Sophos Anti-Virus is Stanford's site-licensed anti-malware software. It can protect your computer against viruses, adware/spyware, and other malicious software.
Sophos Anti-Virus updates itself automatically so your version of the program and the virus definitions are always up-to-date.

Scan your computer
Sophos Anti-Virus scans each file as it it accessed so it is usually not necessary to regularly scan your hard drive. However, it is recommended that you scan your hard drive after installing Sophos in order to detect any viruses and malware that may already exist on your computer.
- Click the Sophos icon in the upper-right area of your screen and then click Scan This Mac.
- A window opens that shows the progress of the scan.
Sophos Anti-Virus is preconfigured with the optimal settings for on-access scanning in the Stanford environment. However, you can change the settings for your situation if you wish.
To change the default preferences:
- Click the Sophos icon in the upper-right area of your screen and then click Open Preferences.
- Click the lock in the bottom left of the screen if it is closed and then make the changes you wish to the default preferences.
Excluding Thunderbird files from on-access scanning
The Sophos Anti-Virus installer checks for directories containing Thunderbird data files and will exclude them from the On-access scan to prevent significant slowdowns when reading your mail (the mailbox format Thunderbird uses is susceptible to this problem; the format Apple Mail uses is not).
After installing Sophos, if you install Thunderbird and create a new profile or if a new user begins using Thunderbird, you can manually create this exception.
Make the Library folder visible
The user Library folder is hidden by default. You need to unhide it to see the the folders containing the Thunderbird files you want to exclude.
- Open the Applications folder and navigate to Utilities > Terminal.
- In Terminal, type chflags nohidden ~/Library and and then press ENTER.
Note: To re-enable this feature, run the chflags hidden ~/Library command in Terminal.
