Of course, even if you do pay, you may not get your documents back. For example, they may display a warning, purportedly from the FBI or another agency, stating that your computer was used to send spam or view porn, and demanding that you pay a fine before you're allowed to use it again.
Even worse are the ones that encrypt your entire computer, rendering it useless unless you pay to have it unlocked. Overt ransomware threats encrypt all your pictures and documents and demand that you pay to get them back.
Some malware programs literally hold your PC or data for ransom. Typically, these posts include an inflammatory statement of some kind, like "OMG were you really that drunk? Look at this picture!"

Not every site redirect is malicious, but if you find that trying to reach DuckDuckGo or Google takes you to an unfamiliar search site, you've got a problem. Other times they contain links to malicious websites that will attempt to drop more malware on your PC. Sometimes they're ads for legitimate products, netting an affiliate fee for the adware perpetrator any time someone clicks on the ad. While not as common as they used to be, adware programs bombard their victims with advertisements. Software isn't perfect, and sometimes a brand-new zero-day malware attack can slip past your security, at least until the purveyors of your protection push out an update.

After a while, things start to get messy. Oh, you may have to clear out some crapware that came pre-installed, but that new PC is humming along at its most effective.
