AOL has released a new version of Active Virus Shield that runs like a dream on Vista. But it’s not available on the official download site. However Neowin and Softpedia seem to have the updated version. You’ll also need to sign up for a free activation code. But we recommend doing that after you download the file (which should be AVS_v25.exe, not AVS.exe), just to make sure you don’t accidentally download the wrong file from AOL. Of course, if you’re running Windows XP, download any version you like.
