This isn't the first time I've heard of this error. I've never been impressed with Panda either. I'd just remove it all together. That's just my 2 cents though....
I've always liked Panda... their customer support (the one time I had to contact them) was phenominal. I emailed them that a certain webpage would not work when their firewall was active. After about 3 days of trying various things, they issued me a patch that fixed the problem. Keep in mind that the product was already as fully up to date as I could make it... so this patch wasn't readily available... they must have written it after I brought the issue to their attention.
