Your system was found to have out-of-date or corrupted installations of either Norton, Trend Micro or McAfee Anti-Virus.  These programs are known for their poor performance. They use excessive amounts of memory compared to other alternatives slowing your computer down. They quite often are unable to remove viruses that are loaded into memory.  Why pay for these programs when there are free alternatives available that just work better? For these reasons we have removed these anti-virus programs and replaced them with free, better performing alternatives.
