Baidu PC Faster scans your PC deeply to find and delete junk files, unnecessary programs, and large files that sap and compromise performance. It can scan and optimize all areas with a single click or individually. With an attractive app-like interface, it's easy to use, too. This free tool's extras include the FasterNow desktop widget, Game Faster accelerator, App Store download manager, and Wi-Fi Hotspot.
Pros
Deep clean: PC Faster's Deep Clean option looks for Privacy vulnerabilities ranging from video files to Office apps and cleans traces that other programs miss.
Large files cleaner: PC Faster found numerous large files that we could safely delete, including installers, extracted archives, data logs, and temporary files -- including its own temporary files!
Medalist: While our results didn't exactly support Baidu's claim that our PC was running 106 percent faster after cleaning, our machine earned a Bronze Medal for being faster than most other users' PCs.
Cons
Virus Scan: While the included Virus Scan (Cloud, Full, Custom, Internet, and Game Scans) tool is hardly a detriment, it's not an alternative to a full antivirus solution, and we worry some users might see it as such.
Use with care: PC Faster can delete files, remove programs, change settings, and do other things that can compromise your PC, so be careful what you tell it to do.
Bottom Line
Baidu's PC Faster cleaned and boosted our system significantly without causing any problems, even when pushed to extremes. It's one of the more complete and better performing system cleaners we've tried.
