I have searched and I know that Avast and Eset are both reccomended, typically a bit more than other options here, for free and paid AV programs...but I haven't seen them compared much with Symantec AV Corp. So here's my situation. I can get a free copy of Symantec Anti-Virus Corporate edition from my work. I haven't seen too much talk about Symantec AV Corp. I hate Norton and wouldn't ever use norton. But the Corp anti-virus seems to work ok on my work pc without too much system performance degradation. So my question is...how good is Symantec Corp compared to other versions such as Eset and Avast? Should I use the Symantec Corp...or switch to Avast or Eset?? I am using Vista64 if that matters??
