Hi, and thanks for taking the time to look at this for me. I've been experiencing slow performance as of late, and my boyfriend is training here. He took a look, but was not confident in carying out any fixes and advised me to come and seek help here. He's already removed AVG using the AVG uninstaller, done a clean with CCleaner, and installed Avast. Avast has done a boot time scan, but did not find anything. He says there is remanants of an old Norton install that should be cleaned out, and theres some entries in the HijackThis log he's not sure about. We also have a problem with firefox still looking for the AVG toolbar, but not finding it. its currently disabled in the add-ons section, but the uninstall button is greyed out. I had P2P software on this laptop a while ago, but since uninstalled it, so its ok to remove any further signs of P2P if found. Obviously, the Laptop is an Acer, Runs Vista 32bit and has service pack 1. Logfile of Trend Micro HijackThis v2.0.2 Scan saved at 22:0
