Rundll computer issues?

Rundll errors in Windows can be very frustrating and may slow down your PC. Rundll files are integral to native processes on a Windows computer that involve Registry files. Malicious programs can attach themselves to Rundll files and damage, delete or corrupt them. This in turn can cause slow performance and frequent Rundll error messages. This is problematic for the average computer user because editing the Registry can render a Windows computer unusable. With a little guidance, however, you can fix Rundll errors safely.this solution 0f pc optimizer. i have been useing them for4 year now.
