I HAVE A PROBLEM MY PC IS CONSTANTLY Restarts INSTALL AN ANTIVIRUS E (AVAST), but try to run, my computer is restarted, what should I do?
Have you tried starting your computer in safe-mode (by holding F8 button during startup)?
Hi, Why no try make an scanning with an tool as kaspersky rescue disk or avira rescue CD, this are antivirus that scanning your PC before the start of windows. This are not best that avast but can help you in this problem because I am sure that is a problem with an boot virus.
English is not my language. Bye
Why do users come here and never come back to read what we post? 
I don’t know, because this is a forum with a big number of users with a great knowledge of avast and technology and they can help to users easily, and for example, this post anyone responded for more of one week ???
