It would seem Performersoft.com yet again, want to join the scareware group, this time it seems they're not content with their software doing it - they want their adverts to do it too.
This one popped up whilst I was investigating a site earlier, yet again like the rest, going through ad.yieldmanager.com;
With the advert itself being server from;
IP PTR: 22.214.171.124-static.reverse.softlayer.com
ASN: 36351 126.96.36.199/18 SOFTLAYER - SoftLayer Technologies Inc.
Doesn't appear to be anything other than this rubbish on the IP, and they clearly don't want it easily found - absolutely nothing other than an HTTP 403 on the homepage.
First and foremost lets make this clear - DO NOT CLICK ON THESE ADVERTS - THERE IS NOTHING WRONG WITH YOUR COMPUTER. If you're actually having problems with your computer, there are plenty of forums that will assist you for free;

As for performersoft.com, all you've done is get yourselves blacklisted - again.
And as for yieldmanager.com, given they've apparently got somewhat of an obsession with not properly checking who they're serving adverts for, or indeed, what adverts they're serving, you can quite safely blacklist them if you've not already (those using hpHosts will already notice they're already blocked).
