I have been having issues with my Dell XPS 15 crashing when I have Vipre Antivirus open. I attempted to change the settings on my vipre program a couple of weeks ago and the computer screen freezed. I was forced to reboot my computer b/c I was not able to get out of this program with CTRL-ALT-Delete. I thought I might have malware on my computer so, I downloaded Malwarebytes and booted my computer in Safe Mode with Networking and Malwarebytes did not find anything wrong. I checked to see whether I updated everything, and all the updates for Windows, Adobe, etc... have been done. I had Dell check my hardware on my computer and everything passed. Therefore, I tried troubleshooting the problem with Microsoft and they no solutions for this problem.? I have noticed strange things happening to my computer. For instance, I loose my network connection periodically or certain programs have disappeared in my start menu ? Also, my computer has been slow at times when I am scanning with vipre. Can you help me ?
