Problem with Sophos Virus Definition on Wednesday, 9/19
A virus definitions released by Sophos at approximately 1:20PM on 9/19 contained an error causing it to identify its own auto-updater as malware and to quarantine it. It also found the Adobe Flash updater, Apple software update and Chrome update and others are also being mis-detected.
Later that afternoon Sophos updated its Live Protection feature to whitelist the files incorrectly identified as malware. This will allow the previously flagged software to function normally again, although old entries in the Sophos quarantine list may remain for these items. These entries can be safely cleared.
Users that are still having problems with software functioning properly can run the Sophos Settings Update Tool, available from itservices.stanford.edu/service/ess/pc/sophos to make sure the Live Protection feature is enabled.
Users that took action on the alerts they saw and moved or deleted some of the incorrectly flagged software will likely need to reinstall that software. Please submit a HelpSU request for assistance.
