Windows 7: Disabling System Protection

Sometimes there's a need to turn off the System Restore feature (e.g. such as recovering free space on a drive).  By disabling the System Restore functionality, note it will be permanently deleting all existing restore points from the drive.

Below are the instructions on how to perform this action:

  • From the Start menu, select Control Panel
  • Select System and Security, and open the System control panel
  • In the left pane, click System Protection
    • If the UAC is enabled, the administrator credentials will be required.
  • Select the drive to disable the System Protection feature.
    • Generally feature is enabled on Windows system drive, which in most cases is the C: drive.
  • Press the Configure... button, when the System Protection dialog displays, select the Turn off system protection radio button, then press the OK button.
  • Press the OK button again to close the last dialog.

Mikko Hypponen: Fighting viruses, defending the net

This video is a great introduction to modern day malware (e.g. viruses, worms, Trojan horses, etc.).

It's been 25 years since the first PC virus (Brain A) hit the net, and what was once an annoyance has become a sophisticated tool for crime and espionage. Computer security expert Mikko Hyppönen tells us how we can stop these new viruses from threatening the internet as we know it.

If you want to know more about how to protect yourself and your family on the Internet from fraud, scams, and malware, check out my book "Avoiding Information Insecurity: Fighting Modern Day Cyber-Threats (2011 Edition)" (ISBN 978-1-4580-2920-1) [For my blog readers I am offering a limited time [October 14, 2011] special deal of 75% off the cover price of the book, use the coupon code TL78X at checkout].

The Rasterbator - Make a Poster from any Image

The Rasterbator allows you to creates large posters (up to 20 meters [or 65 feet] in size) from just about any image. All you have to do is upload a picture (from your computer or from a URL), print the resulting multi-page PDF file and assemble the pages into a poster.

The Rasterbate service is available in two versions, online (which requires that you have Adobe Flash Player 7 and PDF viewer) and an off-line downloadable executable. Its pretty easy to use, after you have cropped the image and selected a size, the "rasterbated" image will be sent to you as a PDF file.

HTTPS Everywhere Firefox extension

I am a big believer in all types of encryption, to protect yourself and your data while utilizing the Internet you need to encrypt everything.

Many sites on the web offer encryption over HTTPS, but default to unencrypted HTTP communication when you visit their site. HTTPS Everywhere is a Firefox extension from the Electronic Frontier Foundation that forces encrypted  communications with a number of major websites (if this option is available). The HTTPS Everywhere extension works by trying to rewrite all requests on a site to utilize HTTPS.
Note: if the site your visiting is not enable in the extension or site doesn't support HTTPS this browser extension will not work.
