Windows XP SP3 (Yes, I know ...) and Firefox
Just removed my old security software and installed Kasperski 2015 Internet Security. Surprisingly slow, and aborted a full scan after 5 hours and 30% coverage. One of my remaining irritations is that 5 addons have been installed by Kasperski. One of them, 'URL Advisor' is labelled '.. incompatible with Firefox 39.0'. All 5 are listed with buttons to disable - but after disabling and restarting Firefox all 5 of them are back. There seems no way of removing them from Firefox.
I've searched the internet and tried all the suggested methods but without success. It seem that Kasperski has decided that I will have them installed, whatever my preferences may be. Can anyone assist here?
