I downloaded what may have been a malicious extension on Google Chrome. I don't know if that was a legitimate extension or not; I got it in order to access Pearson, hand-typing a link that another student (with no motive to prank me) showed me (am I a victim of typosquatting?). I was able to remove it from Chrome, which is a step above what I've seen another similar malicious extension do on another computer. How do I know if it is really gone?
If I am the victim of something malicious, is there any way that this could have compromised my Google account? I have that intertwined with a lot of things, including my university account. If so, what should I do? Is there any information that I have to go off of to justify buying a new computer?
The name of the extension was "Safe Search." The publisher is "Safely." It wasn't "Search Safely Search."
