during the past 2 weeks my computer was infected and i've posted requesting help, but after few days i couldn't wait so i reinstalled my system using the recovery CD , i updated the system as supposed and now it is getting very very slow and i have Malwarebytes and some other protections like ESET but they couldn't find any thing ! but i noticed in the registry (MozillaPlugins) string which is every where !! it is all over the registry, the strange thing is that i've never used Mozill or had in my computer !! any way i deleted the strings again and again and again ... it keeps coming back , is it the reason why my system getting slow or is there something els , any help regarding this issue will be appreciated .
thanks in advance
