Hello.
I use a Blackberry Passport. I have set the internet setting for secured level (blocking pop windows, no cookies, anti-phising activated, webRTC deacvtivated). During net surfing, when a entered a tab in a specific site, a pop Windows appeared and announced the phone was infected with a number of viruses, 14 viruses (!!??). Actually, after, i checked that site from my PC and the antivirus program and firewall said the site was clean, no virus there. (i know, it was a Windows antivirus, but still....)
Also, the phone worked perfect, no problems after.
Because i had no important info in my phone, i made a backup with BlackberryLink Device setings and contact/calendar data. I have wiped my Blackberry. After a new install i restored the device setting and contact/calendar data.
Phone works perfect, of course, but i have a question (probably it sounds silly). Is it any change as a virus, malware, trojan, etc. (if there is one) to remains in the device setting or contacts/calendar data and to be restored all together with the backup file?? Or it can remains only in aplications or full backup option?
Thanks you for support.
