Thanks for the quick reply. Maybe nasty was too strong a word, lol, but nevertheless, a few examples. When i run a performance check, it says, for example, microsoft one drive is a major "slow my pc down prog", and yet, i don't even have that awful prog installed on any of my ssd or hdds. I also have the same kind of message for powerdvd 11, which was on my pc briefly over 2 years ago, but is no longer anywhere near my pc or in any registry files. Also, it even states powerdvd is in my registry, under the hkey_local machine, and yet, when manually and program searched, nothing to do with powerdvd is found, not even a blank entry. This is why i could not trust to use premium and delete what avast recommends me to, i mean, would it damage my pc and screw up existing progs or not do anything since most things it says it "detects" don't actually exist ? Could this be a bug ? With this doubt, i would be inclined to just keep the so called "broken registry" items and "slow performance progs" to which, it thinks that a prog running at 0.2mb is a resource hog ?!
I've never really trusted any program to tell me what needs to be deleted from a pc, i rather more trust the pc user experience and tech forums for advice and reading, instead of taking things at face value, especially progs that are designed to always, and i mean ALWAYS, persuade users to upgrade and use premium services. I like Avast, and because i have integrity, and the fact i may use out of date software, i could easily use Avast premium for free through the plethora of ways one can nowadays, but i'd rather use the free option and pay if i knew what i was getting was above standard and trustworthy, but that's not going to happen with today's saturated market !
