Have you shopped online via the affected computer?

If your checking account, debit card or credit card account information was used to shop online, it would be best practice to close the account and open a new account.

Have you banked online via the affected computer?

If yes, it would be best practice to go to a "clean" computer and change the password. Alternatively, to protect the account, go to the login page of each banking site and enter an incorrect password until the account is locked. This will ensure that no unauthorized access is gained to the account until you can make contact with appropriate support personnel.

How do you connect to the internet?

If the internet connection is constant, it can be disconnected from the computer to ensure no communication happens between the malware and the source.

Were there debit or credit cards in it?

You will need to cancel them right away. Look for instruction or phone numbers on past billing statements or issuer websites.

Were there checks or a checkbook in it?

A stop pay can be placed on checks and/or the account closed.

What other sensitive items may have been inside which may prompt a protective action?

Driver's license or ID card

Cell phone

Social Security card

Insurance cards
