When opening webmail talktalk and trying to send or receive email, a message comes up saying, Adobe flash player security has blocked this action because /about/srcdoc is trying to communicate with this internet-enabled location - static.adsafeprotected.com
This warning message keeps appearing when trying to do anything on my webmail
I really appreciate your help. This does help as it is exactly what is happening. How much of a risk is it unblocking?
How much of a risk is it unblocking?
If you select a single site to allow, not much, as long as it's a trusted site and you're careful about what you open there (in this case it being mail, you need to use your own discretion). If you set Flash Player to allow ALL sites, then you may be opening yourself up to anything from spyware to outright viruses.
