Unity 5.3.0 crashes. Why?

I launch it, it crashes and bug reporter window pops up. IDK what happens.Unity tells to delete Lavasoft Web Companion, but it didn’t work. Neither pressing alt nor allowing unity through Firewall worked. tell me anyone how to solve the problem.

Where having the same issue, it crashes around 50 times a day. No consistancy to crashes just random. I now save everytime I change a single value
