Why ULAV is killing my IS

martink

I have this eeePC with 900 Mhz Celeron running Win 10 and FS - IS installed on it. I do not use it daily, but a couple of times a month.

My problem is that when I turn it on updates are killing it.

If there are uninstalled Windows updates available, downloading and installing takes all CPU and disc access. However, eventually it get updated and there are not always new updates.

 

The other updates are FS IS updates Those are available mor frequently and they, too, are killing it

 

This is after the CPU has leveled, but the nothing can be done because ULAV is using disc access.

 

I've installed IS so at first I wondered why is ULAV there in the first place.

Re: What happened to ULAV?

Hello  ! Ultralight engine is now the core of FS AV, ulav not intended to become a GP AV.

 

ULAV is part of IS now, so it is OK that I see it, but it does not help with the performance.

 

Still would like to know if my installation is OK.

Secondly can I do something about it other  than just having the eeePC on daily even if I do not need to use it? Eventually after a day to two the performance is not reduced by the updates anymore.

An option could be the use of aother  lighter cloud based AV like Immunet, but would that give less protection?

 

I do have ULAV on other PC's, but I use them daily and they are faster so I do not see such a performce problem  with them.

Hello,

 

Sorry for my reply. I'm also only F-Secure user - so, it is only my own suggestions.

 

But it is not a ULAV -> only UL.

With meanings that "F-Secure Ultralight AV" is certain solution where Ultralight-design is introduced originally. It is still 'actual' beta-solution(software) while Ultralight-design is added to main stable F-Secure solutions (Home/Business).

 

So, noted components with name like "Ultralight" with meanings that it is part of such Ultralight-design; But it is not a "F-Secure Ultralight AV"-solution.

And only Ultralight engine (core/design/technology).

 

I feel that it was (?! screenshot and main troubleconcern) large update or upgrade for F-Secure Internet Security (next build or so). Or updates for main Ultralight-core. I'm not sure does it should be with such impact; But compared to daily Aquarius (and other database-engines) it may take some resources.

With my own experience -> it was also with such view with not daily use. Boot up system and got all of updates -> take too much time and system resources at once. But I feel that F-Secure with tries to tweak it.

 

Also, my feelings that main design of Ultralight technology (core) about other part of solution. Not directly concerned optimisation updates-handling. And this view has really improved.

Maybe your installation is OK (except potential compatibility troubles with other software; or some internal troubles).

 

I'm not sure about any workarounds -> because most likely that anyway installing all of available updates are needed. And it will take certain time and resources.

As potential workarounds -> after large delay with using system -> boot up system with disabled Network then check that system is loaded OK -> then maybe switch F-Secure solution to 'Game Mode' (maybe should reduce tries to check updates too briefly) -> check Windows Updates at first;

Even maybe good to check F-Secure updates before Windows Updates (because -> maybe system updates are not triggered from first also; and maybe possible to postpone it).

I think that F-Secure will download some of critical updates for engines (Aquarius-core can be with postpone-delay); And potential updates for main cores like Ultralight Core or Online Safety modules. AND maybe for upgrade-check (from build to next build).

Of course, except workarounds like potential improves by F-Secure.

What about """""lighter cloud based AV like Immunet, but would that give less protection?"""""

Does it Talos/Cisco tool? If yes -> maybe that give less protection then F-Secure IS in general. But maybe this solution with changes about design/features - so, not sure a little bit.

 

Thanks!

If I have it on once in 1 - 3 weeks it appears that there are always FS and MS updates to downloaded and installed and I just have to live with that and have the eeePC up more frequently and allow time for the updates.

 

These are the updates which were installed during the time of limited response.

This week without network connection the CPU looks like this

After 10 - 15 minutes that levels at

After connect to LAN the updates started again

The FS updates were already installed at that point

 

With the faster PC with the real ULAV the Microsoft modules installer can also have a high CPU value, but that does not last as long. A bigger problem is that when the PC is on for a day or more Firefox and Thunderbird CPU can be more than 50 % each at times. Fortunately restart of the program solves that for another day.

Apparently one contributing factor is that this particular PC is single chore sing thread. On another slow PC the updates only take 50 % of the CPU which is 2 core.

Hey,

Just to expand on Ukko's answer: not only is F-Secure Ultralight AV a different thing than the Ultralight core running inside F-Secure SAFE/Internet Security, the two are also incompatible. If you manage to install them on the same machine (by somehow managing to install the beta Ultralight AV product on a machine with a regular F-Secure AV product), there is likely to be conflicts and the setup may break. The installers are supposed to detect that they conflict with each other and uninstall each other.
