and I cannot use it. so i do not know what to do and i am not sure if i am using ios 8.1.1 or 8.1.2. i have a macbook pro that i got 3 years ago

There is no need to download anything to solve this problem. You may have installed a variant of the "VSearch" ad-injection malware.
Malware is always changing to get around the defenses against it. These instructions are valid as of today, 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 a more recent discussion, or start a new one.
The VSearch malware tries to hide itself by varying the names of the files it installs. To remove it, you must first identify the naming pattern.
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/LaunchDaemons
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 "LaunchDaemons" may open. Look inside it for two files with names of the form
          com.something.daemon.plist
and
           com.something.helper.plist
Here something is a variable word, which can be different in each case. So far it has always been a string of letters without punctuation, such as "cloud," "dot," "highway," "submarine," or "trusteddownloads." Sometimes the word is "apple," and then you must be especially careful not to delete the wrong files, because many built-in OS X files have similar names.
If you find these files, leave the LaunchDaemons folder open, and open the following folder in the same way:
/Library/LaunchAgents
In this folder, there may be a file named
          com.something.agent.plist
where the word something is the same as before.
If you feel confident that you've identified the above files, back up all data, then drag just those three files—nothing else—to the Trash. You may be prompted for your administrator login password. Close the Finder windows and restart the computer.
Don't delete the "LaunchAgents" or "LaunchDaemons" folder or anything else inside either one.
The malware is now permanently inactivated, as long as you never reinstall it. You can stop here if you like, or you can remove two remaining components for the sake of completeness.
Open this folder:
/Library/Application Support
If it has a subfolder named just
           something
where something is the same word you saw before, drag that subfolder to the Trash and close the window.
Don't delete the "Application Support" folder or anything else inside it.
Finally, in this folder:
/System/Library/Frameworks
there may an item named exactly
            v.framework
It's actually a folder, though it has a different icon than usual. This item always has the above name. Drag it to the Trash and close the window.
Don't delete the "Frameworks" folder or anything else inside it.
If you didn't find the files or you're not sure about the identification, post what you found.
If in doubt, or if you have no backups, change nothing at all.
The trouble 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. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Then, still in System Preferences, open the App Store or Software Update pane and check the box marked
          Install system data files and security updates (OS X 10.10 or later)
or
          Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

My MacBook Pro keeps on randomly scrolling on webpages, putting several spaces when I don't press the spacebar and only sometimes makes a space when I press the spacebar. Why is it doing this? Do I have a virus?

I am currently struggling to write this due to my very erratic spacebar. When I press it, it only creates a space about two thirds of the time. When I don't press it, it creates spaces, often several, in the middle of words. This is incredibly annoying and time consuming when writing. If I'm on iTunes or DVD player, it means the media is constantly stopping and starting.
When I am on webpages they will often scroll straight to the bottom, and when I try to scroll back up it won't allow me to and the screen will look like it's jumping, like my instruction for it to scroll up is fighting against an external instruction forcing it down. This 'fighting' effect is also seen with the spacebar issue when it makes several spaces and I press backspace to try and delete the spaces.
I have a MacBook Pro bought in July 2012 using Mac OS X 10.7.5. I use ESET Cybersecurity, which hasn't identified any viruses. I have deleted all internet downloads that aren't from well-known websites, yet the problem persists. It has been happening on and off for about a week, during which time I have turned the computer on and off many times, though today it has been far worse than before. I am worried I have a virus, though can't seem to locate one.
Please, if you can shed any light on the situation, please do! I'm not a techy person at all, so there may be a very obvious reason and solution for this, in which case I apologise for this waste of time. Still, any help would be very very appreciated, thank you!

You are still under warranty. Call Apple Care. Make sure you get a case number as all repairs have an additional 90 days of warranty.
#1 - You have 14 days from the date of purchase to return your computer with no questions asked.
#2 - You have 90 days of FREE phone tech support.
#3 - You have the standard one year Apple warranty.
#4 - If you've purchased an AppleCare Protection Plan, your warranty last for 3 years. You can obtain AppleCare anytime up to the first year of the purchase of your computer.
Take FULL advantage of your warranty. Posting on a message board should be done as a last resort and if you are out of warranty or Apple Care has expired.

I have just purchased a used MacBook Pro. Should I use a virus protection program on this computer? I can get Norton for free through my cable provider. Thanks, funkro

See my Mac Malware Guide.
This issue is more complex than some of the responses you have gotten are indicating. You definitely should avoid Norton, but there actually IS malware out there, and all anti-virus software is NOT "snake oil." Don't listen to anyone who tells you otherwise, as they don't know what they're talking about.
Although you should be able to do without anti-virus software just fine, there are some perfectly good reasons to install it and some good anti-virus apps to use if you decide to do so. Further, even if you do avoid anti-virus software, you need to understand what the threats are so you don't end up thinking you're totally safe and do something you shouldn't.

My MacBook Pro, 15 inch, purchased in 2006 may have a virus or perhaps has crashed. When I power it up, I get strange patterns. Nothing else loads. Is this a virus or has the hard drive crashed? Thanks.

When I power up my MacBook Pro, I get patterns. Nothing loads. Has my hard drive crashed or do I have a virus. I had been burning a DVD from an iMovie project on an external hard drive when problems began. Thanks for any insights.

Sounds like the video card is going, mine did that after I installed the P.O.S . OS X called Lion.
Was working fine under 10.6, little did I know that Cupertino was compromised at that time, likely the hackers corrupted the firmware updates.
Take it in, they will run their little test and say it's the video card and it's not worth spending $350+ plus whatever else you need to fix it.
Scrap it for parts and buy a new one.
However, you can extract the hard drive and use a SATA to USB adpater cable to the new Mac, transfer files manually or use Migration/Setup Assistant.

you'll need a tool kit too.

My MacBook Pro screen seems to be getting darker. It's hard to read at times. Is there a setting to make it brighter, or is this indicating I have a virus?

My MacBook Pro screen seems to be getting darker. At times it is very difficult to read....Is there a setting to make it brighter, or is it a sign that I have a virus or some malware?

Hi Cynthia
Go to the Apple Menu>System Preferences>Displays, you can adjust screen brightness there.

Does my MacBook Pro have a virus?

My mac's been acting very strange the past two days, it freezes up all of a sudden and sometimes an ad will pop up and it wont let me close it. What's a good/safe & reliable way to check if I have a virus on my laptop or not?

now i get a constant error about the disk
What kind of error is this? If it's a message saying that there's not enough free space, that's your problem. If your system drive gets too full, it will start having performance problems and can even start experiencing serious problems like crashes and data loss. The general rule of thumb is that you need around 10% of the drive free.
Do not try to clear space by using a "cleaning" tool, clearing caches, deleting language files or pre-installed applications, etc. Those are small-scale and/or temporary fixes that could have unanticipated side effects, including damage to your system. You need to delete personal files, either outright (if they are no longer needed) or after moving them to an external hard drive. One possibility would be to clear out your Downloads folder, if there's a lot of stuff in there.
If you have a lot of large files that you need and can't conveniently put any of them on an external drive, you can upgrade the hard drive to a larger one.
If the error message isn't one about free space, please give us the exact message so we can better assist you.

Does my mac have a virus?

Occasssionally over the last couple months while on the internet I notice this alert box that shows up it usually reads "about/blank.." followed by different combinations of numbers. It doesn't remain there long (i've tried to screen shot it) then dissapears. It will reappear and dissapear a couple more times and if I don't turn off my Airport controls and sever the internet connection it will eventually freeze my computer and I will have to power it off manually. I was told when purchasing the MacBook Pro that it did not need any virus protection software, however, now-a-days I realize Macs are more popular, therefore having a greater possiblity to be suseptable to newly developing viruses. My friend said I should download some AVG for Macs, which sounds good, but he's a PC man and I just wanted to check with you Mac professionals first!
Thank you, Tasha6797

You probably don't have a virus - what you may have are 'browser redirects' and you can read about them and how to prevent them at -> http://www.reedcorner.net/eliminating-browser-redirects-and-advertisements/.
Just in case you want to give your drive aa 'one-over' virus scan, I would recommend Sophos for Mac. It's good, free and comes with an uninstaller that actually works. Stay away from any commercial AV software as it tends to batter your system and can actually cause damage.
After you've done a one-time scan of your hard drive you can keep Sophos running or uninstall it - it's your call. I keep it installed just to scan my Downloads and email folders.
Good luck,
Clinton

I need to know if I have a virus or malware on my laptop. How do I do that?

Hello. I am new to this community and process so apologies for any errors in protocol. I have a MacBook Pro purchased in early 2011 operating with 4 GB 1333 MHz DDR3 for memory and using OS X Yosemite 10.10.2. Processor is 2.3 GHz Intel Core i5. This past week or so the computer has been slowing down, freezing up, and shooting up all sorts of pop-ups that flash and scream (literally; really loud). Do I have a virus or some sort of malware, and if so, what can I do about it?
Thanks for any assistance.
Scott

There is no need to download anything to solve this problem.
You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. 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. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.
