Hi everyone,
I bought a laptop off Kijiji and ever since I've brought it home it's been lagging, and now these popups are happening (shalledition.club) I googled it and it said it was trojan and to download malware removal. I don't know much about computers in the sense of what to download to remove it. Can anyone please tell me if there is any safe and effective malware removals that won't essentially mess my laptop up more than it is? Thank you.
