I found this forum through a google research on tuvtu.dll. I did this research because i recently got infected by a trojan, which shutted down my Wifi application and my antivir so i couldn't go on the internet anymore, neither upgrade my NOD32 which couldn't eliminate it properly.
I formatted, reinstalled, and got the last AVAST. I ran a full scan on start since all my Documents folder was on my 2nd hard drive, had not been formatted, and could still contain the virus.
Avast found it and remove it all... i hope...
No more problem, but i have a popup on each start which says that rundll couldn't access tuvtu.dll. It's "normal" since i got rid of it, but what isn't normal for me is my rundll still looking for this file...
Can someone help me make sure my computer is clean ? Thx...
