Rularea a două produse antivirus de pe acelaşi computer poate degrada performanţa şi provoca instabilitatea sistemului. Este important ca orice antivirus instalat anterior sa fie dezinstalat din sistemul dvs. înainte de a instala un alt produs de securitate. Dezinstalare tipice utilizând instrumentul de eliminare Windows (Add / Remove Programs) este adesea insuficient.
