Sophos antivirus mac not updating

Please NOTE: If you already have Sophos installed, you do not need to download the new software manually.Just modify your update server settings to the new servers which are listed under your Operating Systems download page and Sophos will automatically upgrade for you.While researching inter-process communication on Mac OS X, I found a small security issue with Sophos Anti-Virus for Mac: any local user can remove arbitrary files on the system via the Update functionality of the product. I started by listing all Sophos processes on my Mac Book: All except GUI run as root and are unsandboxed! So if some user creates a symbolic link to some sensitive file owned by a privileged user, it will be deleted during the update procedure since the process doing deletion (unlinking) runs as and is not sandboxed.Trustwave security advisory has proof-of-concept code that removes root-owned file via this vulnerability.Sophos Labs have detected over 1,000 threats for Mac OS.Sophos Anti-Virus for Mac Home Edition runs in the background and scans files for threats whenever your Mac opens them.Version: 7.2.1C Threat detection engine: 3.12.11 Threat data: 4.59 Release date: November 1, 2010 Protects against 2111062 threats Prior to even downloading the downloadable installation check over the Tech Specs page to verify that your system is up to par with what the software supports.

For more information please see the Trustwave security advisory:https://

After downloading the Sophos Anti-Virus for Mac DMG (filename: savosx_72_size:~62 MB) it is highly recommended that you invoke Terminal, change to your Downloads folder and generate the message digest using the command md5 savosx_72_and match the checksum on the Sophos Tech Specs site (at the time of this writing) it is 21c3c6f2d93d0843238b9575792e06ef if the checksums do not match it is possible that the DMG corrupted during download, has been tampered with, or someone dropped the ball on synching the download page to the file.

A quick tweet to could help fix that although no guarantees.

To fin out how a simple world-wide web search for: Substitute the part for the name of the anti-virus software you want to uninstall.

This will give you a link to the information you need to remove it.

It comes with an uninstaller (Applications/Remove Sophos) in case you want to remove it after trying it on your system.
