Akamai Technologies is a U.S. Internet Content Delivery Network (CDN) responsible for serving approximately 15-20 percent of all web traffic. Akamai operates a network of servers around the world and rents space to customers who want their web sites to work faster by distributing content from locations close to the user. A CDN receives data and places it on various legitimate servers all over the world. This allows the content (images, music, movies, etc) to load faster because it is delivered to the end user from the nearest server holding the content. Akamai has several CDN networks and akamai.net; akamaiedge.net; akamaihd.net are a few of them.
Also when accessing web sites like Facebook, Yahoo, Bing, Gmail and Twitter, a message may pop-up with an alert advising that a security issue was detected on "xxx.a.akamaihd.net" and ask that you confirm the certificate. If you attempt to connect to a web site over HTTPS, it will often reveal Akamai. See Akamai and SSL.
I have not been able to find one major anti-virus vendor which reports this issue as being related to malware infection. However, if you conduct a Google search, the results will show numerous sites reporting this as a virus. When searching for malware removal assistance on the Internet, it is not unusual to find numerous hits from untrustworthy and scam sites which mis-classify detections or provide misleading information. This is deliberately done more as a scam to entice folks into buying an advertised fix or removal tool. In some cases if the fix is a free download, users may be enticed to download a malicious file or be redirected to a malicious web site. I have personally contacted the Akamai Support Team for a more official explanation but they have not replied back.
In most cases, browser slowness, crashing or unresponsiveness when attempting to visit Facebook is an issue with Facebook itself, not an indication of malware infection. Permanently blocking anything related to akamaihd.net may result in not being able to view web pages correctly...therefore attempting to do that is not the solution.
Sometimes just clearing the cache and resetting your browser settings to default helps reslove the proglem.
If there is pop-up advertising showing "rvzr-a.akamaihd.net" in the address, the issue appears to be due to advertising that happens to redirect to a service which uses that particular Akamai domain for the ads or a "doggy browser extension/software" (PUP related to anything below) doing the same.

These are the most common solutions to eliminating the pop-up ads.
1. Go to Programs and Features (Add/Remove Programs) in Control Panel. From within Add/Remove Programs look for anything in the list above and select Remove.
2. Open your browser and disable (uncheck) all extensions. Make a list, then one by one, re-enable each extension to see if the pop-ups start appearing again with that particular extension. Once you identify the responsible extension...permanently remove it but let me know which one it was so I can update the above list.
3. The next step is to try clearing the cache and resetting your browser settings to default:
4. If the above did not resolve the problem, then create a new browser user profile.
