I purchased Bitdefender Plus Antivirus, this is not supported to Windows XP. So used old software with new key.
If you istalled in your computer or laptop, can face many problems with any other software which is installed in your computer. Software can disabled, or any file missing because bitdefender delete the files as virus or trojan, and many times you can not install any software, because Bitdefender understand this is untrusted or virus.
Features and fuctions are useless. I can face problems in installation.
Never purchase Bitdefender, I have deleted this Antivirus from computer.
