you have to inform any folks that may help you,,i have zoostorm desktop with an i7 cpu with 16 gig of ram with windows 10.
type and run regedit in the ' search pane ' windows vista win 7 and 8 or the search pane on the start menu in widows 10.
when regedit is open press f3 on te keyboard and type in sweet im .click on fin next and any nasty remains will be highlighted you then delete it rt click 'choose delete.
keep on pressing F3 and it will keep on searching ,until the ' finished searching the registry ' appears..
try that and post the results here...
you can choose to download a malware removal software which have a powerful uninstall eg Ccleaner, advanced system care , avg tune up, 2015..they all have free versions..
windows 10 has a fresh instal option and you may have to use that .you can also try restoring your system to a date before you encountered the problems with IM and other crapware be careful what ever you choose to do
