I need some desperate help. I had my brother in law go on my laptop that I just recently purchased and he went on some porn sites and apparently i have some crap hijacking my laptop. Eset can find it and i've tried to install numerous versions of Bitdefender but when I attempt to update Bitdefender i get " could not connect to the update server . Please check the internet connection and try again." But my internet connection is fine. What do I do? How can I get all of this crap out of my system? What application can I use?
