ESET Internet security software and antivirus software works great.  ESET antivirus uses advanced heuristic technologies and updates automatically to protect you from the latest threats.  Now I’m not an expert on internet security software or antivirus software but I am a user of Norton and McAfee for years and years.  They all update and seem to claim the latest updates and they probably all do it pretty well.  I switched to ESET because it is ranked very high or on top all over the Internet from some very reputable software and antivirus review sites.  Not only is it ranked high, users of ESET claim that it runs well.  This is the problem that I have always had with Norton Antivirus and McAfee.  They both like to kill your system and I can notice a noticeable slowing, along with other compatibility problems.  ESET seems to be lighter and run more efficient.  So far I have had no problems with speed and compatibility with ESET.  ESET works great, so if your looking for antivirus software or looking for change give ESET a try.  If your doing more then one computer you can save with ESET coupon for multiple licenses.
