It mentions Avast up to 7, while I currently have version 8 installed.What's strange is that update used to work just fine up to 2 weeks ago, which makes me think something in my network has been changed without me knowing it.

Do the rules apply to any request, a client address set or all domain users? That can make a big difference! In which mode is ISA server installed: Web Proxy/
Cortafuegos Herramientas Suites de Seguridad Blog Foro 11 de abril de 2011 Tweet Avast Antivirus bloquea el acceso páginas web por error. Una actualización del Antivirus Avast! publicada durante el día de hoy Lunes 11 de Abril, ha causado https://www.infospyware.com/blog/avast-falso-positivo-hatml-script-inf-110411-2/ un error en el programa que bloquea el acceso a varios sitios legítimos, https://www.404techsupport.com/2011/04/latest-avast-definitions-contain-false-positive-blocking-legitimate-websites/ desde las redes sociales, sitios de noticias, e incluso el mismo Google y hasta InfoSpyware :(. El problema es específicamente en el “Escudo”, parte del programa que protege contra sitios Web maliciosos, que comenzó a detectar erróneamente la presencia de un malware HTML:Iframe-inf en algunos sitios web después de aplicar la actualización 110411-1. Si bien error 403 al momento de publicar esta nota no ha habido ningún comunicado oficial por parte de la gente de Avast sobre este error, según lo que reportan en la página oficial de Avast en Facebook, la actualización 110411-2 ha sido puesto en libertad y soluciona el problema del Escudo y los bloqueos a las páginas webs, pero muchos son los usuarios que a través del Foro y Twitter se quejan error 403 avast de no poder actualizar su antivirus y que reciben un mensaje de error 403. Seguramente ese error 403 es debido a la cantidad de solicitudes para la actualización que hay a la vez que sus servidores no dan abasto, pero seguramente se ira solucionando con el correr de las horas al igual que el funcionamiento de su foro oficial que esta inaccesible en estos momentos. Los que puedan actualizar, lo verán así: Ante un problema como este, las opciones de solucionar esto momentáneamente hasta que se logre poner la nueva actualización, es la de deshabilitar manualmente la “Protección Web” en la interfaz de anti-virus. Obviamente, esta opción también deshabilita la protección contra sitios Web realmente maliciosos, pero se puede andar con cuidado durante unas horas hasta que se corrija el problema y así poder seguir disfrutando de la net. Otra solución más drástica es desinstalar completamente el antivirus e instalar otro de los Antivirus Gratuitos. Lamentablemente para los usuarios, los programas Antivirus al igual que cualquier programa desarrollado por el hombre no son perfectos y nunca lo serán, por lo que todos en algún momento pueden presentar este tipo u otro de “Falsos Positivos” que preocupan erróneamente y hasta interrumpen con el correcto funcionamiento de

Definitions Contain False Positive Blocking Legitimate Websites, Malware Detected [Updated] April 11, 2011 While it's nowhere near as bad as the McAfee False Positive problem that ended up killing tens of thousands of Windows XP PCs, the latest Avast definitions (4-11-11) seem to be blocking tons of legitimate websites thinking that there are malware scripts embedded in them. Tons of people are reporting the issue on Twitter and the Avast! website is being hit so hard, it has been intermittently down or slow to load. If you visit a site that is detected, you might see this pop up in the bottom right corner of your PC and then the website will go to a "Problem loading page/the connection was reset" error page. This is happening across browsers and operating systems from reports I'm seeing. These are the definitions that I'm running that are causing the false positives. The scripts are all running on legitimate sites (not that means they're malware free) but they don't seem to have a whole lot in common. It would make a little more sense if a common script like the Twitter Tweet button or the Facebook Like button were flagged as a false positive but the problem seems to be these antivirus definitions are too broad for their definition. Avast! I still love you but this needs to get fixed. Communication would also be key. I'm not seeing anything on the Avast! website, blog, or Twitter account currently. I hesitate to recommend it but the only way around this is to get into the Avast User Interface and under Real-time shieldswebshield uncheck the box ‘Sca
