MacClean promises to improve security and privacy as well as clean your Mac

iMobie has released MacClean 3.0.5, a brand new version of its freeware Mac cleanup tool. The app, which boasts a large number of cleaning tools, returns with a new security bolt-on and completely redesigned user interface.

Version 3.0.5’s major new feature is the implementation of new privacy and security tools, the latter based around the open-source ClamAV malware scanning engine.

The new security tool requires a separate download and installation -- it’s packaged as 'Security Engine and Database', but is actually the open-source ClamAV tool, which is used to scan for threats on demand. Any detected threats then find themselves placed in the program’s new Quarantine section for further review and action – if required.

MacClean 3 also unveils a new Privacy Issue scan, which allows users to review recent app usage, opened documents and even 'private' app histories. Once done, users are invited to review what’s been found before cleaning.

A third tool -- Malicious Cookies -- scours the caches of popular browsers (including Safari, Firefox, Chrome and Opera) for cookies known to steal personal data and compromise security in other ways.

The app also unveils a complete redesign, showcasing a more minimalist user interface that sits in nicely with the latest OS X look and feel. The app also reorganizes its tools into two sections, with the scanning tools listed under Cleanup and other tools found under Utilities.

These additional tools -- some of which are used by the program’s scanning components -- are split into two sections: Cleanup Tools include a duplicates finder and 'old and large files' tool for rooting out potentially redundant space hoggers. There’s also a secure file eraser and tools for thoroughly cleaning apps and getting rid of unused language files.

Optimization Tools features an iPhoto cleaner, extension manager, secure trash sweep and 'binary' junk remover that attempts to streamline individual app sizes by removing what it terms 'redundant binary junk'.

MacClean 3.0.5 is available now as a freeware download for Macs running OS X 10.7 (Lion) or later.
