Yeah of course, I went over all other computers that accessed my account. The only connections were my PC and my laptop which is a mac. But mainly this computer. The mac I will deal with later on the main issue is my PC.
The results I have back from the Cloud AV's are:
Trend Micro HouseCall:
Found a Trojan - TROJ_GEN.USEHJ21
ESET Online Scanner:
Found Win32/OpenCandy application.
What are these? Problems? Big problems?
Yes, they sound like problems.
Look, if you want to make sure the PC is clean, you will need to nuke the HDD (formatting the HDD is NOT enough) then reinstall the OS. I know it is a pain in there, but I would not take any other chances if I were you. you could download the files you think you will need in the future, but keep in mind those files may harbor the infection as well. Hence, after you download them, isolate the backup disk from any PC connection for the time being.
Afterwards, you can proceed nuking the HDD by low-level formatting it using something like Killdisk, for instance. That will zero the HDD and render it to a factory-like state. Run that 2-3 times in a row, just to be sure (you can download Killdisk and burn a CD with the bootable program, then boot from that CD). Then you can proceed with OS installation.
After that, you can run a scan (using the latest updated AV program of your liking, running from a CD, as mentioned before by the others)of your backup disk to ensure no residual infection persists on these files; do NOT boot the OS while doing this. You could actually disconnect the system drive while booting from the AV disk, and run the AV on the backup disk. I know it sounds paranoid, but remember what just happened here and what brought you here to begin with.
Good luck with this project. You might choose to just run the AV as mentioned in above posts without going through this new install, but if it happens again the bank might get antsy about your accounts being hacked again. And you'll end up here again, anyways.
Do not ignore that Mac. It is possible that the hacking happened from that one, as well. They are not as secure as most people think; hackers' conferences remind us of that yearly.
