Clicksor Ad virus/trojan issues?

My members are complaining that clicksor was giving them viruses and trojans. So I switched to Chitka and got a horrible payout (crappy audit system), and went back to clicksor where the problem started again!
I know if I email my rep they will handle it (ask for ip of ad bla bla), but this keeps happening…wtf is this site doing? I really like cliksor as I get a high pay out but wtf these ad viruses are retarded!
Anyone else have a good alternative or fix for this problem? (Cant use google adsense)
