Synei PC Cleaner is fast and easy-to-use piece of software that intelligently removes unnecessary files from your computer, in order to recover some free space and eliminate Internet activity to preserve your anonymity when sharing the PC with other people.

The setup operation takes little time to finish. The app is packed in a clean interface with a very intuitive structure, where you can get started by selecting the PC areas to clean.

When it comes to web browsers, Synei PC Cleaner handles data found in Internet Explorer, Google Chrome and Mozilla Firefox, such as cookies, downloaded files, history, bookmark icons, app and asset cache, and passwords.

It also deals with data from common applications, like Apple products (e.g. iTunes cache), Microsoft Silverlight, Sun Java cache, and Adobe Acrobat. As far as the system is concerned, Synei PC Cleaner deletes content from the Recycle Bin, MRU list, Microsoft Office cache, recent files, Windows cache, and so on. Advanced cleaning options include .NET Framework temporary data, Adobe Updater logs, cached file extensions, Chrome backup, and many others.

Scanning results show total size and files found in each area and overall. Double-clicking an entry brings up more an extended information panel which contains the exact path and size for each file. This information can be exported to a plain text document for further analysis. It is not possible to select the types of items to delete after scanning, but only prior to it (all files are selected for removal).

In addition, Synei PC Cleaner provides a decent disk cleanup function that focuses on Active setup temporary folders, memory dump and Internet cache files, temporary setup and Windows upgrade log files, and others. These sections can be customized for scanning as well.

There is also a toolbox included, which contains a deep cleaner for broken shortcuts, zero-sized files and empty folders, letting the user choose the exact file types to take into account (e.g. TMP, OLD, DMP, LOG). It is also possible to disable computer hibernation. Program activity is recorded to a logs section, and settings can be saved for later cleaning jobs.

Regarding program settings, Synei PC Cleaner is capable to automatically save selected locations, securely delete data using up to 7 passes and with/without applying force, skip recording scan history, run in advanced mode by default, as well as to create a system restore point. These options can be restored to their factory parameters.

CPU and RAM consumption is low, while scan and clean jobs are carried out quickly. We have not encountered any problems during evaluation. For a free application, Synei PC Cleaner does a pretty good job at cleaning data, backed by advanced customization options and other useful functions. There's also a portable edition available.
