Hi, I currently have a very bad virus on my computer which wont allow any virus checkers, malware searchers or registery searchers to run. Ive also tried online virus checkers and it will not allow any downloads and causes firefox to crash. When I try to use a virus checker it does not load, and when i use MalwareBytes it says "enumerating registery objects prior to scan" and then closes. And once i try to open it back it up it says i have lost permission to use it. I have also tried to use the virus scan on Avira Rescue CD but it scans to around 15000 then shuts down. Can anybody help me?
