After update to ver 87.0.664.52, it cannot open any more. How to fix it?

MGubitzer Ok, this was a quick one:"Thank you for contacting Trend Micro... This is a known issue and our development team are working on a fix as BM is indeed blocking it - you can try and add the following exclusion "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe".A fix for this issue will be released."

Same problem here.MinPham And of course setting an internet browser as a trusted program and thus disabling behavioral monitoring on it is a security problem.I hope, TrendMicro is releasing a new pattern soon, which fixes this false positive.

Hey, everyone! I wanted to hop in here and thank y'all for these reports! The team is investigating on our side now, and highly suggest you follow the steps that TrendMicro provided to mitigate this in the interim. I've verified that answer in this thread, but I will also link here again (it's been listed here a few times now) the support article that you should follow. It's in Japanese, so you will need to use the translate feature to read it in any other languages. I'll follow up in this thread once I know of any fixes put in place! Thanks again for these reports. :3 Missy Quarry (she/her/hers)Community Manager - Microsoft Edge

same issue here. if u stop officescan agent and turn it on again, it works well, but officescan agent says it has to do an update. if u do the update, u can not start edge again.

We added 'C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe' to the trusted programms in officescan. Now it works with updated officescan agent.

Regards

  45PM91 Thank you for your solution. Is there any security issue when adding Ms Edge to the trusted programms in Officescan? It is an internet browser

The same here. It is due to TrendMicro's behavior scan (Office scan).

  MichaW2000 You're right. It is due to TrendMicro's behavior scan (Office scan). I temporarily turn of Edge update. How's the next
