Chrome says I have a virus on my computer

How can I run a diagnostic?

Chrome does not have the capability to determine whether you have malware on your computer or not. It could identify a malicious site and warn you not to go there, but it cannot warn you about having a virus.
Most likely what you are seeing is a pop-up on a web site that has been hacked, and that pop-up is trying to scam you into installing "anti-virus software" that is actually malware. (Most likely Windows malware, as there aren't any Mac malware scams behaving this way at the moment, to my knowledge.)
Can you provide a screenshot of the warning? Press command-shift-3 to take a screenshot, then click the camera icon in the toolbar of the post editor here and attach the resulting file (which will be found on your desktop).

There is Red Icon at the top bar and it says I have a virus and things keep popping up saying I have a virus and need to do a scan and pay for some sort of software to complete the scan, someone told me that this is a virus in. How do I get rid of it?

This could well be the notorious Mac Defender - which is an annoying program that tricks you into thinking that your Mac is infected with a virus, when the only infection is Mac Defender itself.
When surfing the web never EVER click on a link that says "Free anti-virus scan" or "Scan now" - they are nearly always scams which will end up infecting your computer. Although Macs are resistant to viruses, they're not resistant to user stupidity.
If you Google "Mac defender" then you'll find plenty of sites with instructions on how to remove this minor nuisance. Take this as a warning that you need to be more careful in your surfing habits.

Popup Saying You Have a Virus

I am an active student of the University of South Florida and I went to log in into their student portal MyUSF and after validating my credentials, a pop-up shows saying I have a virus. I have tried to log in with all my Mac computers and it shows the same thing.
Any suggestions on why this may be happening?

It may be, but in one of those login attempts, my password was reset and I was unable to login. i did not change my password though. It is why I suspected that the popup may have been an indication of that but now that you say it is a reminder to not click in popups makes sense, however I do not know why my account got my pass reset.
Thank you!

I have a pop up saying i have a virus. I dont feel comfortable buying a antivirus on here. What should I do?

Shortly after starting up, a dark 'film' slowly comes down over the screen and I get a message saying I have to shut down the computer. I've tried to start from the disk, and before I can even run a repair off utilities, it happens again. What's up?

When I started my iMac today, it started beeping like an alarm horn. I shut it down, and held the startup button a little longer to get it to start. Shortly after starting up, a dark 'film' slowly comes down over the screen and I get a message saying I have to shut down the computer. I've tried to start from the disk, and before I can even run a repair off utilities, it happens again. What's up? Am I screwed? HELP!!

What you are seeing is a kernel panic, often but not always connected with a hardware or peripheral issue, so, unplug everything except mouse and keyboard, reboot and hold the shift key as soon as your hear the chime, continue holding it until you see the Apple Icon and spinning progress indicator, then post back.
It will take noticeably longer than normal to start.

When i click on my external hard drive the screen goes dark and a msg pops up saying i have to shut down my computer by holding the power button and then restart it. when i do that i get the same result every time. it worked perfectly last night..

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Ifou don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.
I know the report is long, maybe several hundred lines. Please post all of it anyway.

I have a new macbook pro running lion and want to update the software on my ipod touch. My old macbook ran 10.4.11 and won't update - but the new computer says I have to update on the computer I normally sync on or my music will be lost. Solution?

I have a new macbook pro running lion and want to update to ios 5 on my ipod touch. My old macbook only has 10.4.11 and can't be updated to lion - and won't update my ipod touch to ios 5. But the message on my new macbook pro says I have to update on the computer I normally use for syncing or my music will be lost. Is there any solution for this?

try exporting your iTunes libary from the old computer to the new one
take a look at this from apple

Have a virus on my computer

I have a virus on my computer need your help to get rid of it so I can download for netflix please

MalwareBytes is an excellent tool, however, since this is a Microsoft Forum I recommend the Microsoft Malicious Software Removal Tool :)

Microsoft Malicious Removal Tool is great but it won't remove all malwares and it doesn't contain removal for all malwares. It is better to use Safety Scanner which contains removal for all malwares which are being detect by Microsoft Anti-Malware technology:

I just got a "warning system may have found viruses on your computer" message on safari

I just got a "warning: system may have found viruses on your computer" message on safari that mentioned system may have found 2 malicious viruses: Rootkit.Sirefef.Spy and Trojan.FafeAV-Download. Also a phone # to call for help in removing the viruses. I have a MacPro I don't know if this is for real or spam. I had to force quit safari and turn off and then back on my computer but when I clicked on safari again the message was still poping up. Does anyone know and can anyone help me? Thank you.

Fraudulent spam. Not only is it impossible to diagnose your computer's health, virus status, etc, by visiting a web page, Macs don't get viruses of that kind. Calling that number would have prompted the perpetrator to take your money and/or gain remote access to your computer.
Quit Safari completely by holding down your cursor on the dock icon and choosing Quit when you see it appear, or hitting cmd-Q when the Safari menu is visible on the top left of the screen. Once it has completely quit (there is no light under the dock icon), hold down the Shift key on the keyboard, and launch Safari again.
Safari will normally try to reload whatever webpages were open when it last quit; holding Shift will cancel this behaviour. And try to avoid going back to whatever webpage you were on when you got the popup.

New itunes update wont download and now I am told to reinstall itunes using "tool". That doesnt work. Says I have no itunes on my computer. Is it ok to uninstall and then reinstall?

Notified there is an update to itunes. Downloaded it, now I have NO itunes on my computer. Went to tools as asked to do so manually. Still nothings. Is it safe to uninstall and then reinstall itunes? And has anyone else experienced this.

Hello janrk,
I would recommend following through the uninstall and reinstall procedure. The following articles provide steps for this, and other troubleshooting that can help get iTunes installed and stabilized.

HT1277 i have an imac and my cable company has stopped my emails because they say i have comp virus..... thought macs don't get them ***???

I am told by my cable company that my email has a virus so they stopped my emails. How do I do a virus scan on a mac thought they didn't get viruses?

It is entirely possible for an iMac to acquire and host malware; to be infected with what's often called (sometimes technically incorrectly) "a virus".
This can be due to malware that was explicitly installed and authorized by an administrative user, or can be due to vulnerabilities in existing OS X software. Recent vulnerabilities that can affect OS X users include those encountered in Safari, in Oracle Java, or in Adobe Flash, among other components.
One of the most common paths for infection are explicitly-requested downloads, and that have then been authenticated by an administrative user. Basically, a user that's been convinced to download and install and use an administrative password to authenticate the malware installation. These have been seen with "video players", for instance, where a user downloads and installs an updated player; claimed to be Adobe Flash Player or some other CODEC or player component.
There are other malware attacks possible. Trojan horses have been seen targetting OS X, for instance.
Depending on the details of the actual infestation here (if there is any infestation here, of course), it is possible for an ISP to spot an infected computer through various available monitoring mechanisms. Your OS X client system could be sending out mail messages directly through protocols that are server-oriented protocols (a rogue SMTP spam engine has been installed on your OS X client, for instance), and that outbound SMTP traffic can be easy to spot at a firewall or network monitor. It's also possible to spot malware in the attachments in outbound messages that are routed via the ISP's mail servers, as well; various ISPs will scan messages.
The first step is to determine if your system has unauthoriized malware installed. Ask your ISP for what evidence they have for this infestation; what evidence they believe they've found. It's also possible that you'll need to purchase anti-malware tools, or (depending on the particular severity of any infestation found) reinitialization and restoration.
It's also possible for another system on your local network to be infested. Windows boxes, Linux and even printers can become infested these days.
And it's possible that you've received an infected document from somewhere, and have been working on it on OS X; that your system is hosting the malware, but that it's not actually infected. (OS X, Linux and Unix file services can all host Windows malware easily, for instance, but those systems generally can't be infected by that particular malware.)
And the ISP could be incorrect in their particular report to you.
You'll probably need some help determining if this is a real malware infection, and then cleaning up the problem; somebody with some more experience in interpreting what the ISP has found, and in determining whether that indicates a problem with your OS X system, and then (if so) how to resolve it. That might be somebody at the Apple Genius bar, or a local Apple specialist.

When I open Safari a web site appears saying I have a virus

The message is as follows:
System has Detected Security Error, Due to Suspicious Activity and Network Firewall seems to be Turned Off. System Might be infected with Trojan BackDoor.Flashback. Please Contact Support - Certified Live Technicians For Help 1(844) 291 9491 and a website http://www.rremail.in/
I cannot move off this site or use safari. I can write this question by using google Chrome. How can I clear this off my computer?

Choose Force Quit from the Apple menu, close Safari, and then launch it with the Shift key held down. If that doesn't work, temporarily disconnect the computer from the Internet.
If that message continues to appear, click here and run Adware Medic.

Gmail and Yahoo mail say I have a virus

I typed a letter using Microsoft Word (Office 2004, Word version 11.0.0). The Word document would attach to an email in both Gmail and Yahoo email, but neither would send the email (with attached word document) and both said a virus was present. I downloaded ClamXav and scanned Office 2004; no infected files were found. I then scanned the document in question, and Clam Xav said it was infected. What does this mean, and what should I do next?

Hi, sometimes email providers just block some kind of documents. My suggestion is: compress the file in .zip or .rar format and try to send it again... it should work.
Let me know, bye

I am trying to download the WSJ app the iPad says I have yo sync with my computer...I do not have a computer..any ideas

I am trying to renew and download my WSJ apple. The iPad tells me I must sync to my computer...I do not have a computer..Any ideas?

Update your software. The WSJ app has been updated and requires 4.2 at least. Your signature says you are running 4.1.
And you do NOT have to have a computer to buy apps. I only synch in order to backup once in a while. But you DO need one to update your iPad software. So either find a friend or wait until IOS5 for the OTA updates. I don't know if the Apple store can help you or not. Someone else might know if they would update your software for you.
