My Trend Micro virus scanner found a presumed virus in c:\\Programs\\boinc\\client_state_next.xml .... Do you think it's an antivirus misunderstandig or it's really an infected file?

Thanks

client_state_next.xml is as far as I can find, a file that is being written to multiple times a second, before its contents are written to the client_state.xml file and the former file deleted. Then the next second it's made again, written to multiple times a second, contents written off to elsewhere and deleted.

That may look like virus activity.

Since you can slow down & corrupt any project's crunching with an active AV scan on your BOINC directory, it's best to leave the whole BOINC directory out of the scan path of the AV scanner.

I use the (free) AVG6 utility from Grisoft.cz (Czech company). It doesn't offer that degree of configurability, but it's not needed: AVG has never had a complaint about any BOINC files. OTOH, it does supposedly vet XML files in real time, and that might have something to do with the intermittent CPU bottlenecks I've noticed, esp. with the Einstein plugin. Until yesterday I thought it was only with the Einstein plugin, but last night it happened (things grinding to a halt, even text entry) again while the SETI plugin was front and center. At that, it's quite intermittent and random.

That's probably because AVG6 is quite old and no longer updated. AVG7 Free is the latest and is updated almost daily and does allow you to exclude files & folders. I am using it.

I was mistaken and forgetful: I'm using version 7.
