Do I need to deploy antivirus and anti-spyware software to all the PCs on my network?
Solution 1:
Modern Anti-virus software should already provide anti-spyware countermeasures. Symantec AV Enterprise, which is what I use on Windows based PC, does.
Solution 2:
I think you get the biggest bang for the buck just by using the Microsoft provided anti-spyware solution, Windows Defender.
It has the following advantages:
- Updates pushed out via Windows Update
- Supports Group Policy
- Free
- Supports Windows XP and up including Server OSes
Alternativley you can look at Microsoft Forefront Client Security which provides an integrated anti-virus and anti-spyware solution.
