I simply used Windows Search for all existing instances of Vosteran, including the Registry Editor and removed them manually. Took me about 10 mins and I no longer have any problems with it. Larry
Malwarebytes Free is effective against Vosteran and many similar PUPs.
I did not install Vosteran and some how it got past you, this happened on the 19/20 and I did not install any new programs other than Spotify. One Spotify installed from a third party vendor had multipal software scams and I cancelled the install but somehow I got it. Waht can i do to get rid of it?
