Some anti-virus programs do not like the way Reva is compiled, leading to "false positive" reports from time to time.
Before you report a virus problem in Reva, please run it past another virus-checker besides your accustomed one. I am 99.99999% sure that there are not, nor have ever been, any viruses distributed in the Reva package.
If you get two positive results (from different checkers) please email me immediately or file a bug report so I can look into it. Please include the exact name of the virus checkers which reported the problem, as well as their version numbers.
