Now that I had time to surf a little the problem was not cured! IE7 still crashes intermitently. I have been trying to deal with this for the better part of a week now. I have worked with a support group called Ctrlcenter, and in the process run countless scans with Malwarebytes, SAS, Combofix, Hijackthis and Avira Antivir. Found and removed a couple of trojans (TR\Dropper.gen and TR\Fakealert.AQE.16) early on and a handfull of their garbage, but all scans for the last few days find nothing. I have tried running IE with add-ons disabled and it still crashes. The people at Ctrlcenter said they think its a virus that is new enough not to have made it into anyone's definitions yet. Meanwhile they have given up. What can I do now?
