I created two websites and check on them often when making changes. I have been using Firefox for some time (and may switch back to Internet Explorer). When I visit one of my sites, no problem. When I visit my second website, it says "Webpage Attack" and this just started happening. And when I visit this same site on Internet Explorer, I do not get the "Webpage Attack" message. It didn't happen before. The software that I used is by Serif Webplus 10. I went to the Serif forum and got all kinds of suggestions, about clearing my cache--which I did, as well as the history, cookies. When I visit this website on my cell phone, no issues. My webhost said that a virus--Blackhole Exploit Kit was in the code and it was being used against me. He stated that my website had been hacked. Then, one of the forum members stated that the server my webhost uses could have been hacked. I run my virus software everyday and it still didn't detect a virus. I even found info on YouTube about how to remove the Blackhole Exploit Kit virus and followed the steps and I still didn't have that virus on my computer. So, I need help, because I do not get a "Webpage Attack" message when I look at my website on Internet Explorer and neither have other people when they visit it.
