I've been using Avast since I've installed my machine. I have not used any other antivirus programs.
This latest update, required to update my avast has delayed my program launching ability and folder viewing.
Computer:
AMD Phenom X4 9600BE
4GB of DDR2 (4-4-4-15)
640GB WD SATA2 (Dual 320GB Platters)
BFGtech 8800GTS 512MB OC2
Windows Vista Ultimate 64BIT SP1
Avast 4.8
The test....
Loading explorer with Avast 4.8 off.
Windows pop right open, no delay, no circle spinning, no program delays.
Loading explorer with Avast 4.8 on.
3-4 second delay on loading file explorer, programs have longer delays.
Turning off executable scanning and scan folder when launching helped remove the delay.
Anyone notice this? Resolution to this issue? Its gotten progressively worse after these updates.
