Firefox zpomaluje počítač (?)

[Kitty]

Nedávno jsem tu řešila problém s pomalým počítačem. Vše se nakonec jevilo OK, jen počítač byl během první půlhodiny pomalejší. Myslela jsem si, že mám špatně nasaveného Spyware doctora. Pak se zničehonic začaly stránky ve Firefoxu v základním stylu (pardon, nevím, jak to pojmenovat) - bez obrázků, bez framů, jen velkým písmem psáné odkazy. Nepomohlo odinstalovat a znovu nainstalovat, ale zjistilo se přitom, že be z nainstalovaného (nikoli spuštěného) Firefoxu počítač šlape jako hodinky, po instalaci se zase zasekl.
Dočasně používáme Operu, ale rádi bychom vyřešili problém. AV nic nehlásí.

Mám dát log i bez nainstalovaného MF?

Zkoušela jste reinstalovat FF pomocí MozBackup: http://www.slunecnice.cz/sw/mozbackup/ ? Ta utilita reinstaluje komplet, tj. vč. smazání profilu a opětovného nakopírování.

[Kitty]

Děkuji, zkusím.

[Rudy]

Zatím není zač.

Buď jsem něco udělala špatně nebo to nezafungovalo

[Rudy]

Máte v systému 2 antiviry. 1 odinstalujte, může způsobovat sw konflikt.

[Kitty]

Jako AV používáme pouze AVAST, pokud zároveň běží ještě něco, je někde chyba. Co je ten druhý? Nicméně problémy byly i před instalováním Avastu. Zdá se, že nainstalovaný Firefox už systém nijak nezpomaluje, ale stále se nedá používat, s tím bych moc ráda něco udělala.

[Rudy]

Ten druhý je AVG. V logách ho najdete. 2 antiviry v systému spolu zpravidla kolidují a mohou způsobit zpomalení.
