Three things: 1. Yesterday I uninstalled AVG antivirus programme and installed Avira. As well as the Antivir PE Classic, I also have the above, shown on my desktop with the same white umbrella on red background. When I clicked on it, it wanted me to run it. I became suspicious so put the name in Google. A site said it was malware - is this correct? 2. After installing Avira Antivirus, I ran a scan of our computer and the programme found 5 vuruses - 4 X TR/Trash.gen trogens and 1 X TR/Killav.28714 trogen. I'd attach the report if I could find it. All these were quarantined and then deleted from the quarantine folder. 3. The Avira Report also said that the hyberfil.sys and pagefile.sys files could not be opened. Is this a cause for concern?
