Of course 50kB file doesn’t matter, but i in display preferences is broken screensaver that is why i removed it. So i learned one thing now, never let avast update to new program version. One thing what is bad, it comes with new uninstaller, so if i will want in future remove it, it doesn’t delelete files from previous versions. And second thing is i cannot choose what modules i want install. It install all new features automaticaly. Personally i don’t trust avast safe mode unistaller called “avastclear”. It is just universal uninstaller for all versions which not come with my product so is not able delete files that good as standart uninstaller from control panel. Is good use if standart uninstaller not work of course. So for example, one day avast decide remove safezone browser from this product, you let update avast from gui and if you uninstall it safezone browser stay uninstalled. There will be no way uninstall it. Try think about it.
