I've been running ESS v3 for a year with no trouble at all. I got a mail from BetterAntiVirus.com to renew, which I did for 2 years at $75.99. It was only after I installed ESS 4 that I found out it wouldn't allow me to connect to the internet I've re-installed v3 and all is well. After looking on here I see it's a very common thing to have no internet after upgrading and that the lack of support is overwhelming. When is ESET going to actually do something constructive about everyone's problems? I only wish I'd checked here before paying out my money.
