Yea, SON was doing the same crap as it was doing before for me earlier today.
As mentioned earlier: http://www.son240sx.org/forums/showpost.php?p=390080&postcount=73
The site is no longer infected;your browser is likely hijacked and your system itself is infected.
I have been using the forum at work and it hasn’t messed anything up.
Once again the site is not at fault here from what I can tell; you are most likely infected earlier and didn’t notice it.
Full scan your system.
i just reformated since my comp went nuts hopefully it doesnt happen agian.
Please continue any discussion on trojans and whatnot here: http://www.son240sx.org/forums/showthread.php?p=389851#post389851
Leave this thread for any issues arising from the upgrade (and not trojan related)
