I use AVG Antispyware (free version) and a few weeks ago I could run a full scan in about 15 minutes. Now it takes just over 48 minutes to run the same scan. I have added nothing into my hard drive in weeks. I also ran the DEFRAG yesterday but cancelled it after 5 hours. Can someone help.


Does AVG hang up on some file(s), or you can see it running?
Try defrag in Safe Mode, first? Do you run built-in Vista defrag?The defrag needs to run to completion for it to help.
Try running it overnite while you are sleeping.
Turn off any unneccessary programs in the system tray.Broni,
Yes I run the built in Vista defrag. I did not know any other way. When it is running it does not stop but RUNS through to completion.

However I will try what you and Patio suggest
