I've tried just about everything to get ESET to play nicely. Even disabling the entire suite doesn't help (tried disabling the firewall first, then the AV, then both, and then other parts of the app). Eventually, I disabled the entire suite to no luck. So, I'm switching to Norton's Security Suite (which is basically Norton 360, that and because it's free from Comcast for subscribers). I'll still use ESET on my other machines, its just this particular machine I use for all of my business/work stuff, and that includes banking. My other systems are used for gaming and programming, so this wasn't an issue for them, so I'll simply keep ESET on them because I don't need to access my bank's website from them.
And, this wasn't a problem up until about two months ago. So it has to be some update that was installed by ESET (for the Smart Security 4.0 system), because it has worked fine from the time I got ESET (back in April) until about two months ago... and I don't think it's related to Windows update either. So, I've come to the conclusion that there is a problem between my bank's website and ESET (I don't have the problem logging into other SSL-enabled sites, like Hotmail or Gmail).
Anyway, Went ahead and put Norton on the computer, and things seem fine now. I guess it's better than some of the other AV apps/suites out there like TrendMicro and AVG, but it certainly isn't the best either.
