My mom took a thumb drive to a drugstore that shall remain nameless until I can be sure the virus came from there, but she brought the drive home and it immediately crashed her computer. I watched a fully updated copy of Free AVG scan the infection "windo.exe" and do nothing. I installed another free product from antivir.com and it removed all the infections. This really makes me mad, virus software should find known viruses. This is not an old virus, it has been known since 2009. There is just no excuse.
