Recently I have beeen away from home and accessing my e-mail using webmail. 90% of my attempts to log in fail, with a message 'CAPTCHA authentication failed' .The host login displays a CAPTCHA symbol on the login screen, but there is no requirement for any input, no letters to copy, no photos to ID. Then I noticed a message on my browser suggesting that login is failing because of a conflict with AV software. After some correspondence with the host the conclusion seems to be that Avast and CAPTCHA do not get along too well. Is this a known issue? If so, does anyone know how to overcome it? Thanks.
