Im using Avast 5 Home edition and something weird is happening…
Now and then when i click on some program files on a backup drive it says they are infected with this virus and sends to the chest.
Now ive done a FULL virus scan twice and nothing is picked up yet now and then it still detects this in one or two program files. Is this a false positive?
You got a real infection. You need to format and start over with a clean reinstall of your OS.
So back up all your personal files onto a disk or CD (Do not back up your files with a USB stick and do not back up any executables, music or video files. Only back up documents).
MBAM is not a antivirus…
Did you have any antivirus program before you installed avast ?
Did the computer come with norton or McAfee installed when new?
if so, have you removed/uninstalled it ? and run the corresponding uninstall tool to remove all traces from the program
