Part 3. Exercise
DONT BUY OR EVEN INSTALL A TRIAL OF THIS SOFTWARE UNTIL YOU READ THIS!!!I tried this program on a recommendation from the Microsoft web site, that should have been a warning right there. On install the etrust antivirus software (nothing else just antivirus) broke my Zone Alarm firewall, interrupted internet browsing and caused the system to hang up. I uninstalled it and have tried installing other antivirus programs since then but none of them will install; they keep popping up with guess what error message? That's right, please uninstall Etrust antivirus software, it is incompatible with our software. I've emailed Etrust and tried thier 'live' online chat and get no response. The software is evil, it looks like I will have to format my hard drive to get rid of it. I can find no related keys in the registry to clean by hand. Don't repeat my mistake!!!
Answer:
Negative
