while offline avast antivirus told me that i had was infected at win32wintool [trj] and to send it to a "chest." my xp professional is running VERY slow and if i do 2 simple tasks it "stops responding." aol told me that installing 9.0 security edition will fix the computer (does this sound right??) but i must first uninstall all anti virus programs which i did except for the the pc cillin which came with this computer. when i try, i am told that "windows installer could not be accessed" because it is either in safe mode (NOT!) or not installed correctly. i do not know how to fix it and get rid of pc cillin. any help would be appreciated. thanks.
