F-Secure Ultralight Hoster slows down my computer

Hi,

 

the F-Secure Ultralight Hoster process comsumes a lot of disk-resources, so everything else is very slow. It takes a long time to start any application.

 

Is there a way to stop that?

Hey,

That process essentially is F-Secure Antivirus. Most likely either database is being updated or your system is being scanned. Does this happen frequently?

Re: F-Secure Ultralight Hoster slows down my computer

That's the F-Secure automatic system scan, I think. If it bothers you, either reschedule it for some other time, or turn off scheduled scans and do it manually whenever you are going to be away from the computer for a while. You can change the settings for automatic scans under Tools - Scan Settings - Scheduled Scans (at least I assume that's what the options in question are called in English, my version is in Swedish).

 

Unfortunately, I don't think there is any way to turn off the scan mid-progress, except by killing the process from the Task Manager. That's my biggest complaint about F-Secure: there is no interface for the user to control, monitor, or even be aware of, scheduled scans running.

Hello,

 

Sorry for my reply. I am also only F-Secure user (their home solutions).

 

Just as sidenote: it is possible to 'cancel/stop' scheduled scan by enabling Gaming Mode (currently).

While it is not work with 'context manual scan'.

If scheduled scan process is about scanning large/zipped/packed file -> Gaming Mode should be enabled certain count of time. If not - enough some seconds. Then it is possible to 'disable' Gaming mode (rightclick F-Secure tray picture -> Gaming Moder under menu).

 

Also, recent changes with Scheduled scan are pretty good. For example, "Recent events" should be with visible strings about 'launch' and completed/canceled states; and there is certain tweak option for less performance impact.

In fact, there are many feature requests on subject (as example):

Thanks!

Re: F-Secure Ultralight Hoster slows down my computer

Same thing is happening to me.  Each day when I wake my PC (I rarely shutdow, just have it sleep) the Disk usage is maxed out by the F-Secure Host Process with a sub process called "F-Secure Ultralight Hoster".  It seems to take anywhere from 10-15 minutes before I can even open a web browser.

 

I set antivirus scans to happen at 3 am.  Does F-Secure not wake my PC to perform, or is this some other kind of definitions update maybe?

 

Doesn't seem to "Ultralight" if it consumes 100% of disk resources.

Hey,

I don't think the product wakes your machine to scan but instead scans later when the machine wakes up

I think that it should be possible to check if it is 'scheduled scan or not' by "List of Recent Events" (and start-point flyer should be visible at launch).

For Windows platform: https://help.f-secure.com/product.html#home/safe-windows/latest/en/close_scan_wizard-safe-windows-la...

 

Maybe your experience is about something like such discussion (since your experience about 'sleep mode' and not about restart system or even shutdown):

https://community.f-secure.com/t5/F-Secure-SAFE/F-Secure-Host-Process-100-CPU/m-p/107537#M19042

 

While it is not an explanation, but as potential reason (for except if "definitions update" take too much unexpected resources and time).

 

Thanks!

Re: F-Secure Ultralight Hoster slows down my computer

For me it's not disk resources. At first it use whatever CPU is available, usually arount 60% of 8-core 4 GHz AMD FX-8350, and around 2 GB RAM, I have 16 GB and total usage about 50%.

Could your disk usage be swap-file if you don't have enough RAM, for me 0% disk usage.

Re: F-Secure Ultralight Hoster slows down my computer

Hello,

 

there's only one way to work with my computer: turn off f-secure. After that everything works in an aggreable way and speed. I've started my computer some minutes ago and the most disk usage was from f-secure and I have to wait until I can start only a simple browser. Sorry, that's not for what I've paid for.

And is this your thought for supporting a problem? A forum, where other users canguess what it might be, but there is no help from the company directly how to do to solve this problem?

I have bought this software for many years but now, it's time to change this.

Hello,

 

Sorry for my reply. I'm only an F-Secure user (their home solutions).

 

There is option to receive official and certified support by F-Secure:

chat as example. With addition as fsdiag (https://community.f-secure.com/t5/Common-topics/How-do-I-create-an-FSDIAG-file/ta-p/18190) -> possible to investigate situation and to find certain explanation or some fixes.


I feel that this Community is not like a forum (even most of forums are community in fact).

But, yes, there are quite active official F-Secure Staff with their responsibility area. And probably most of topics can be with tries to perform 'silent' internal investigation. But direct ask for Support their official support channels may boost up situation.

 

Also, as part of discussion -> maybe good to know your system/hardware configuration.

I've started my computer some minutes ago and the most disk usage was from f-secure and I have to wait until I can start only a simple browser

And does it with known count of minutes? I mean how long it was not possible to start use system with expected view (or start a browser)?

 

With my recent experience (laptop is not used some weeks) -> it was possible to launch browser immediately. With maybe two(?) minutes of system launch as ability to see shortcuts/logos of desktop; and with some 'lags' during use later (unknown count of time - since I did not surf speedy).

 

Thanks!
