Assuming hackers here are your run of the mill script kiddies and not nation states, hackers can:

Use Remote Exploits to access your computer (hacking your computer).
Trick you into running exploits on your computer (viruses, malware).
Trick you into disclosing the credentials to your computer or web services (phishing).
Manipulate company employees into handing over your login details or control of your account (social engineering)
Guess the credentials to your computer or web services (cracking).
Break into web services and determine your credentials (hacking web services).
While hackers will always know about security problems before everyone else, they are less likely to use their brand new exploits against random people. High value targets (whether they be financial (paypal?), political (fbi website?) or lulzy (the fappening)) are much more likely to be their focus. Unknown exploits are valuable: They are obtained by hard work or paying for them on the black market. But the moment you use them, everyone will find out and patch the hole. So the hacker wants to make it count, he doesn't want to blow his one shot on something worthless.

Day to day attacks will be from relatively unskilled hackers (script kiddies) and deployed against ip address on the internet.

Occasionally a large internet service will lose it's password database to hackers e.g. twitch.tv. Sooner or later one of these headline hacks will affect you.

In response you can:

Keep your operating system and software up to date to cut down on remote exploits.
Use anti-virus and anti-malware scanning software.
Be wary about running unknown software or logging into untrusted sites (common sense 2016).
Run a restrictive firewall to allow only certain applications access to the network.
Use a password manager to generate random, secure passwords for your local computer accounts and web services.
Use a different password on each site. Knowing one password shouldn't make it easier to guess the others.
Give fake personal info where possible, so that info from one hacked account can't be used to break into other accounts by messing with the "Forgot Password" feature or calling and manipulating support/customer service.
Only use trusted web services, and give them as little sensitive data as possible.
If you shop online, try to delete Credit Cards when you're done using them, don't keep them saved in the account.
Use Two Factor Authentication (2FA) for higher value web services (banking, email).

Advertisers can:

Collect information when you login to them.
Track you across different websites you visit without logging into them.
Track you via GPS on your phone.
Track you online via WiFi on your phone.
Track you offline via WiFi on your phone.
Track you offline via credit/debit cards.
Track you offline via reward/membership cards.
Some of the security (or privacy) threats with advertisers are opt-in (i.e. you accepted it) and generally advertiser tracking isn't going to mess up your day. Problems arise when advertisers sell your information on to third parties (who in turn sell it to other third parties), go broke and auction off your data, get hacked or are victims of mass surveillance.

It's worth noting that their revenue models would be colossally damaged if everyone ran adblocking software.

In response you can:

Not create social media accounts, or create accounts with false information (although you'll still have the same friends, so are still opting in big time).
Disable third party cookies in your browsers.
Turn off GPS on your phone, or use a custom rom to limit which apps have access to your GPS.
Turn off WiFi on your phone, or use a custom rom to limit which apps have access to WiFi.
Turn off WiFi when you're out and about, especially in malls/shopping centres.
Use cash.
Debit cards tell your bank what you're buying and who from and where, and they sell that.
Credit cards tell VISA/Mastercard/etc what you're buying and who from and where.
Don't use reward cards. Most people never use the "rewards" and your privacy is worth more.
