I have been trying several of these Antivirus products for several years, of which includes Norton Antivirus, Trend Micro PC-Cillin, McAfee and CA's EZArmor.
Of all, I recommend Trend Micro as the best of the best, due to the following reasons:
- Powerful Firewall with easy user configuraton to block Virus, Trojans, Attacks etc.
- Real-time scan and activates emergency locking when detects a virus intrusion. The real-time scan is far beyond comparable to other Antivirus.
- A software suite with all round protection: Firewall, Antivirus, Spyware, Malware, Internet Security etc. User do not have to purchase multiple licenses or software to get what they need. It is all in one easy package.
- Powerful virus detection that none other can compare. So far it detects more than 5 viruses that cannot be found in the virus encyclopedia on the Internet. Not even other antivirus knew of these viruses.
- Affordable. Although the subscription and software package is a little more expensive as compared to Norton and CA, but it is overall in the acceptable range.
- Prompt and fast service support. Email to them today and you get your answer latest tomorrow.
- I still can continue with my work even with PC scanning running. And the scanning is thorough and fast.
Worst Antivirus:
- Norton Antivirus will stay on top of this list... forever.
- Unable to detect viruses that exist one month ago even though performed Live Update (latest copy).
- Internet Security does not block all attacks. I remember my computer got attacked even with the Internet Security enabled!
- Support really is bad. Why? Because they simply do not respond, not even to complaints.
- Even until now, only Trend Micro has information of a particular worm: WORM_SDBOT.YB. Don't believe it? Search the worm name in google.
- Scanning is like a tortoise crawling which may take about 20 - 30 minutes. I can take a meal, come back and the system is still scanning. (NO KIDDING!)
- I guess for Norton Antivirus to crawl away from the worst Antivirus title, they need to improve on their attitude which includes service, support, troubleshooting and performance. None of these got a pass grade for Norton Antivirus.
