I've just rolled out version 0.99.2 of ClamAV packages for CentOS 7. Nothing particularly new or important about this release, but it'll stop ClamAV from complaining about an old version for a while (a week or two until they roll a new version that'll complain about an old version). There were enough changes in ClamAV to where I wanted to give folks a heads up about the upgrade, just in case it causes problems. I've tested it on our systems, obviously, but there's a pretty wide variety of ways people can be using ClamAV, and there are a couple of things that changed that might effect some of those use cases (I patched it to act like the old version on the command line, but there may be other differences).
Anyway, keep an eye on your anti-virus usage and lemme know if you see any problems.
I'll roll this version out for older CentOS distros soon, as well.
