Actually had this issue my self. what you need to do is have Google give your phone its own password.
Login to your Google acct from a PC, then from the Account Overview page find Authorizing Applications & Sites, click edit
once you are logged in there you will be able to set up an Application Specific password.
Its not Malware or a virus, it is just Google being overprotective.
This would be the case if you set up two-step authentication on your Google account. Otherwise you should not need to set an application-specific password on the account. Fredba should know if two step authentication was set up on the account; if so, that would definitely be an explanation.
