GG Thanks For Sharing
Yes interesting stuff. I use CCleaner with some antivirus software. I used to use CCleaner with AVG paid subscription but the paid for AVG with the surveillance was far too sensitive and after awhile it seemed like it showed false positives for Trojan horses that just could not be. I went to the forums and found AVG techs answering questions as if the infections were real but after following all of their advice, the Trojan horses did not go away.
Trend Micro missed many real infections that were slowing down my computer and Norton, although better at detection required too many updates and at times would just stop working without a manual update and then would allow malware in.
I now use CCleaner with Malwarebytes and IObit anti malware. I periodically use the IObit optimization software too to clean registries, defragment, run additional anti virus scans, etc... I am not advising you, just sharing my experience that works.
Of course I also periodically uninstall programs (since I use several java IDE's, visual studio, and statistical software) I do not need for long periods of time since even with plenty of hard drive space, my slower running laptop-- the processor slows down and my broadband bandwidth gets used up and I cannot watch Netflix or browse very fast.
For my high powered desktop there is no slowdown.
I agree it is difficult to tell false positives from real ones sometimes. I wll say that my IObit and Malwarebytes catch real infections that others have missed, even each other. Skype which I use frequently is a back door for malware and my Malwarebytes in particular blocks them. My IObit (both programs) help keep my computer running faster and smoother so I can watch my movies and apply my statistical software even on a low end processor based comp.
