Installing and updating software is a common thing for everyone. It is recommended to update or install the software to improve the performance of your PC, however, in addition to the many beneficial features, installing and updating the software can pose many risks. In this document I will describe the potential risks of installing and updating .Virus software. A virus can be inside a file or an update; This virus can damage your computer system and corrupt files inside your PC. This is a potential risk because it leads to inefficiency in work, i.e. a file in which important information has been typed becomes corrupted and therefore becomes impossible to access, this leads to frustration and inefficiency in work as the document will have to be rewritten unless the individual does not have a backup.IncompatibilitiesIf your PC is older or you have other software installed, this increases the chances of a piece of software becoming advanced or conflicting with existing software. This may cause incompatibility between programs and prevent them from running. This is a problem because it takes time to resolve a situation like this; this type of situation will also prevent programs from running. Negative change/loss of functionality When software updates are released, they often contain added features and uses, this may cause problems as it may make existing features more difficult to use, these features may be such as changing shortcuts or the position of the task bar tools, this can reduce the efficiency of the level of work produced in an organization. Stability Issues When new software is installed or existing software is updated, the software may become more demanding on the system, this may affect the stability and performance of the PC: this may cause freezes, slowdowns and... half the paper ... the method is to check the functionality of the software during installation. If you check the functionality of the installed software during installation, you can then check the details and evaluate whether to install the software or not. Installing antivirus can also reduce the chance of exposure to risky software, antivirus on a system detects malicious files within the software being downloaded, an antivirus warns the user before downloading the file whether it is safe or less for updating the work. To minimize risks you could also perform the update or installation during your free time, this will avoid downtime, when the update and installation of the software on a PC should be carried out on days, for example, holidays, when there are no staff members using the system. A perfect example of this would be improving the school system during the summer holidays when it is not in use.
