The last couple of times when I have turned on the computer after about a minute Bitdefender shows an upgrade ad. This is irresponsible. I have no problem with Bitdefender sending me the occasional email with information on new products or upgrade notices but to have ads show up on a desktop is out of line. These must be stopped immediately.
I choose to allow a virus checker program to run all the time. This does not mean the virus checking program can distract me and stop my work flow by placing a pop-up ad on my desktop.
