I got a recent email that Dividends4Life was thought to have infected a reader with the Prunnet Virus. I found one of the ad networks that I use exhibited suspicious behavior and removed it. I Googled it and found it had been a source of Malware in the past. I have pulled all ads from that network.
If you have recently visited Dividends4Life, I recommend you scan your computer. The person who was infected cured their problem with the free malwarebytes anti-malware software.
I hope my actions have solved the problem, please let me know if you observe any suspicious behavior while visiting Dividends4Life.
