I also have the shutdown problem issue with F-Secure, but I will NOT disable the Tamper protection!
As many have said, it is a default protection (Tamper protection prevents malware from disabling the antivirus), disabling it is crazy and opens a door to infections...
It's like the self-defense module of an antivirus, never disable it.
I fully understand you
@Shadowra , but after F-Secure themselves even officially find this option as stated: "
temporary " acceptable safe and also recommend it ( I do not, but I will try to explain better why this time in this post ), at least for being able to error search because that in and by itself is 100% understandable, and people will always click on options/features that is possible to disable no matter what it is. The good part around this forum, is that many of the members are curious geeks and nerds and normally have a good security hygiene and setup with layers anyway. They can also both read and grasp genuine and relevant security information and recommendations, but here's the key part I think F-Secure or at least one of their employees seems to have forgot in this specific case!
When a default protection feature, no matter brand or vendor or even product as this can even in parts correlate to safety/security features in cars etc. If a default security protection feature is turned OFF to try error search and quick fix a noticeable problem for those users/customers that actually have it, it's a direct major big time risk,
that specific feature will be forgotten and left OFF. In a case where this users/customers or company for any reason for example, may it be clickhappy or simply ignoring basic security messages etc, actually gets infected and have their system not just compromised but even have their credentials stolen and it was that specific default protection button that could have in the end saved them.
With all that said, I must mention that I like this thread and extra much those users that genuine even took their time and energy to try help and constructive inform F-Secure about this odd and weird problem also on their own official forum. For now, I would 100% state for those users that see and notice this issue (
don't forget those users that have zero problems with it ), it's no longer any point in turn tamper protection OFF even for error searching because F-Secure officially now been super crystal clear that a patch/fix is just around the corner. Turn it OFF now, is very fruitless but of course a personal decision. Please just try to remember also turn it back, ON. It's today one of F-Secure SAFEs default main protection feature also in the home user products. The feature exist for several reasons and I personal previous sent F-Secure a very disturbing report on how easy it was to nuke and destroy a system with SAFE as the main layer, without tamper protection.
