In a digital computing environment, a method of protecting stored and transmitted computer original files from unauthorized access, by encoding a series of physically allowed restore locations into a plurality of site-specific protected site data files, and rearranging the internal structure of the original file's byte data into a specified non-linear sequence, and storing them into the plurality of site-specific protected site data files. The protected site data files can then be individually stored across two or more physical and/or online storage sites to implement an effective form of file security. A user selects the original files they want to protect, a plurality of physical allowed restore locations, and a plurality of storage sites they wish to use to protect their original files. Each original file is processed at the bitwise level, with each successive bit from each successive byte being appended to the next successive protected site data file. When the last site data file is reached, the process continues back at the first site data file. The resulting output is a series of protected site data files which, when physically separated cannot be accessed by an attacker without having collected all other protected site data files available. In the event that the attacker is somehow able to collect all of the protected site data files, they are still restricted from restoring them, unless they are physically present at one of the previously designated allowed restore locations.

System and method for protecting information from unauthorized access

A malware detection system capable of detecting and removing malware from a computer system. The malware detection system determines whether there are files potentially related to a selected malware file using a time-based embodiment based on whether files were installed around the time of the malware. A cache-based embodiment searches an Internet cache to determine the URLs that might be the source of the malware. A location-based embodiment dissects the file system path to determine an application related to the malware. Results are displayed to the user for action.

Determining the source of malware

In a digital computing environment, an improvement to a method of scanning for and removing spyware, includes periodically detecting a current usage level of CPU and disk resources to generate a current usage level signal. In response to the current usage level signal, a rate of scanning for and removing spyware is modulated, based on CPU and disk resource usage from a first time period to a second time period. The scanning for and removing spyware does not substantially interfere with a user's employment of the digital computing environment.
