Hi Guys, just registered to add to this subject.
I am running Win7 Home Premium + SP1 and have had the same freezes for some time, which I thought was mem stick problems or power supply, both now discounted.
I have done 5 cleanups and re-install as mentioned and am still having these random freezes. I have just read through this topic and have now disabled BOTH web and ransomware protection. I will test with only one or the other disabled also, and will see what happens. I have attached the clean-up-results file for your info if it is any help.
Have used the Premium version for years now and only had the occasional problem but this is a real pain.
Thanks for reading.
