How can you permanently delete tracking cookies' virus?

Tracking cookies are not actually a virus. Some antivirus software detects them, because many users do not want them. Tracking cookies are used by advertisers to detect when you view their advertisements. If you do not want tracking cookies, you can visit these advertisers' websites, where they generally provide you with the option to opt out of these cookies.

Install CCleaner from piriform and that should remove all the cookies on your Windows system.
