As the bad folk discovered to use Autorun on USB and other media, Microsoft turned off the autorun feature. Some folk turn it back on and find these viruses or other things again.
Stock settings mean we have to help such viruses install. Is there more to this story?
As to why AVG doesn't catch it, what if it's just an autorun, batch file and autorun is enabled? No antivirus stops that!
To remove a virus we have to know more about it. As to autorun, you need to turn that off. Here's how:
My AVG couldn't catch some virus from USB flash drive.
The virus copies the real folder, creates a shortcut for it and hides this shortcut.
So you can only see infected folder, which is visible and seems like initial one, but is not initial.
Who faces this type of virus and what did you do to remove it?
