I just downloaded the free trial and am glad the program is detecting dangerous malware, but I am getting poppups every 15 seconds…how do I stop this? please help
Unless your system is heavily infected there is no reason you should be inundated with pop ups. The pop up setting can be found under the settings tab on top. But every 15 min means your infected. What does the alert say?
this sounds like a siref rootkit infection …
start a new topic in the virus and worms section …and in that topic you do this
follow this guide and attach (not copy and paste) the requested logs http://forum.avast.com/index.php?topic=53253.0
