Well, noone wants to do the hectic process but it helps when we are troubleshooting the virus issue. As we need to download many security tools from internet inorder to fix the PC while the infections do not allow us to connect to internet via IE. Instead, keep popping up with annoying screens that we are infected and pay few dollars to get rid of infections which is totally a scam.
