you can go to most any crack sites here are a few
newcracks.net — Newcracks offers a variety of annoyances such as third-party cookies, adware/spyware, browser exploits - not to mention a plethora of trojans in the downloads.
cracklooker.com — Cracklooker in itself isn't a direct threat; however, they don't host any cracks themselves, and search queries will direct users to sites that should be avoided.
astalavista.ms (or any ‘astalavista' domain or variant thereof) — Same as above. Searching on Astalavista will display results from sites that should not be visited. Best to avoid. Other Astalavista domains are even more dangerous.
crack.ms — Browser exploits and hijacks, popups, trojans, backdoors - you name it, it's here.
thebugs.ws — Contains some very harmful affiliate links.
needcrack.us — McAfee says, "When we browsed this site, we found direct links to an address that made unauthorized changes to our test PC." Marvelous.
cracksearchengine.net — Not a direct threat (it's a crack meta-search site) that aggregates search queries from less reputable sites. Clicking on search results can be harmful.
anycracks.com — Makes unauthorized changes to the PC. Marked as an ‘exploit server'.
mscracks.com — The works! Ad popups, browser hijacking, trojans in the files and bad affiliate links.
keygen.in — Same as above.
Dailykeys.com — Bad affiliate links and files are purposely infected with trojans/virii.
bestserials.com — Even Google confirms that "this site may harm your computer".
crackfound.com — Ad popups and bad external links.
cracks4u.com — Affiliate links are on the bad list. Trojans and other malware are purposely added to the crack files. Avoid!
getcracks.com — Same as above.
keygen.ms — This site itself is harmless (aside from some popups); however, the actual crack files are linked on unscrupulous sites whereby an entire gamut of problems can arise.
crackhell.com — Their in-site search links to warezdownloads.com (not a good sign), and most of the affiliate links (which take up the better part of the homepage) should be avoided.
crackspider.net — Does not host any files - search results include those "Oem software" scams, or crack download links to abominable sites such as mscracks.com. Avoid.
crackzplanet (net/com) — Malicious executables are commonplace among the available cracks.
asta-killer.com — Categorized as an ‘exploit server' with active threats.
