Sorry that you've been hit with the so-called "clipboard virus"... Sadly, you're not alone... The number of transactions is staggering
Removing malware can be really problematic and time consuming... I usually just back up important data like documents and photos and then reformat the computer and reinstall the operating system.
But if you try the well known apps like malware bytes and spybot (google: malware removal) you might be able to locate and remove the malware. Personally, I recommend reformatting as it guarantees the virus/trojan/malware is gone... if you try and remove and miss one piece, it might come back :-/
