I want a heavy antivirus.
Modern Computer Threats
Today's computers are under constant attack from threats of all types including:
- Computer viruses
- Phishing email scams
- Phony "security" software
- And more
Collectively, these threats are called "malware." In the past, computer viruses arrived on computers via email attachments that activated when opened or from computer disks that had been infected. While these transmission types are still common, malware now sneaks onto computers in many different ways. For example, "driveby downloads" occur simply by landing on a webpage that has malicious code on it. All you have to do is visit that webpage and without your knowledge, a computer virus or some other malicious program silently installs on your computer. If this malware is what's known as a "downloading Trojan," then the Trojan will continue inviting new malicious programs onto your computer, downloading even more malware - all without your knowledge.
The Effects of Malware
When this happens, not only does your computer have unwanted programs on it, these programs carry out evil deeds. They may turn your computer into a robot that is controlled by a remote hacker who uses it to send spam or attack other computer networks. Keyloggers record all of your keystrokes and send files to hackers and identity thieves who mine the files for credit card information. And, because all of these programs are running simultaneously (and poorly written), they use up your computer's resources such as memory, bandwidth, and hard disk space resulting in a slow computer.
Powerful Antivirus Solutions
With so many threats out there, and the risk of having your personal financial information compromised, a powerful antivirus/antimalware solution is in order. Look for an updated product from a reputable company and be careful of imposters. Imposters take advantage of misspellings and common name configurations to trick users into thinking that they are dealing with the legitimate program. While there are some good free programs out there, the freebies often have limitations. For example, some free programs require that you manually update the software or run scans on demand while commercial programs automatically update the software as soon as new malware is discovered and provide real time protection.
It's been a while since we've reviewed antivirus/antimalware programs; however, check out the antivirus developers listed here and consider their 2010/2011 editions as each developer is highly reputable and known for developing powerful antivirus solutions.
