Hello! I'm looking to reinstall NOD32 on my desktop. I had 2.7 and liked it, however there were some quirks when trying to run on Vista at the time. Reading the forum, it looks like 3.0 has a few quirks as well. At this point, would the expert advice be to try 3.0 on a Vista box, or 2.7? Is there any security risk in using 3.0 at this point (is it less secure / less effective)? Thanks!
