Hello,
I have noticed that sometimes my settings in my antivirus change on me and Paranoid mode never stays on for me =/. Does this means that my laptop is infected? Also I tried the password protection setting but that does absolutley nothing, all I have to do is hit cancel when the pop up comes up to enter my password and the settings change anyway... 
Also I have noticed in my events Bidfender detections alot of cookies as viruses. What show I do with these when the are detected? Should I delete them restore them or just leave them alone? I have been deleting them for fear that they will harm my computer but I looking for advice!
Thank you!
