Sam, thank you very much. I
tried the 2nd method you taught me and it worked!
It found 3 more viruses on my PC: Java_Nocheat.A,
Java_Bytverify.A & Troj_Muss.A.
The first one isn't serious.
I got rid of the 2nd and the 3rd virus, by using the solutions Housecall told me.
My pc is working very nicely now and I'm very happy. Thank you very much again!
