You will see that your link has been filtered out by the forum filters. I don't know why, maybe banned words, banned web sites, (previously spammed in these forums), or any other reason, and I am not asking why.
While we appreciate the warning, it seems you have just visited today to post this, your only post in these forums. That makes me wonder if you have a 'mission' to spread the word against these people around the internet.
Your post serves no purpose here, and so I am locking it. Other Mods may decide to delete it.
Just had a phone call here in the UK from these guys, who tell me my internet link is running slow and that they can help speed it up. They then told me to click on 'Run' and type 'prefetch' in to the command box. Up come the 'prefetch' list and this guy tells me that these are junk files!.
Now - Prefetch files are essentially a resource list. Any time a program is executed, Windows XP will attempt to find a pre-existing prefetch file, and if it's available, it will use it to make the application load up faster. The file will also be updated after it is accessed, so that the more an application is used, the bigger the drop in loading time (to a point). If the application doesn't already have an associated prefetch file, Windows XP will create one. Those files are stored in the \%windir%\prefetch directory. One important note is that the process depends on the Task Scheduler service. If the Task Scheduler service isn't running, the prefetch mechanism isn't used and the files won't be read or updated.
Now you decide - Junk or not - These guys are conning people into selling them software. They operate in the US, UK (where I live, Australia and New Zealand (http://www.supportonclick.com/).
I'm an IT Consultant who hates this sort of thing so beware of these people and don't take them on.
