I bought NEW Sony Vaio Laptop and installed ZA and installed ZA anti-virus 7.1.078 for Vista. Had nothing but BSOD's with varying errors since. Here's how I fixed it. While ZA install disabled the Windows Firewall in Services it was still checked and Started Automatically when Vista booted. In other words it still showed as disabled if you went into the Control Panel but the service was still running. I unchecked the Windows Firewall service and changed the Startup to disabled and have had no more issues.
Operating System:Windows Vista Home Premium
