Browser tells me "Video Requires the lastest Flash Flash Player"

Question

I have a Windows XP system (with all latest updates installed)
Adobe Flash Player website tells me: "You have version 10,3,183,7 installed"
I have and use these three Browsers:
- Firefox 6.0.2
- Internet Explorer 8.0.X.X
- Chrome 13.0.X.X
I've been using this HP Pavilion laptop for 4 years now, and all this time have not had any problems looking at Flash content.  About a month ago, certain websites that use Flash will no longer work, regardless of which web broswer use.  I say certain websites, because it seems most of them DO work, it's just a few that don't (that used to).
So for instance, I'm trying to access and watch video from the Logo website -- specifically full episodes of "RuPaul's Drag Race."  When I navigate to and click on a specific episode to watch, instead of seeing the video appear (where it used to prior to this problem starting), I instead see a message that says:  "Video Requires the Lastest Flash Player."  Today I was at another website, and there were interactive parts of page I was looking at that just grayed-out and would not let me input info they were requestiong -- again in all thre browsers.  I suspect (?) a Flash-related issue.
Although I know my way around a computer, I am not a techie, and don't know what to do to troubleshoot this level of problem.
Help! (please)

Hi Chris.  Thanks for the reply and help.
Yes, I do have several security things installed.  Lets see, they are:
- Trend Micro Titaniaum Maximum Security 2011
- Lavasoft AdAware Free Internet Utilities (with Ad-Watch Live) v 9.0.7
- Spybot Search & Destroy 1.6.2
- WinPatrol 2010 Plus v 19.x
I had also not too  long ago downloaded and installed some kind of ad/pop-up blocker for my  web browser called "AdBlock Plus v1.3.9 and accompanying Pop-up Addon  0.2.9 ."   I just uninstalled those to see if that made a difference.   It didn't.  All the other things I (still) have installed in list above,  I have had installed for years with no conflicts/problems.  I have tried turning off/disabling them all to see if that had an effect, and that didn't either.
One odd thing is that I have three computers at home.  The laptop (we've been discussing) as well as two other older Windows XP desktops.  All three computers have this very same problem, regardless of browser being used.
Here's the file you requested:

# This file contains the mappings of IP addresses to host names. Each

# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
