URL?

[ChuckRJr]

What free tools are available to supply information about a URL.  I would like to investigate the source of URL's that come with junk.

Hello ChuckRJr,

There is several oneline tools available. Try out one of those:

https://safeweb.norton.com/

https://global.sitesafety.trendmicro.com/

https://www.virustotal.com/en/

https://www.f-secure.com/en_US/web/home_us/search

Also, Google's Safe Browsing Site Status:
https://www.google.com/safebrowsing/diagnostic?site=URL (replace URL with the real URL of the site you're investigating, or use https://www.google.com/transparencyreport/safebrowsing/diagnostic/)

and the hpHosts database:
https://hosts-file.net/?s=Browse (use the Find/Search box, site classification codes are detailed at https://hosts-file.net/?s=classifications).

Better to not rely on a single source, some databases can be slow to update (I've seen some databases where checks haven't been done for 6+ months on many sites, also sites that have been clean for over a year still flagged as malicious, the worst culprit was McAfee's free online checker, SiteAdvisor, I don't know if it still exists in an online format. Norton can also be slow to clear false positives and reclassify cleaned up sites).
