Oh good you went with the trial, good move. I definetly recommend that instead of blindly buying Bitdefender since its reported to have a lot of bugs by users.. Be careful of higher tier "protections" that a lot of antivirus companies offer since most of the extra features are usually borderline useless, only go for the higher tier upgrade if the price difference is small or if there a feature that you need.
I look at Bitdefender product comparison, here are the breakdown so you understand what extra stuff you are getting on each tier.

Internet Security Extras:
Two-Way Firewall - This might be an upgrade on monitoring over the already awesome default window firewall but there is a security hole that will make you prefer windows instead. . AV-Comparatives did a report on their test on anti-virus firewall and found that window default firewall actually was more secure than most anti-virus firewalls. Bitdefender was one of them that had a security hole when using wifi I believe. Its a very minor though that require hacking skill to get remote control of your laptop in a public place. Makes sense when Microsoft made their OS windows so they know how to make their window firewall work well and doesn't require intense continuous research to keep it updated like an antivirus. It is design for casual users so it won't have the extra controls like traffic monitoring as Bitdefender likely does so that a plus for getting an antivirus firewall over windows.

Enhanced! Parental Control: Either you plan to use it or it's totally useless.
Enhanced! Cloud Antispam: This is most likely useless. Bitdefender Antispam protection is available only for e-mail clients configured to receive e-mail messages via the POP3 protocol. This means the following:
- E-mail messages received via web-based e-mail services (such as Yahoo, Gmail, Hotmail or other) are not filtered for spam by Bitdefender.

Total Security Extras:
Secure Online Storage. Bitdefender Safebox™: Useless, just use Google, Microsoft, Apple, or any other freebies cloud service if you need it to upload files to then download it on any other computer.
Device Anti-Theft: I guess this is for laptop (can't tell if mobile count as PC for this product). This is something but I hope you already took all measure to not lose your laptop/mobile in the first place.
File Encryption: This can be useful. You use this to lock your sensitive files like passwords and stuff on your computer that will then require a password to open it. If your computer is compromise this will prevent your important files to been seen.
