Avira vs avast vs avg reddit4/15/2023 In some cases, those mistakes have wreaked as much or more havoc as the Avira blunder. Last September, Microsoft's Security Essentials and Forefront - its consumer- and enterprise-grade antivirus software, respectively - issued a faulty malware signature update that deleted Google's Chrome browser from thousands of PCs.īefore that, all three of the world's largest antivirus companies - Symantec, McAfee and Trend Micro - had shipped defective definitions. The company will reportedly investigate to uncover the root cause of the massive blocking before re-enabling the feature.Īvira isn't the first antivirus vendor to cripple or damage Windows systems with a flawed update. "I've been a big proponent of Avira within our company, but I think that may change when it comes time to renew our license in a few months."Īccording to the same support discussion thread, Avira's fix simply disabled ProActiv. The whole company ground to a standstill," reported someone identified as "AaronH" in a Tuesday message on Avira's support site. "This update has been pretty catastrophic. Avira's free antivirus software, which has limited functionality - and does not include ProActiv - was not affected. The inadvertent blocking impacted Avira Professional Security, Avira Internet Security 2012 and Avira Antivirus Premium 2012, paid products priced between $30 and $60. Even worse, ProActiv prevented critical Windows files from running, which in many cases "bricked" PCs, or kept them from even properly booting. Users quickly reported that the updated ProActiv was blocking almost every legitimate Windows executable file - those with the ".exe" extension - meaning that most applications refused to launch. The service pack included an update to ProActiv, a behavioral-based monitoring system that watches for suspicious events that may hint at a malware attack or point to an infection. Avira is the world's second-biggest antivirus maker, according to usage statistics.
