The Cleaner 2012 is free on 4/4/2011 at Giveaway of the day. The Cleaner (TC) classes itself as being an anti-malware app, so I am posting TC's freebie-notice in this thread. I imaged my system drive then installed TC without incident. TC didn't require a restart during install so I *assume* it could be installed/tested via Shadow Defender et alia. It was medium-light running in real-time. Updates are smooth, fast, thorough. GUI is utilitarian & easy to understand. Inasmuch as I do not need another real-time security app, I changed TC to on-demand. Using Autoruns, the change to on-demand was VERY easy. I rebooted TC to check it. TC did not put ANY process into real-time & made no fuss whatsoever about being relegated to on-demand status. After the reboot, I tested TC's on-demand status by doing an update & by doing a right-click scan of a file. TC did both jobs without complaint & remained in on-demand status. TC has been around for many years & used to be *somewhat* respected at Wilders in days of yore. Then it fell from favor. If a competent tester checks out TC's effectiveness, I would be interested to see how it does as of now.
