While it is sometimes easy to notice that something is not all right with your PC, for instance if it is slowing down after minutes of use or crashing regularly, it is also possible that you are oblivious of issues, for instance if they do not have direct impacts on your day to day activities.
Examples of this may be running old software versions, security patches that have not been installed yet on the system, or running the system without firewall.
Webroot System Analyzer is a free product for Windows that you can use to identify potential PC issues. The program has been designed primarily for businesses, but it can also be downloaded by home users.
Note that you do need to fill out a form on the Webroot website before the download link becomes available. You can download it directly on third party software portals such as Softpedia.
The program scans the PC in a couple of minutes and displays its findings afterwards in a summary report on the screen. Items are rated with red and yellow items requiring your attention the most.
The program rates your system and displays individual ratings for the Hardware, Software and Threat groups.
Each issue is listed with a single sentence here that may or may not provide you with enough information to resolve it. You can click on the view advanced detail link here, but it too lacks information. In fact, it does not list additional details at all, but adds a couple of new results to the list that have not been listed on the application's front page.
That does not necessarily mean that the program itself is useless, only that you have to find other ways to dig deeper into the reported issues.
Note: If you are running Firefox, you will notice that the program will list it as a process with a possible memory leak. While I'm not 100% certain how it comes to that conclusion, it may very well be the case that it only looks at processes that consume more than a certain amount of memory.
You can click on view full report on the advanced detail page to open a text document containing all data that the program has accumulated during the scan.
Webroot System Analyzer is a free program that scans your PC for potential issues. While it will hint at issues it has identified, it won't provide you with any means or explanations in regards to resolving those issues on the system. While some are easy enough to fix, like the "large number of temporary files" warning, others like the identification of possible memory leaks may require extensive research on your part.
