aliexpress redirect malware

first i want to thank you guys for this great anti -virus

second i wanna ask about aliexpress redirect malwares

because i was having a lot of trouble trying to figure out why when i start out my PC

it opens firefox and redirect it to aliexpress site

and i don't know why bit defender doesn't pick it up

when i got time to do my search i found it something is manipulating the task scheduler

and i delete anything that ends with site..i broke things but the redirect is gone!

but after that i install iobit advanced systemcare>>and this morning when i start up my PC

It try to redirect and bit defender prevent it! log(firefox.exe attempted to establish a connection relying on an unmatching security certificate to We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.)

my questions:

is bitdefender free protect the task schedule?

2.and how to get rid of aliexpress redirect malware because i don't know if its from iobit advanced systemcare because i found it add 3 tasks 2 of them Ads pop-up and i deleted them😑

or other apps or maybe extensions on Firefox😓

thanks again😁
