I'm using a Toshiba Satellite A15-S127 laptop running Windows XP SP3 fully updated. I'm also running Avira Antivir Personal ver 184.108.40.2060 and Spyware Terminator ver 220.127.116.117. I was having serious problems with long startups, strange mouse responses, and occasional long pauses in activity with IE 7.0 and other software and a helpful person from this forum suggested I do a clean uninstall and reinstall. Before reinstalling should I turn off Avira and Spyware Terminator, uninstall them too, or just install Zone Alarm Pro with them running? Is there anything else I should do while reinstalling? Any suggestions on how I can avoid the strange problems I've been having will be very much appreciated. Thanks.
