Ccleaner is good software for cleaning system safely, have downloaded license copy for 1 year in July 20 as 50% discount price as offer was going on online, it cleans all unwanted files safely that’s what I believe, buying license for 1 year at Rs 275.00 approx is not a bad deal, by the time renewal date comes you prepare to buy a laptop so nothing much worry about cost of license copy, overall ok at this price.
