So far I've been unable to find an x64 compatible Anti-virus - anyone have any suggestions (I've tried Norton, AVG and one that comes with my internet package )
The new avast! 4.5 Home/Professional now fully supports the new Windows 64-bit Windows platform (avast! Server Edition has been supporting Win64 (both AMD64 and IA64) platforms since version 4.1). ALWIL Software is anticipating massive start of this platform as Windows XP 64-Bit Edition will support up to 32 GB of RAM and 16 TB of virtual memory, enabling applications to run faster when working with large data sets. Applications can preload substantially more data into virtual memory, allowing rapid access by the 64-bit extensions of the processor. This reduces the time for loading data into virtual memory or seeking, reading, and writing to data storage devices, making applications run faster and more efficiently.
