I have archer c2300 router.

I keep getting attacked by the following virus

classification: SSL open ssl chacha20-poly1305 and rc4-md5 integer underflow -1.1 (cve-2017-3731)

A lot especially against laptops. sometimes 10 or more times an hour.

so far trend mico has listed this so evidently its not getting in but I wish i knew what it is and whether to worry about it.

thanks.
