I got a question on my post about how to fix the Removed by HIPS FW bug and I thought it was worth answering in another post. Mark, who has Roadrunner as his ISP, had downloaded their free offer of CA Internet Security suite and had since noticed that many of the files he was trying to download (i think from e-mail) where getting changed to .efw files. This is CA’s way of making sure you don’t accidentally run a file on the off chance that it contains a virus. The real problem here is that it can often prohibit you from running files intentionally! There are two ways to handle this:

1. Rename the file extension - If it’s supposed to be a .zip file just rename it to .zip from .efw and you’re good to go! You will have to know what the file extension was supposed to be in the first place, but that’s all you have to do and it will work just like normal.
2. Disable the quarantine - If you trust yourself more than CA does then you can just disable the feature that renames the files, here’s how:

• Open the CA Security Center
• Click on CA Personal Firewall then Open Advance Settings
• On the Personal Firewall window, click the Email icon on the left
• Select the Email Attachments tab on the top right
• Scroll down and double click the .ZIP entry to pop up a small settings window
• Uncheck the Quarantine all matching files box and click OK
• Do the same for any other file types you regularly recieve

That should do it! Your version of CA could be a little different than the instructions provided above, but hopefully that will be enough information for you to find what you need, Good Luck!

P.S. If you just have CA for antivirus and are sick of it, then consider trying the free version of AVG. I have a link to the download site along with some other useful and free programs on my post about Great Free Software.  If you want a full internet security suite and are willing to pay for it, try one of the best: Kaspersky Internet Security 7.0
