For product:
F-Secure Antivirus and Mobile Security are really good products, but are lagging in the last 6 months in the detection rates the top products somewhat behind (in several independent tests incl. Real-world tests). {However miss some top product 100% Erkennugsrate sometimes chopped / trojaned Apps, eg We have Mobile Security.}
The firewall in F-Secure Internet Security is like almost all 'Internet Security' products not too tight and not much better than the Windows firewall. (So far there are only solutions firewall specialists instead antivirus specialists and Kaspersky Internet Security from 2013 positive exceptions.)
Positive at F-Secure is now even that F-Secure is not an American or British company, and was not incorporated in the US. In addition, the terms and conditions are acceptable and not corrupt almost the complete privacy incl. Presumption of innocence. (Lockout Security, Trust Go and Co would be the complete opposite, regardless of their promises at the beginning of those Terms and EULA here.)
