I had that deep seated problem with a freebie Norton and finally resorted in stripping the lot out and reformatting the SSD and finally reloading windoze from a disc. . well TBH, my son-in-law did that for meš
Thatās the most thorough way.
I use āREVO UNINSTALLERā which clears everything out from the computer registery
I have found that it doesnāt.
depends on what setting you use, safe- moderate or advanced. which do you use?
I use advanced which works ok for me
Tried them all but still some left but I know experiences will always vary when it comes to computers. I think uninstallers remove all that is necessary so that the OS runs and doesnāt call on, or get upset by, old files and Registry entries. Just takes no notice of anything left and that is probably good enough.
I have personally found that RegScanner and āEverythingā will still find leftovers. Having said that, it can be dangerous to try and remove every single reference to an uninstalled security program. I once did that and the OS ran strangely afterwards. Ended up having to do a repair upgrade. A good way of putting right any user mess-ups without losing anything.
