Solution UPDATE: 

It seems that Browser SafeGuard has evolved, we have now seen that it has renamed itself to RocketTab.

To uninstall, please go to Start -> Control Panel -> Programs and Features (may be labeled Programs or Add / Remove Programs) and locate RocketTab.  Right click on it and select to Remove or Uninstall.

Solution:
Please uninstall a piece of software called Browser Safeguard.  It can be identified in the notification area (by the clock in Windows) by its icon which looks like a gray shield.  Right-clicking and exiting Browser Safeguard will allow your applications to launch, however it will need to be uninstalled to prevent it from launching again the next time Windows is restarted.

To uninstall, please go to Start -> Control Panel -> Programs and Features (may be labeled Programs or Add / Remove Programs) and locate Browser Safeguard.  Right click on it and select to Remove or Uninstall.

If you do not see Browser Safeguard in the Windows notification area, or if you do but it doesn't show up in Programs and Features, please contact our support team and we can help you get the problem resolved.

In some cases Browser SafeGuard will not show up in programs and features. The best way to ensure that no files are left on the computer, download Revo Uninstaller Pro Trial from www.revouninstaller.com 

Once downloaded, follow these steps to completely remove Browser SafeGuard:

7 – select the “Forced Uninstall” tab on top.

7a – Select the “advanced” option

7b – under “Program’s exact name”, enter “Browser SafeGuard” and select “next”

7c – If any apps are found, re-select “advanced” on top, highlight the app and select “next”

7d – Next a screen will appear saying “Performing the initial analysis and uninstall” – Select “scan”

7e – next a screen will appear saying “Found leftover registry items”. Click “Select All” and click “Delete”. Select “yes” to confirm. (If it says it cant delete the files selected, you can search for the open processes or use unlocker 1.91 to kill the process and delete the files. This is a very useful tool. If you use this, I recommend making a donation. (http://www.emptyloop.com/unlocker/)

8 - Keep repeating step 7 until nothing more is found. This process will need to be ran on the admin and user profile.

8a – Next a screen will appear stating “Found leftover Registry items”

8b – click “Select All” and click “Delete”. Select “yes” to confirm

8c – Next a screen will appear saying “Found leftover files and folders”. Click “Select all”, click “delete”. Select “yes” to confirm.
