Eset online scanner is a bit different than the others in that you need to either use
IE or download and run their smart installer if you're using another browser. Then tick
the radio button that says "Enable detection of potentiall unwanted application"
Then click the link that says "Advanced settings", then check all the boxes except the
one that mentions "Use custom proxy settings", unless of course you're using a Proxy
Server. Then just click "Start", it will do a thorough system scan so it takes a long
time.
