I tried to post here a few weeks ago. Got message that post needed to be approved by moderators, but it has never appeared. I too have been using the Eset Online scanner for several years, since ver 2 came out I have had to stop as it crashes on 95% of machines. Does not matter what OS they have. Just tried it again today and same thing.
I have consistently been having this issues with the Online Scanner V2, never had a problem with the original one. Crashes like in the OP's post in Vista, W7, W8 and W10. Happens in both safe and regular modes. Also has no bearing on whether an Eset product is installed or not.
