Upgraded to Vista, have used Symantec Corporate for years, older version of the software, 9 I think. Not vista compatible, and I no longer have access to the latest version. A couple of weeks ago I tried NOD32. Ran pretty good, fast, but it was buggy, has issues with lots of simultaneous connections and messes with them. Googling I found where people have to turn off parts of it. I'm not paying for something that's glitchy and known not to work 100%. So that got nixed off the list. And I uninstalled it. Tried Avast. It seems to run good, fdidn't immediately seem like it interfered with my system or performance. But now Remote Desktop is broken... I terminated all of Avast's modules, and I can't remote desktop in from work, or even in from other computers on my local network. These two apps are the only things I've been tweaking with the last few days. Mostly used my home computer for playing Oblivion and SupCom. Going to be real annoying if I have to reformat to clean them out =( Those apps had way to much complexity, all kinds of modules and shit, I guess going back to a simple focused AV-only app is best. Symantec v10.2 I think was updated for Vista =( I'm not paying out the ass for a 5pack, why is mexico'ing it the only option they offer.
