CCleaner deleting scan history of Anti-Virus program

I am using CCleaner v2.22.968 in my computer with Windows Vista Home Premium 64-bit SP2.

I have AVG 8.5 Anti-Virus. When I use the CCleaner, all the Scan History of my Anti-Virus software is deleted and the Statistics shows under Last Scan: Not Yet Scan. So I am loosing important data regarding the scans already made.

Anyone knows how to avoid this issue?
