This problem is not just manifest on this site. This problem is something I have been running into right and left on the internet and wound up having to sign up for this site just so I could find out the answer on this forum as this seems to be the only place it is being discussed. I just hope that I did not open myself up to tons more useless SPAM from a site I may or may not ever visit again. I really hate having to sign up at a site just so I can see the answer in the forum just so I can really only just get more SPAM which is why I have the AntiVirus/Firewall in the first place.

Another Point

If you know what the extension of your file was supposed to be all you need to do is change the *.efw extension to the actual externsion it should have been in the first place e.g. change MYFILE.efw into MYFILE.exe or MYFILE.zip or whatever the real extension is supposed to be and the file WILL work. There is no real need to RE-download the file as you already have it. The only thing that is wrong is the .efw extension.

It is a problem with CA Anti virus they have been doing a lot of things that are really weird lately. In fact I have been turning things off in the program right  and left because they are blocking out a lot more than i care to have blocked out. One of the big things I have been noticeing is a message that says: <!-- Removed by HIPS FW----------------------> or something along these lines. This is the CA AV program doing this stuff. Most of it can be shut of by turning off the anti spyware part of the program AND shutting off (Uncheck everything in this section) the privacy section of the Firewall... Yes this will also get rid of the HIPS FW thing and will even make your web pages render correctly

CAV used to be my AV of choice but with all of the stupid stuff that they are automatically shutting off (or at least shutting out) I am now doing some research into other AV and firewall solutions... This however is very sad as i have been extolling the virtues of this product (CAV) and installing  it in client machines for over 12 years now while making the custmer get a subsciption to the service. Frankly it's either you get the CAV or you visit me and I charge you lots of money for fixing your computer and you still wind up buying the software it is that simple...

I'll leave this with the notify check box checked just in case someone has a pertinent question involving these issues with CAV.
