If you update Flash while in the Internet Explorer browser, it wont work for the other browsers, you have to be in one of the other browsers to get Flash for them, You also have the choice to download Flash for whatever browser you want, usually IE is one download and all the other browsers is another download, since a buncha browsers wont let you choose run instead of save anymore, you have to download it and update from there

If you are attempting to browse to a particular URL (especially a site which doesn't ordinarily require Flash), but instead receive a Flash update pop-up with a download link, the red warning flags should be flying. Especially so when the Flash update version being pushed is out-of-date, and the pop-up is in a different language from normal for the site. The direct implication is that there is either malware involved, a DNS hijacking somewhere along the way, or a site that has been either hacked or is carrying malicious ads/scripts.
Malware on a system can show up in different ways, depending on what it is and what it's infected. If it has merely gotten into a browser, it can show up just in that one browser by hijacking a user's browsing attempt (even just occasionally) so as to make it look like a realistic error message, or it can totally redirect all browsing/searches to fake sites. If it has gotten beyond the browser, it can poison the local computer's DNS cache or the OS itself, so as to redirect all browsers to fake sites or do the usual malicious virus downloads. One must scan their system with a couple of anti-malware products to assure this is not a factor (at least using one's native anti-virus plus an ancillary product like Malwarebytes, etc).
DNS lookup site poisoning can afflict the particular DNS lookup site normally used by the computer, either at an ISP or out on the web, depending on what's normally being used. In such a case, trying another DNS service (plus flushing the local DNS cache) should get around the problem, assuming the poisoning has not spread widely to many DNS lookup sites.
As far as infected/hacked visited sites themselves, the problem will generally only recur for that particular site, and can usually be blocked by shutting off browser scripting and pop-ups. If those settings block a recurring problem at the given site, that's usually a good indication something is corrupted/hacked at the site.

In my case I couldn't access BBC radio catchup on my PC, my tablet nor a spare PC so I thought it might be something to do with DNS even though I don't really understand what DNS is. I performed a full boot scan plus a Malwarebytes scan anyway. How I could try another DNS service I haven't a clue so if anyone can explain (in laymen's terms) it would be much appreciated.

DNS = Domain Name System
DNS translates domain names (like *.opera.com or *.google.com) to the numerical IP addresses (like 64.233.160.0 - one of Google's addresses) that are actually used to address data packets over the Internet.
There exist Internet domain name servers that store the official records for which IP numerical address is associated with which domain name. These servers can be updated quickly when the records need to be changed by a legitimate domain holder (as they often are), but the servers can also be hacked or "poisoned", either directly or via corrupting the update process to cause a false IP number to be assigned to a legitimate domain name. That causes a query for that domain name to be routed to some other server IP associated with the hacker's malicious intentions.
Your computer also has a DNS storage section (its DNS cache) which maintains local correlation of a domain name and an IP number for recent or often-used domains. If the sought-after domain name is not in that cache, the computer will go out to a pre-defined DNS server to perform the search for the IP number. Some malware can attack the local DNS cache.
ISPs often maintain their own DNS servers for their clients, but a user can specify other DNS servers for his computer to use instead (OpenDNS, Google Public DNS, OpenNIC, etc). The DNS setting for Windows is accessed via the Control Panel's Network/Sharing Center; you will need the numerical IP addresses of the desired DNS service you wish to specify for the computer to use. If you do decide to change the current DNS server, be sure to write down all the existing IP numbers for the Network/Sharing DNS settings section and where they belong so that you can get back to them if you need to. A good outline of what is involved in setting a new DNS server can be found at:
http://www.howtogeek.com/167533/the-ultimate-guide-to-changing-your-dns-server/Some specific DNS sites that contain their own customized set-up instructions (and their IP numbers) are:
- OpenDNS http://www.opendns.com/home-internet-security/premium-dns/
- GoogleDNS https://developers.google.com/speed/public-dns/docs/using
- OpenNIC http://www.opennicproject.org/configure-your-dns/how-to-change-dns-servers-in-windows-7/
If you're not comfortable manipulating internal computer/OS settings, this is not necessarily something you may wish to attempt, though it is fairly straight forward if you're used to tweaking a computer.

Probably OpenDNS, though GoogleDNS is OK if you aren't uncomfortable with running all your DNS look-ups through Google's backyard.
