Even an Old PC Needs AV

I think it’s about time to revive my “Computer” category list. Not a new one but a renamed “Tech” category. Here I found a quite unique perception from my campus that an old PC, aged over six years, aren’t supposed to be installed AV (Anti-virus, not Adutl video) or any kind of security protection tools for some reasons

  • They’re too slow to run real time guard smoothly
  • Old PC contain no important data
  • Virus don’t want attack that kind of computer (wut?!)

I highlight the first one cause the rest are sound joking. That is, we need to find a good performance suite that requires small amount of bit cells. There’re so many out there but we choose free. There’re Avast, Avira, AVG, Comodo and Microsoft Essentials (for Windows). My choice is AVG which I’ll explain.

AVG has pretty simple interface which will help noob. It contains Anti-virus, Anti-spyware, Link scanner, E-mail scanner and Identity protection. The last one isn’t useful though. The update process is easy. I have already used it for half of year on a seven years old computer, without problem and smoothly. Will tell you how.

Let’s see, we need only a real time anti-virus so we can disable all unused features. “Unused” here can mean differently so feel free to disagree and take another action. I don’t need E-mail scanner because I always open them on web. I disabled it and nothing happened. That’s all? nope. It’s weird for an old PC to be connected with a 2GBps downspeed internet connection. I mean, what would you do? it even took more than 30 seconds to open Firefox. What I want suggest here is to break the slow down effect on internet connection (especially for dial-up) caused by this AVG suite. The culprit can be Link scanner which provide surf-shield. You can turn off it on same way as disabling feature before. As solution for this, you can use Firefox with NoScript extension. This extension protects you and saves your bandwidth. About background update we can skip this one. AVG won’t hide it and we can cancel the update if we want. Also update is very important. If you still feel some services sucking your speed, try following steps

  • Open your Device Manager, View -> Show hidden devices
  • Expand Non-plug & Play Drivers, you should see AVG Free Network Redirector
  • right click and disable it. Need restart.

Minor effect, you can go to its option and disable sounds, delete temporary update files and manage Resident Shield to only scan dangerous extension such as VBS and DLL.

With this, let’s hope your old machine can run an active AV as well as my machine. Cheer :)
