This has happened 3 times now over the last 2 weeks.

Not sure if my Malwarebytes program is now detecting more than it did before or something has crept into boinc.exe.

Anyway having looked into the web service that provides bounceme.net domains it does not look like something I want to allow.

Anyone else having similar detection messages?

It only requires a very small amount of code to match something suspicious to do this. If the false positive is reported by enough sources then a subsequent update will resolve this. On and off various security programs have falsely identified quite a few files from various projects as being dodgy as well. On the CPDN forums users are advised to exclude boinc program and data folders from scans as locking a file at a critical time can cause errors as well as the false flagging of files.

have same malwarebytes version but not seeing any problem with boinc. what projects are you subscribed to?

Have you visited Tomas Brod's project website? He recently reconfigured it and maybe he let something in he shouldn't.
