Welcome to PCHF volcano!

Can you follow the PCHF Prework link in my sig and then post a Hijackthis log back here and a AVG spyware report. Then a member of the security team will help you.

Moved to HJT logs forum.

I don't know how to use HJK

It tells you in the PCHF Prework link in my sig.

I have a notepad file of HJk now

What should i do ?

go to file>edit> select all then >file> edit>copy> then right click in the reply box on here and click paste
