Recently I noticed that on Ticketmaster.com when I put in the zip code , etc I would only get the moving circle that says "loading". The information won't load. On Amazon.com I noticed that in certain areas of the page information is trying to load but can't for some reason. I just see the circle with the word "load". Does anyone know what might have happened or what I can do to fix this?
Thanks in advance for any ideas or suggestions!

This could be something simple as corrupt cookies, a security setting, or malware infestation.

You say Ticketmaster and Amazon and when entering "personal" information. Does this problem only occur with secure connections? That is, when you see the padlock indicating you have established a secure (SSL) connection?

I would suggest you clean out your temp files and clutter, then scan for malware. Below is my canned text for a quickclean, but I recommend you update your own security tools and run a complete scan too.

Have you thoroughly scanned for malware? Just to be sure, I recommend purging the hard drives of clutter with Windows (XP, Vista or 7) Disk Cleanup, ATF Cleaner or CCleaner. If using CCleaner, uncheck the option to install the Yahoo toolbar during installation. Before first use, go to Options > Settings > Advanced and ensure Only delete files in Windows Temp folders older than 24 hours is unchecked. Know your site credentials (user names and passwords) for sites you frequent before cleaning; you may have to login again at next visit.

Download and install Malwarebytes's Anti-Malware (MBAM) and scan as follows:

Check for updates before scanning,
Select Perform quick scan > Scan,
When complete, click OK, then Show Results,
Ensure all is selected, and click Remove Selected,
When complete, save the log in Notepad to a convenient place for future reference.

Repeat for all computers in the "Trusted Zone" of your network (your side of the Internet "gateway" - typically the cable or DSL modem).

Windows Disk Cleanup Note: One distinct advantage Windows Disk Cleanup has over all other cleaners is that it also has the option to delete all but the most recent Restore Point. This can be significant as malicious code can hide there too. But I caution this option, found under the More Options tab, should be used only after careful consideration. If experiencing a problem that first appeared within the last couple days, do not use this option until sure System Restore can not be used to fix it. If the computer is running fine otherwise, and you are doing your weekly supplemental scans and want to root out as many potential malware hiding places as possible, I recommend setting a new Restore Point, and then use this Disk Cleanup option to clear out the old points.
