Several times over the last few days I have accessed this [BA Executive Club] forum and have then been automatically redirected to a different page, for instance this one
http://testscanningtasks.pl/690zm52/...84cb2/pr2/196/ (do NOT click on any dialog on the page if you view this, close your browser window).
This page, or similar pages have indicated that Microsoft Security Essentials or McAfee security "has scanned my machine and found that it is infected".
Now, I work for McAfee and know that no such thing has happened.
This is what is known as a malvertisement and or "fake AV" and it is a scam, as my machine is NOT infected. The way the scam works is it says your machine is infected and if you pay a fee it will clean your machine. After you pay, hey presto! you're told your machine is clean, when it likely was all along. It does not clean anything.
You may want to look into who is generating these advertisements on your web site before it gives you a bad name through association.
