I have three backdoor trojan virus on my computer which reads as follows: 1--OLDER,exe LOCATION, WINDOWS 2--Explorer.exe LOCATION, C;\windows\explorer and number 3--explorer [1].exe location c:windows\`temporary . How do I get rid of these nasty things? They are all in quarantine but don't I need these files? Please make an explanation simple as I am a novice and an old one at that. Thanks in advance and this is my first post . ( I have Norton Anti Virus and Zone Alarm installed now)
