McAfee users receiving the error message, "Update Problem: McAfee cannot update your software. Please check your Internet connection. If the problem continues, please contact Technical Support." shouldn't panic if the error message does not occur all the time.
This problem with installing virus definitions for McAfee should go away when you try again at later or different time. Traffic or connection to some websites or servers failing -- especially if there is ongoing maintenance in the server side -- is a common issue. However, if updating McAfee software continues to display the said error message, you should use below steps to troubleshoot or fix the problem:
Manually download the virus signature files (DAT file) from McAfee website.
- Save the DAT file e.g. 6267xdat.exe in temporary location e.g. Desktop.
