AdvancedSetup told me that I should post here. First off, my PC was like any other PC. About 2 or 3 weeks ago, the MS Automatic Updates program had downloaded some updates. Since then, my C drive always has below 100MB free space. Whenever I try to delete something, a Microsoft error windows comes and I have to click 'Send' or 'Don't send', then everything disappears including the taskbar, then everything comes back up after 10 seconds, but everything that was open, closes. The exact same thing happens when I right-click on any file or folder. So I wanted to free up some space so I could use System Restore, so I went into Control Panel->Add or remove programs to try and uninstall programs with hefty memory. There should be a 'Remove' or 'Change/Remove' button under each program installed, but that isn't the case for me. I can see no buttons whatsoever. I've installed Anti-Malwarebytes, and had a total of 8 infected files, and deleted them. I've also tried many other programs to get rid of harmful software, even registry cleaners. Nothing seemed to do the job. That's about it. Any form of help is much appreciated. TIA.
