Avgcsrvx.exe – Hogging CPU resources during scan

This is a common problem. Avgcsrvx.exe is known to use up to 50%-100% CPU resources when the AVG Antivirus program is running a virus scan on your PC.

To tackle this issue, it is wise to schedule virus scans on your PC at a time when you do not need to use your computer. For instance, you can schedule virus scans late at night, say 1:00 AM.

  • Get rid of temporary files – Use the built-in Disk Cleanup utility to delete temporary and other unused files from your hard disk.
  • Run a registry scan – Perform regular registry scans to remove invalid, obsolete, and incorrect entries from the registry. You may use a reliable and advanced registry cleaning tool, such as PC Health Boost for this purpose.

  • Defrag the hard disk – After you have deleted the temporary files and run the chkdsk command, run the built-in Disk Defragmenter utility to defragment your hard drives.
