I keep getting a warning strip coming up on my XP operated laptop screen thus
"Either there is no default mail client or the current mail client cannot fullfill the messaging request. Please run Microsoft Office Outlook and set it as the default mail client"

Now
a) I don't have Outlook installed on this computer
b) I don't run any messenger type things on my computer so how did this message get there?
c) How do I stop the warning from coming up as it is very annoying, popping up every 15-20 minutes on the screen 2018 Mini Countryman Cooper S E All4 PHEV in Melting Silver - it’s whisper quiet in EV and polluter modes

Tim this can be caused by trojan variants presume you have a good anti V package on the laptop also download and run Malware-Anti_bytes
its free and will double check the background services Far to many gone...

I'm running the subscription version of Grisoft and also the paid up version of Registry Mechanic. Will have a go with your suggestion too TB, thanks 2018 Mini Countryman Cooper S E All4 PHEV in Melting Silver - it’s whisper quiet in EV and polluter modes
