Ok, so I was browsing the web when I noticed a popup with 'Congratulations you won ...' and something. I'm used to these kind of adds, so I didn't pay much attention and just closed it. Then I noticed the same add appearing on various different sites (like when I'm checking web-mail and stuff), so I thought it might be some sort of malware. I've scanned with Avast, different anti-malware applications and they don't find anything. It seems like the stuff appears just random and not on every website (shows up in Chrome as well as Opera). It also states something like "xxxx.vodonet.net". If anybody has any information or experiences with this stuff, please give me some advice.
Thanks very much in advance.
