Hi, First of all thanku Alwil for providing a free AV.
AMD Sempron, WinXP MCE, Office 2003, Nero 6.6, No Firewall.
I was using McAfee 2007 Internet Security Suite but it was eating up resources badly (but no other problems), so thought of switching to Avast, but after installing the latest one from the Alwil site, the Explorer quit responding whn i attempted to create a new folder in the hdd as usual (non-system drive, i think e: or f:), had to restart comp, cud not close thru taskmanager, same happnd with yahoo messenger (no changes made to yahoo), was able to login but it froze the moment i clicked anywhere on it, everything was fine after i uninstalled it, i tried installing another one that i downloaded a month back from this site which resulted in the same problem, have to restart comp to get back to normal, now i dont it installed and everything is running fine. Plz advice.
