Last question i have a friend that has important movies and stuff on his pc, he has been affected with this virus but he has no way of backing up his stuff. is there any way on how to remove it without formating and losing everything?
1. Make a thorough bootscan with AVAST first before doing a backup. And allow it to delete all infected files. Don't worry your movies won't be deleted.
2. After it's done with the cleaning, your system will continue booting.
DONT ALLOW IT TO CONTINUE BOOTING!! Turn-off your system immediately before it completes the boot-up process because Vitro still exists.
3.If you wanna backup in a clean environment without any worries about vitro infecting in the background, You download LINUX UBUNTU. Burn it, boot it, and do all the backup from there. It has a simple burning utility that should be enough for your purpose. But don't backup HTML/HTM files and EXE files especially exe files below 100KB in size because most Virus passes AVAST detection. that's all.
Off topic: I just found the funniest Vitro removal guide in the following link!
skip immediately to the Vitro manual removal instruction part for the best humor
