By "i cant use malwarebytes" i meant that i cant know when im entering to a site with a virus on it, when i had the trial, it told me when a site had malicious things. Now i feel unsafe
Also, it did not only install those files, but it replaced my Firefox shortcut with another one, that seems to be also installed with the rest of the stuff, i know this beacuse when i entered, it told me about plugins of avast and it opened in a malicious search page
