Do others use your computer or laptop at home or in the office? If so you are probably worried about them installing questionable programs in Windows when you are not around. Here’s how you can prevent software from being installed in Windows.

In Windows 7 or Vista, from the Start menu type gpedit.msc in the search box.

In Windows 8, swipe the right side of the screen, click the search icon, and type gpedit.msc

This will open the group policy editor.

Go to Computer Configurations > Administrative templates > Windows Components > Windows Installer. In the right pane double-click on Disable windows installer

Make sure Enable is selected

Selecting Always disables the Windows installer.

The default setting is Never. This allows users to install and upgrade software.

Selecting For non-managed apps only permits users to install only programs that a system administrator assigns.

Please note that this only affects Windows Installer. It doesn’t prevent users from using other methods to install or upgrade programs. Also, when you are ready to install an application you will need to change this setting back manually.

How To Fix: Browser stuck on a New Tab

Apr 2014

Typical Chrome New Tab page

If your browser cannot leave a new tab page such as the Chrome one shown above and cannot navigate to another web page, here are a few possible remedies.

First, check if the keyboard or mouse is the issue.

Check if the backspace or other key is stuck. If that is the case, try to raise the key. Failing that, unplug the mouse and keyboard and see if the problem persists. Perhaps a key or short cut is being repeatedly triggered without the user’s knowledge. This can be confirmed by using a different keyboard or mouse.

Second, if it’s an issue with the browser

Other than Internet Explorer, you should save bookmarks into an html file then uninstall the browser thoroughly with an uninstaller tool such as Revo or from the Windows Control Panel. Reinstall the browser and see if the browser still freezes on the new tab page.

Internet Explorer is integrated with the Windows installation and cannot be simply uninstalled. For IE, after backing up desired new settings, configurations, and files, perform a system restore. Restore Windows to the last remembered time that the browser did not experience the new tab persistence problem.

Major Online Security Bug Found: Heartbleed

Internet, Securityheartbleed, network, openssl, securityOphtek, LLC

Apr 2014

A major OpenSSL bug has been found that could affect 70% of secure websites.

A major bug has been found in the popular OpenSSL library used by thousands of online merchants, email providers and banks. The bug allows anyone on the internet to read a user’s private information while it is being sent back and forth to the website. A security advisory has been issued by OpenSSL.

Why is the bug called Heartbleed?

The code affected by this bug is in the heartbeat portion of the protocol which keeps the connection to the website active. When the bug is exploited it causes memory to leak its content while it is being sent over the internet, which contains sensitive and private information.

How does this affect me?

If the website you are logging in to, such as your bank, email or an online store uses a version of OpenSSL that has this bug:

An attacker can open a connection to your bank over and silently download among other things the keys used to prove the bank is who they say they are.
They can then pretend to be your bank and you will not notice anything different, while all of your communication is being stolen.

It is estimated that up to 70% of internet websites are affected by this bug. Companies can fix the bug by upgrading to the latest version of OpenSSL, creating new certificates and removing old certificates.

How can I protect myself?

First check if the website you are accessing has an “https” in front of the address, meaning it should be a secure connection. All banks, email webpages and online stores should have this:

If it is a secure connection, enter the website here to check if the bug exists.

http://filippo.io/Heartbleed/ will let you know if the site has the Heartbleed Bug.

If it does exist, avoid using the website until they have upgraded their OpenSSL. For further assistance with the Heartbleed bug or other security issues, contact your local IT professionals.
