well avast FTW!!! KUZ if ur looking for a pirated one (one dat uses a keygen) avast never gets blacklisted keys but on kaspersky they alwayz get blacklisted because kaspersky uses a different type of keys nd everyone uses the same ones so the get blacklisted, also although kaspersky covers all most every virus it takes alot of memory on ur computer causing it to go slower nd avast does not but avast does not cover malware but idc kuz if i get malware i use malwarebytes anti malware (works like a charm) plus avast is easy to understand nd simple to use.
