Trial antivirus download ruined my laptop
                                                
                                                
                                                
                                                
                                            
                                                                                Hello, I found a trial antivirus download from avast and installed it on my laptop. Now my laptop only has white screen, I think it hang up after I had installed the antivirus software, the cursor of the mouse is not shown either. I decided to install a new antivirus as I think my existing antivirus which is Norton has expired. At least some functions of Norton has expired so I suspected my laptop‘s virus-infected.
