My home computer was hacked, passwords were stolen and some online accounts were breached. That computer will be formatted and the OS reinstalled. I changed passwords on all of my accounts and other computers immediately after discovering the attack, however, it is possible that the attacker had remote access to my office PC.

While I don't notice any problem (i.e., the computer seems to be running "normally"), I need to know if it's safe to use my office computer.

Can someone help me determine if my office pc is clean?

Thanks!

I don't believe I transfered any exe files but yes, I did run a flash drive between them.

Were the password or account Numbers from the office stored on the home unit?

The passwords were not stored on the home unit but the attacker did have access to my office password because a keylogger was installed on the home unit. I connected to my office PC from home via VPN and RDP so the keylogger would have picked up the password.

I am about to run the ESET scan and will post results when finished.
