BilleB Posted April 18, 2009 Share Posted April 18, 2009 uninstall Ccleaner and reinstall by right click on the Setup program and install as Administrator. This should solve the problem Link to comment Share on other sites More sharing options...

Kristabelle Posted April 19, 2009 Share Posted April 19, 2009 I downloaded CCleaner this morning, but everytime I start a scan my computer freezes up. What am I doing wrong? Kristabelle. Link to comment Share on other sites More sharing options...
fische Posted April 20, 2009 Author Share Posted April 20, 2009 My daughter's dell laptop continued to act up. After trying to run various virus scans, etc that were followed with critical errors I then went to safe mode and tried same. OS went into a loop and kept saying there was an error in windows explorer and needed to restart Win explorer. Shut system down. Went to restore point. Still same outcome. Then spent most of the day reinstalling Vista, drivers, etc. Since machine is relatively new. Not to concerned with what may have lost. So far, everything appears okay. Actually seemed to run quicker. Ccleaner ran without issue now. Still need to complete the virus & malware scans. Hopefully all set now. Thanks for help on malware follow-up.
