Before you visit the Lockdown Corp. website by clicking on a link from this site, there are a few things I believe you should know.
Information That You Should Know About Keith Little
In late 1998 a man known as Keith Little, sole operator of a web page known as pchelp attacked and harassed LockDown Corp., it's officers and our LockDown software on his web page, news groups, forums and in personal unsolicited email.
Just as he has done with other companies, the attack on LockDown Corp. and our software was made BEFORE he had EVER tested or even installed it.

The "Click Here" link leads to a rather extensive amount of commentary and rebuttal, aimed squarely at the PCHelp website and its proprietor.
The popup trick is accomplished by use of your browser's transmission of the "Referer" when it sends a request for a web page. Most browsers, notably Internet Explorer and Netscape, send this information with every followed link, by default. It reveals the URL of the page just visited.
Any website log may store Referer URLs as a routine matter, and many websites track Referers. But the targeted treatment of "pchelp" visitors suggests that Lockdown Corp. could be giving those visitors special attention in other ways. The same script that triggers the popup could quite easily produce a log of its own, execute network queries to identify the visitor's ISP, query the user's system for network names or file shares, etc.
Visitors whose IP address is fixed should know that any subsequent visit to the same website can easily be correlated with the any and all prior visits. Referrals from pchelp site(s) to Lockdown Corp. could very easily cause the user to be "tagged" indefinitely as someone who's been exposed to the information at pc-help.org. Dialup users will usually have a more variable IP address, but their ISP will remain identifiable. Cookies can enable tracking as well.
Naturally, Lockdown Corp has every right to treat its visitors however it likes. But I believe visitors to my site should understand that they'll be specially recognized (and perhaps specially tracked) by the Lockdown Corp site when they go there from here.
My advice, if you wish to circumvent Referer tracking, is to do any of the following:
Referers are sent to any website, not just Lockdown's. This is a useful thing to be aware of where your privacy is concerned. Happy surfing.
