Juzt-Reboot is an instant recovery software that protects systems from viruses, spyware, software issues, and other problems. It works by diverting any changes made to the system, such as from infections or software installations, to a temporary buffer zone. On restart, the buffer is cleared, restoring the system to its original state. This allows systems to be instantly recovered from a variety of issues without troubleshooting. The document provides examples of issues Juzt-Reboot can address and how it works to resolve them with a simple restart.

Pc maintenance security backup and troubleshootingTech Day Camp
Michael Hertz, from SoHo Systems, in Norwell, MA gives a talk about PC security, backup, trouble shooting and maintenance at Tech Day Camp Oct 22, 2011
The document discusses why computers slow down over time and provides tips to improve performance. It explains that unused RAM is filled with programs and spyware without the user's knowledge. It recommends installing at least 512MB of RAM for Windows and 1GB for Vista, and keeping 2GB of free space on the hard drive. Regularly updating Windows and antivirus software can prevent spyware and viruses from affecting the computer's speed.
The document provides troubleshooting tips for common PC problems related to hardware components like the power supply unit (PSU), motherboard, and BIOS. It discusses symptoms of PSU issues like no power, intermittent power, power but no display, and noise. Troubleshooting techniques emphasized are being methodical, eliminating potential causes one by one, and seeking assistance from online communities if problems persist.
This document provides tips for maintaining a healthy PC, including updating software like browsers regularly, performing disk maintenance through defragmentation and cleanup, backing up important data, using antivirus and firewall software to protect against malware and hackers, and basic cleaning of hardware components.

This document discusses several types of utility software and how they can impact system performance. It describes anti-virus software, backup software, disk cleaners, disk defragmenters, drive formatting, firewalls, and internet history software. It explains that utility software like anti-virus, backup, disk cleaner, and disk defragmenter programs can improve performance by removing malware, freeing up storage space, and organizing files efficiently on disks. However, it notes that utilities like internet histories may not improve performance and could reduce it by using storage space. Overall, the document concludes that while some utility software enhances performance, others may limit it depending on how they are used.
Anti-virus software protects systems from malware like viruses, worms, and spyware, and removes any existing malware to improve performance and prevent data loss. Backup software creates copies of data to allow restoration in case of system failure or data loss, improving security. Disk cleaners and defragmenters free up storage space by removing unnecessary files and organizing files, improving system performance. Formatting drives removes all existing data, allowing space for new data and potentially improved performance. Firewalls provide security without necessarily improving performance, while utilities like internet histories do not significantly change performance.

1. Malware refers to malicious software that can damage programs or systems. Viruses are a type of malware that can replicate itself and spread by modifying other programs.
2. Viruses can infect programs by modifying executable files, documents using macros, or boot sectors. They spread through file sharing and email attachments. Viruses have different phases like dormant, propagation, triggering, and action.
3. Antivirus software uses virus signatures and behavior detection to identify viruses. Infected files may be quarantined to prevent spreading while they are analyzed and removed or restored. More advanced viruses use encryption, polymorphism, and metamorphism to avoid signature detection.

This document discusses common computer errors, including hardware errors like blank monitors, hard drive failures, and faulty keyboards or mice. It also covers software errors such as access denied, file not found, and out of memory issues. Specific error types like disk read errors, boot failures, freezing, and the blue screen of death are explained in more detail. The document emphasizes the importance of properly diagnosing errors to identify whether the issue is hardware or software related.
The document provides information about booting of a computer system. It discusses that booting is required because the hardware does not know where the operating system resides or how to load it. A bootstrap loader, such as BIOS, is needed to locate the kernel and load it into memory.
The boot process begins with a reset event that loads instructions into the instruction register from a predefined memory location containing a jump to the bootstrap program stored in ROM. The bootstrap program then runs diagnostics, loads device drivers and initializes memory before locating and loading the operating system kernel to start the system startup process.
