Not sure why I downloaded this as I had AVG which was considered really good. But this one found stuff AVG didn't.
Installed it on my new PC too as it started running slowly and it found a trojan that 'coincidentally' arrived with a Windows update. Thanks Microsoft. The new PC has McAffee on it and until this program found it McAffee didn't have a clue.
