What is Diranalyze Disk? And how does it work?

Diranalyze Disk is a disk optimizer that scans a drive for any duplicate files or junk files and shows how much space does the particular folders are using in your hard drive storage. If installed, several scheduled tasks will be configured to launch programs that connect to remote sites and that right there is a dangerous behavior and is one of the reasons why this program is classified as a potentially unwanted program (PUP). As you can see on the illustration above, Diranalyze Disk may look like a legitimate program, however, it’s not as harmless as it may seem.
After a series of tests, our researchers have found out that Diranalyze Disk does not perform any optimization operations but it allows you to load a chart with data available on the disk. It also drops several files within several directories on your computer, making its removal difficult. The files that this tool creates are all suspicious. Thus its removal is a must and you shouldn’t waste your time and let it linger any longer in your computer.
How is Diranalyze Disk distributed?
This suspicious program does not have any official distribution sites and so it is not brainer where this program can actually be obtained. As far as our research team is concerned, this unwanted program is actually distributed through software bundles which are found on free sharing sites. to avoid such unwanted programs, it is best to avoid downloading software bundles and opt to download programs from their official download site.
