DON'T allow any "untrusted" connections. Deny them all.
It could be a random man-in-the-middle hijack of your connection to Cryptsy, trying to grab your log in but doubtful since 2 factor login is usually setup on accounts.
Or they could be lurking on Cryptsy's connection waiting for their next target.
Or it could be merely a temporary technical issue.
Try another known safe browser 1st: (Firefox or Internet Explorer as long as their fully updated and current).
Be sure this is the link to Cryptsy your using:
https://www.cryptsy.com/users/login - the one I use, the normal log in page for Cryptsy.com
Cryptsy - Backup alternative Login#2
https://www.cryptsy.com/users/login/users/balances - this one is for when the 1st one gives the 501 error, or whatever that error number is. Seems to solve that often.
Either of the above in Firefox will result in the green padlock and green colored "Project Investors Inc. US" in the address bar if your connected to their https connection. IF that dark shaded padlock in .I.E address bar colored green isn't all there in the address bar, or a green padlock isn't in Firefox along with green colored "Project Investors Inc. US" then your not on the correct site and someone is trying to scam you.
Of course that Trojan may not be completely eradicated either, your av may have merely deleted it without undoing all the changes it may or may not made to your pc. Maybe try System Restore to a known prior Restore Point.
Or maybe the Trojan messed with that browser and changed it's settings.
Or maybe if it is a real man in the middle they will give up sooner.
Occasionally last year that would occur to my PCs.
Usually running Ccleaner and rebooting seemed to solve it, or it just went away on it's own.
It you messed with setting your Internet Security Firewall to scan encrypted connections in it's advanced settings this could also result in an "untrusted setting" warning when trying to connect to https:// connections such as Cryptsy's log in pages.
It could be merely hackers scamming in your local area. Maybe if nothing else solves it when you go to sleep unplug the cable modem/dsl cables, both. Replug them in 8 to 12 hours later. You are likely to get a new IP address this way in some areas, sometimes sooner, sometimes it takes longer to be re-assigned a new IP address this way. Some ISP's may still issue the same exact IP anyway when you plug everything back it. Disconnect all wires from the Modem to A/C and the incoming coax/dsl-phone type cables, but you can leave the router to modem cable connected, but unplug the router a/c cord too. Reconnect the modem 1st, wait one minute until all regular lights are flashing that can flash/stay on, then reconnect the router a minute later. Have all pc's/tablets/phones shut down if possible too so none get the same IP assigned address by mistake after restarting.
Try the above, go from there. Work the problem through this list.
