I just bought the paid version of malwarebytes antimalware last night, and tried to run a full scan on my computer, which is a toshiba netbook205 with 160 GB and 2G ram running windows XP. When it reaches 20 min and 55 sec at file c:\Windows\Installer\2175188.msi, my system crashes -- to the point where I have to unplug and remove the battery to get the program to restart. It happens recurrently at this point. The quick scan runs fine, as does the quick scan from Norton, which came with the computer. How do I get past this problem? Thanks to anyone who can help. -- Scott
