I purchased GrimeFighter yesterday. It would not ever run on my computer. I too would get to the locked point where it was Sedating My System....and froze right before the end and then "reported to headquarters" or whatever message that is.
I came on here and read some pretty disturbing things on the thread.
I followed your advice and uninstalled Avast! (using the Avast clear) software) and went back and downloaded and installed the latest version of 2015 Free! using the link on these threads. No difficulties with the installation.
NOW, though, I do not see any way to access GrimeFighter whatsoever. On my Scan screen, there is no "Scan for performance issues." It is not listed under "Tools" or "Store." When I go online I have a valid Grimefighter license.
Any advice? I would call technical support but the feedback on here is they aren't very helpful & I usually prefer to do simple things myself. Should I submit a ticket? Ask for a refund? I am not happy with the product thus far at all..
