Trojan Horse issue

[Pheebs]

Hey Guys and Girls

Not been on here in ages (only time I seem to go on internet is to load of spotify/brief check of Bookface! Am mega busy otherwise! Hoping you're all well I do check in every so often )

Having a problem with poota at the moment. SOmehow I've managed to acquire a trojan I think... it's put some "security" program "Security Tool" (unless this is a genuine program - not convinced it keeps asking for my card details - LIKELY!!!) on my computer which won't let me run any programs (avg included)/download anything and I can't get rid of it.

Not quite sure what to do :/

Any ideas... I'm clueless when it comes to things like this. Was wondering if there was an online scanner/trojan remover I could run?

Thank you BD peoples appreciative of any help!
