.SYS Files

.SYS files are otherwise known as System files. These files serve as configuration files which are key components of your PC or laptop's operating system. In basic terms - it is the .SYS files that enable your computer to function.

The system registry is undeniably one of the most vital parts of any Window-based computer system. It is this Windows Registry that hosts the majority of the .SYS files and it acts as a "atalogue" that tracks every piece of application and hardware specification, their configurations and how each one is intended to interact with other operating system components.

Commonly, system files cause system registry problems due to invalid or missing keys and may cause system stalls, slower operation or even crashes. These can be attributed to frequent installation and removal of applications and hardware. Frequent changes affect the health of the system registry and in the long run, can cause problems with the stability and efficiency of the system.

A registry cleaner and optimizer can protect your Windows registry by regularly scanning the registry for invalid and missing keys and correcting problems that tend to slow down computer operation. This type of utility will also help prevent system crashes and maintain the health of your system.

Driver Conflict

Another problem attributed to .SYS files is freezing of the system due to conflicting and faulty or unsupported device drivers that cause over use of operating system resources (i.e. RAM). This eventually causes the system to freeze and you will get the "blue screen" and your computer will crash.

The Device Manager can help troubleshoot problems related with hardware/driver conflicts because it usually flags problematic hardware with a black exclamation point embedded within a yellow triangle. Installing registry optimizer and an automatic driver updating utility (such as DriverCure) will solve your driver conflict issues and keep your .SYS files operating as they should.

Other factors can cause system freezing, like overheating components or hardware malfunction (not related to the device driver installed in your system). Preventive maintenance is the key to resolving freeze up issues, through installing compatible drivers, keeping the hard drive free from errors by regularly conducting a defragmentation and regularly updating with the newest security patches and releases.

Regularly updating and running anti-virus and anti-spyware utilities will go a long way in keeping your computer free of malicious code, together with the use of a trustworthy registry cleaner that can perform regular registry scans and repair (if needed) in order to keep the system healthy, speedy and error free. Having anti-spam, privacy controls and a reputable data recovery utilities are a must and will keep your PC or laptop running error free.

The File System Fork

The Fork is additional information that is associated with a file system and which has an arbitrary size that can be bigger than the file’s data. Traditionally related to Apple’s Hierarchical File System, it is the counterpart of the Alternate Data Streams in Microsoft’s NTFS file system. In the Apple Macintosh, files were allowed to have a resource fork that would store metadata for the Graphical User Interface of the system and other services. Microsoft’s NTFS file system had pre-existing operating system support for forks and was later on utilized to store title file attributes including thumbnails.

Forks however come with an associated risk of data loss or a potential security threat. The user is only aware of the main data fork and never of the existence of an alternate fork that a computer virus can use to hide itself in. This makes it almost undetectable by anti-virus applications that are not aware of the forks. Loss of data happens when there is a transfer of data to systems or even using software compression methods that do not provide fork support.

It is clear that it is not enough to have just any anti-virus application but an anti-virus application that can completely and competently seek out all possible sources of infection in order to produce total security for system files and data.

Minimizing Security Threats

Before opening one of these file extensions ensure you have good anti-virus, anti-spyware, spam controls, privacy software, a registry cleaner and trusted data recovery tools activated and protecting your system.

To understand the impact of malware on system files, it in necessary to know that they need to be executed first before they become resident in the memory. The technique involves the execution in every system session by linking itself to locations of system initialization or operating system pre-configuration, hence the vulnerability of system and configuration files. To address this problem, an anti-virus program may not be enough since a malware program is different from a virus code. Thus, an anti-malware tool is necessary to effectively resolve this problem. If you have all the right tools, you can address all potential threats to your system.
