avast 4.8 use too much CPU ?

[FulValBot]

my avast 4.8 use too much CPU and sometimes my mouse lag -.-

is a new bug of this version? i have windows vista ultimate 32 bit. on italy sp1 coming on april. for now i have already applied all updates from windows update, also all nvidia hotfixes.

I don't think there is a bug. If you open Standard Shield, which is the file being scanned?
Do you use the Home or the Pro version?

[FulValBot]

home edition.

and my pc is not a slow pc.

My system is no racehorse and I don't see that (it also isn't running Vista though), what other security software are you running.

[Lisandro]

Please, answer...

If you open Standard Shield, which is the file being scanned?

Did you set the Standard Shield sensitivity to High or it is on Normal level?

[FulValBot]

high level. there is also spybot installed.

[DavidR]

I would set it to Normal, the default, which provides the best balance between protection and performance and what I have been using for just under 4 years.

Spybot S&D (if that is what you are talking about) may have an impact on your system if you have the resident part of it enabled (disabled by default). Wehen I used it I didn't have the resident function enabled.

[Lisandro]

high level.

So... maybe this is the reason for the high CPU usage like David said.

I would set it to Normal, the default, which provides the best balance between protection and performance and what I have been using for just under 4 years.

Spybot S&D (if that is what you are talking about) may have an impact on your system if you have the resident part of it enabled (disabled by default). Wehen I used it I didn't have the resident function enabled.

i don't use resident protection.

[DavidR]

Then it shouldn't impact on CPU unless you happen to be doing an on-demand scan with S&D, so your issue if the High sensitivity you have set in the standard shield. Set to Normal and test.

[Lisandro]

i don't use resident protection.

Of Spybot? Ok, but the better will be letting Standard Shield at Normal level and not High...
