You can try, but you won't be successful. Most software is not designed to intentionally "harm" your computer, so any damage is unintended and not their responsibility. Software companies warn you of this when you install their software. The following was culled from Microsoft's EULA (End-User License Agreement): "Microsoft and its suppliers provide the Software and support services (if any) AS IS AND WITH ALL FAULTS, and hereby disclaim all other warranties and conditions" "IN NO EVENT SHALL MICROSOFT OR ITS SUPPLIERS BE LIABLE FOR ANY SPECIAL, INCIDENTAL, PUNITIVE, INDIRECT, OR CONSEQUENTIAL DAMAGES WHATSOEVER (INCLUDING, BUT NOT LIMITED TO, DAMAGES FOR LOSS OF PROFITS OR CONFIDENTIAL OR OTHER INFORMATION, FOR BUSINESS INTERRUPTION, FOR PERSONAL INJURY, FOR LOSS OF PRIVACY, FOR FAILURE TO MEET ANY DUTY INCLUDING OF GOOD FAITH OR OF REASONABLE CARE, FOR NEGLIGENCE, AND FOR ANY OTHER PECUNIARY OR OTHER LOSS WHATSOEVER) ARISING OUT OF OR IN ANY WAY RELATED TO THE USE OF OR INABILITY TO USE THE SOFTWARE" The emphasis is theirs. This is a typical declaration, which you agree to when you install the software on your computer. It's inside one of those boxes you automatically click "yes" to, but don't bother reading. Software comes with no real guarantee, apart from a statement that it should work as designed and, if it does not, the manufacturer may refund the purchase price after due deliberation. This is all you get in this day and age. In the era of mainframes and minicomputers, software manufacturers did provide real guarantees that their products would work. They also charged a whole lot more for their software than we pay for consumer software today. ------------------------------------------------------------ Re: "Ask Sony/BMG" Yes, but their XCP anti-piracy software was installed without the user's consent - a substantial difference. They claimed the product did not do what it did and presented no risk to a consumer's system, which was false. They mislead consumers by providing several software removal tools that they claimed would remove the software, but did not. They forced consumers to fill in application forms to obtain clean CDs and provide personal information unrelated to the issue, instead of recalling the affected media from stores. Then they were outed on another anti-piracy product, MediaMax, which they handled almost as badly. There is a world of legal difference between a company stating that they accept no responsibility for your installing a product that may harm your system, such as blowing away a critical DLL with an outdated version(kudos to Kodak for that one), and a company that claims they never installed anything on your computer, when they did, and then set out to intentionally deceive you. The end result was a class-action lawsuit, with broad support from many parties, not a suit brought by an individual. Historically, these have been unsuccessful.
