Well, today I got to bring the computer away to repair.
The internet wasn't working normally anymore!
Only was online about 20% of the time!
I think the virus has destroyed some parts of the internet configuration.
I dont know how much repairing it will cost and how long it'll take!
You could always boot into safe mode and check/recover your flashdrive there. Just make sure hidden and system folders are visible to see if any malicious content is there, as well as check the autorun file.
How to make the system files on a flashdrive visible??
Is it also possible in normal mode?? (not in recovery-mode)
I only know how to make hidden files visible.
What antivirus do you use by the way, if any? I cannot help, though, as I haven't gotten a virus in a while. Sometimes, however, I just relied on system restore to get rid of viruses, and it happened to work. It might be leaving traces of viruses there, though, and some viruses actually destroys system restore points.
All our system restore points are saved on an external database, still 1TB free space for backups and sys restoring points. That external database was not connected to the computer when the virus appeared!
and my anti-virus-program is, as I already wrote, Kaspersky Lab 2012
