Cannot be overstated. DO NOT DL from Cnet. You'll spend hours removing the junk they toss in.
Also, Ccleaner is a good cleanup product. In fact, everything I've tried from Piriform is good - recovered some inadvertently deleted photos from an SM card with Recuva, pretty good stuff.
Unfortunately, free gifts of toolbars, browser extensions, changes to your system and bloatware are the ‘new black’, and have been adopted by many software companies that have free versions of their products, as I have found last week, having to spend hours restoring my system after one careless download. Now IOBit Malware Fighter reminds me with every reboot that there is a new version and directs me to CNET (or download.com which is the same thing), and there is no way to download it pure. Oh yes, the ‘new version’ every week is another trick to tempt you to upgrade to a paid version, and to shower those free gifts on ya.
