Untested, but if you are happy using ClamAV the following should work:
Install the ClamAV (enabling EPEL repo first):
yum install -y epel-release
yum install clamav
Then you can update ClamAV:
/usr/bin/clamscan -r --infected /
--infected (-i): Only print infected files.
--recursive (-r): Scan directories recursively. All the subdirectories in the given directory will be scanned.
It's worth noting that by default
clamscan does not remove files, you would have to manually set the switch:
Regarding scanning for windows signatures in linux I will refer you to this accepted answer on AskUbuntu: Does ClamAV Scan Windows virus?
In practice however, you will mainly use a virusscanner to protect your Windows partners. ClamAV does scan for Windows viruses as well.
