Updates Not Downloading; DAT Out of Date

My Updates will not download when I try to manually download them. Ran McAfee Virtual Tech, which said DAT file out of date and Security Center not working. TRIED to access Live Chat and after several tries / long waits and no chat person coming online, I gave up.

Is there any way to resolve these issues without uninstalling/reinstalling? On Windows Vista Laptop with Security Center 2010. thanks.

Please let me know the type of internet connection that you are using(Dial Up, DSl, FIOS, Wireless..), default Internet browser(Internet explorer, Firefox...), and let me know whether if you are using any other third party AntiVirus applications or not?

Re: Updates Not Downloading; DAT Out of Date

HI, thanks for trying to help.

I'm on a PC laptop using Windows Vista connecting to the Internet via a home office wireless router, using Internet Explorer 7.

I have no trouble connecting to the Internet and I can run my McAfee Virus Scan. However when I click "Check Updates" nothing happens. McAfee Security Center tells me my computer is "up to date" but I can't download the updates, it just freezes at 0% completed.

No other third-party anti-virus software on this computer.

Please let me know what to do next. Thanks!

Hello there,

Click the Windows Button and type drivers into the search bar and press enter

Among the folders that appear, select the folder name "etc".

Right click on hosts and select open with - Select Notepad from the list.

Make sure that the last line contains - local host.You can delete if any additional entries found below that and save the file.


Click the Windows Button and type cmd.exe into the search bar

Among the choices, right click on cmd and select Run as Administrator.

In the command prompt window, type ping download.mcafee.com and hit enter

Let me know if we get a reply from the website or any errors.

Delete all the entries under local host

Now save that file and close that.

On the command prompt window type ping download.mcafee.com

Check whether you are getting replies from any webserver or getting any error message.

Close that command prompt window and try to update McAfee.

Hi, thanks for trying to help.

I followed your instrux, went into drivers > etc > hosts ... local host is  Then I tried to delete the ::1 underneath it and Notepad wouldn't allow me to save the file, got an error message: "Cannot create the c:\Windows\System32\drivers\etc\hosts file; Make sure the path and file name are correct."

The cmd ping worked, 4 packets sent and received, 0% loss.

At this point would it be faster to uninstall and reinstall from the website? Thanks!

Thanks for getting back soon, I would say to have this fixed completely , please click on useful links at the top of this page and get in touch with our technical support chat technicians and they will find out if the host file is set right , if not they will help you in getting that fixed as well , as it might be one of the reason for the updates to fail.

Let me know if you still have any issues.

Hi, I did a System Restore and that seemed to fix my problems. Thank you everyone for your suggestions and assistance.
