How do I get rid of this virus?
We thrive on information and with the lack of it we are guessing.
What Operating System are you using ?
What is the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?
Check the avast! Log Viewer (right click the avast ‘a’ icon), Warning section, this contains information on all avast detections.
Why couldn’t you get rid of it when avast detected it (what errors were displayed, etc.) ?
If you did not select “remove to chest” or even if you did
rt click the ball and update>programs (just to make sure)
then open avast and schedule a boot time scan
send any hits to the chest
post the log
