I’m having trouble removing this virus. Can someone help? The virus is not allowing the removal tool to run even in safe mode.

This malware is one nasty bug! Niether my AVG or Norton online will touch it. Luckily, I was able to uninstall it with my Revo uninstaller (I love my Revo), but all this allowed me to do was finally lock the trojans in the virus vault. uninstalling it did nothing for my computer whose symptoms include: not being able to access my security center (I’m running Vista…long story), damageing two of my apps, and taking over my firewall. My computer is dragging so bad. I need to know how to get rid of the virus part of this fake app otherwise NOrton is going to charge me $150.00 to remove it. AVG and Norton both have virus definitions dictonaries… If any of you’ll know these virus’s names will you email them to me?? [email protected]

This SUCKS!! Im almost tempted to file a DMCA complaint. According to the IPP act of 1996, spreading this kind of stuff is a federal offense. I do hope they get caught.
