Thanks for the answer.

I did all of the above and it didn't work. The websites address:

www.sunsara.pl

But the problem occurs when you start opening any of the links there links. They need like 15 sec every time.

http://sunsara.pl/kontakt/ http://sunsara.pl/wyprawy/ etc.

Please note, that I'm getting the same problem on 2 different pcs and a mac, and that the site runs well on all other browsers.

Could it be a plug in issue on Wordpress?

...What is even funnier, as you can see, when you click on these links from here, the site loads immediately. But when you use the same links on the site, then it takes time...

I tried to access http://www.sunsara.pl/ and my anti-virus blocked it.

I've called the big guys to help you. Good luck.

You may have ad / mal-ware. Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

Ok, but how can I remove ad/mal-ware from a website by running a scanner on my pc?

That is in case something got into your system.

Hi again

Yep, that’s exactly what happened – my website got hacked. There were some malware scripts installed.

The problem is now solved at the site runs well on Firefox again. Sucuri might still show the sites status as malicious, but I can see it didn’t change status since yesterday. All the other checks show the site is clean. Maybe it’s because Sucuri wants to sell their product for 199 $?

ps. of course I received right away a friendly e-mail from ”Jane Tancinco” at fixrunner.com, who would clean my site for 49$. I suggest to stay away.
