Hello, I did something dumb and downloaded a crack thinking KAV would warn me if it was actually a bad file, so when I got no warnings I installed it and something took control of my pc for a few minutes (I can provide the link to the download if needed). I know it somehow got access to my facebook account, probably through browser cookies since a password change ended the suspicious activity. Now, the only problem that I have is that sometimes my google searches are redirected to scam sites (amazon loyalty program), has happened around 3 times today on my pc and even 1 time on my phone! I have already scanned several times and used other antimalware software but keep getting 0 results after the initial hits and quarantines. Is it possible my router was hijacked?
