I am facing a strange problem.The problem is that I bought a pen drive from my fren and plugged it into my PC.In his pen drive there is a folder named new folder which cannot be deleted but I double clicked it on it.And I think the folder contained virus and has infected my PC.Now in the tools tab there is no folder option and I cannot see my hidden file.Next I cannot open up task manager when I try to open it it says task manager has been disabled by your administrator.So what has gone wrong here.Can you figure it out and help me pls?
