How can I avoid that a virus read out all passwords memoried by Firefox? It was happend two weeks ago!
My children where using some web sites about games to solve some problems. During this use a virus came via web interface into my desktop. My virus scanner shows this but could not avoid that this virus read out all my accounts memorized in Firefox and sent it into dark channels.
I could restore the way how my accounts leave my Desktop. There was some accounts only memorized into Firefox inclusive passoword. These accounts would used from other persons in the meantime.
My questions are:
- How save are the memorized accounts-password combinations?
- And: Is it possible that the Firefox Sync Account can transfer the virus from PC to PC by using the same Sync-Account? Or can I be sure that all other Firefox installations at other PSs will be clean after this attack at one Firefox-Installation during all installations use the same Sync-Account? What this question means in background: Via Sync can Plugins be installed at other systems. What happens, when a virus install a special virus-plugin? Would Sync it move to all other PCs?
Best regards, Frank

If you are using Sync to sync passwords then you likely aren't using a Master Password to protect the password.
If you suspect such a virus infection then you should cleanup your computer and change all the compromised passwords immediately.
Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.
