With threats that increase in both number and diversity, it's necessary to make sure your computer and the data stored on it are secure.To this extent, not only that you must keep an antivirus with real-time protection capabilities running on the PC, but also make sure its virus definitions are up-to-date.F-Secure Virus Definitions updates your copy of F-Secure Anti-Virus 5 and F-Secure Anti-Virus 4 with the latest virus signatures and detection and removal technologies.It is recommended you update F-Secure Anti-Virus regularly to ensure constant protection for your PC against new threats that appear.There is also a new breed of threats on the Internet, such as carefully planned targeted attacks that can pass through conventional security solutions unnoticed, possibly taking over your computer for illegal purposes.
You need to have at least version 8 - older versions have security vulnerabilities (click on the Sophos shield and select 'About Sophos Anti-Virus' to check which version you have). Ensure you install the correct version of Sophos for your specific MAC e.g 10.7 and lower OR 10.8 Regardless of which operating system you use, if your computer is connected to the Institute network, you have a responsibility to make sure your computer is as secure as it can be.
Please note that the virus definitions do not update themselves.
In other words, to update again, you must download and run the utility once again.
The offline definitions can be used in situations when the Internet connection is down.
In this case, the automatic definition updater in each F-Secure product will not work, since it cannot download the signature files from the F-Secure servers.
