During the installation, under "Additional Options"
uncheck "Install background guard" and "Install scan via context menu".
Launch Ewido
On the left side of the main screen click update.
Click on Start and let it update.
Then Run a Complete System Scan
Some Antivirus scanners cannot remove infections because you are online and
they are running on the system when you perform the scªn.
If you have problems with the infection returning you would be best
downloading these scanners and running them in safe mºde.
