Sorry if the following is a bit vague but it seems that Prevx is causing these crashes. Basically, if I open any browser on my system (Win 7) including IE, Firefox, Opera or Chrome and navigate to an https: page the browser spontaneously crashes and I have to restart it. After that it usually (although not always) behaves properly. If I turn off Prevx before opening a browser, no problems. I suspect that SafeOnline is involved here but I'm not clear how to troubleshoot the issue. I've tried turning down the protection level in SafeOnline but it doesn't seem to make much of a difference. Any suggestions please? I'm running Prevx 22.214.171.124, Avira pro and Zemana as the only other security progs.
