I have a Toshiba Satillite Laptop and Windows Vista OS . My windows explorer keeps crashing like every couple of minutes. I have Avast antivirus, and I have Malware bytes on it so if those are doing their jobs I do not believe I have any viruses. What else could it be. I had my laptop gone over and fixed last fall so this is a new thing and really irritating because I have to keep restarting my windows explorer and am unable to do anything in the explorer, like look at my files etc. Please help. Thank you. Forgive me if I posted this on the wrong forum, I wasnt sure where it belonged.
