Look, what's that over there? Sophos nips Windows DNS DLL false positive in the bud

A Windows operating system library was wrongly identified as malware by Sophos's antivirus scanner for some users on Tuesday. The main gripe seemed to be bogus alerts generated by the software, rather than crashed systems, a not infrequent side-effect of erroneously putting Windows library files into quarantine. Influential UK infosec geezer Kevin Beaumont highlighted the cockup, and soon after El Reg began prodding Sophos about the issue, the false positives were cancelled and normality was restored. How much pain, confusion and general inconvenience did the incident cause? Probably not much, it would seem, mostly because the issue was quickly resolved.
