The most simple method to resolve this issue is to remove the profile the viri is found in. It uses the appdata folder to nests itself in and then popups with all kind of solutions.

Also there the advice is remove the cached profile and rename the roaming profile. Then the user loads a new profile and all will be good again. You can also run ESET online virus scanner of another free online scanner to be sure that the virus left the building.
