Dr Bill’s Prescription for a Slowing Computer

clip_image002

Check Add/Remove Programs and Remove all programs that you do not use.

Keep your computer running lean, keeping only the applications that you actually use. Also look for programs that were not intentionally installed, and applications that do not uninstall properly.

  • Process:
  • Start
  • Control Panel
  • Add/Remove Programs

Check for Spyware and Viruses

Check your antivirus program to make sure that it is getting updates, and that your computer is getting scanned occasionally. Run Spybot Search and Destroy, Lavasoft Ad-aware, making sure you update them first before scanning (see Dr Bill’s Prescription for Spyware and Viruses) If you have persistent recurring adware or viruses, seek the help of a professional.

Clear off desktop

Keep your desktop clear of files and folders. Keep only shortcuts on your desktop. Use the same logic with your email inbox. Try to keep the inbox clean, leaving only action items, and saving the rest in appropriate files, that are not in you inbox.(See Dr Bill’s Prescription for an Overflowing Inbox).

The logic behind this is that when your operating system boots up, it needs to load all those files. When the email is opened, it needs to index all the emails that are in the inbox for display.

Run Disk Cleanup

Process:

  • Start
  • Programs
  • Accessories
  • System Tools
  • Disk Cleanup This will scan for a little while (the longer it has been, the longer it will take). The items that it will display vary, but usually include
  • Downloaded Program Files
  • Temporary Internet Files
  • Office Setup Files
  • Recycle Bin
  • Temporary Files
  • Compress Old Files I would check all but the Office Setup Files. The Compress Old Files option is not usually on by default, but should be. This takes old files that are rarely accessed, and compresses them, much like a zip file does. This saves space on your hard drive, and followed up with a Defrag, can really boost your disk performance.

Run Disk Defrag

Process:

  • Start
  • Programs
  • Accessories
  • System Tools
  • Disk Defragment

This will start a long process that places related files and bits next to each other, reducing hard disk “thrashing” (searching back and forth for files). I also moves files closer to the center of the disk, the left of the progress display. The closer to the center, the faster the access will be.

The ideal, never reached of course, is all the bars to the left, all blue or green, no spaces.

Repeat Steps 4 and 5 daily, until speed has cleared up.

If you are obsessive, you can do it several times a day.

If you are forgetful, you can set it up to run automatically with task scheduler.

Step 6 (optional)

CCleaner (Crap Cleaner, use slim edition) is a program that scrubs your registry for things it doesn’t need, and really cleans out old temporary files that Window seems to want to hold on to forever. There may be some risk, but if you only use the default options you should be safe. I have never had any issues.

Keep Your Computer Running Well

Microsoft/Windows Updates

You’ve seen it there in your program files. If you have updated to at least windows XP, you have probably been prompted to setup up automatic updates. That’s a good thing. If not, run them. If you can’t find it, use internet explorer to go to microsoft update. Don’t worry about optional updates.

Antivirus

I recommend Avira (free) to anyone who needs excellent antivirus protection, or I recommend ClamWin (free, open source) for older, slower computers or lower risk computers. I use ClamWin because I put a premium on the performance, and am willing to take the risk on a product that doesn’t protect as well.

[Edit: 2011] Use Microft Security Essentials

Spyware/Malware

I use Windows Defender to prevent spyware. Once you have used Spybot Search and Destroy and Lavasoft to clean up spyware, remove them, and make sure Windows Defender is installed and running.

Cleanup Virus Trojan

There is a spyware program that is very common right now, that tells you have multiple viruses, and want you to buy their software to get rid of it. Here’s the cleanup for that.

Word 2007 "File Name is not Available"

Weird problem of the week - A friend could not open the Word 2007 Documents she saved.
Software: Word 2007, Vista, AVG.

Turns out, AVG was the culprit. I removed AVG, and installed my favorite Open Source AV ClamWin, and while I was doing that, looked up the issue on Google and found this:

This person was running AVG anti-virus. We uninstalled AVG and full file access was restored after a reboot. I have not researched this to determine if it's from a recent AVG update or if it's an inherent problem between AVG's engine and Word '07. Bottom line was that uninstalling gave her back her files.
Reference: http://answers.yahoo.com/question/index?qid=20080903014217AAVP4pU

Sure enough, rebooting after the AVG uninstall, the documents opened fine.

Did not find evidence of this issue on AVG's site.


**Just a reminder to those using AVG Free, the license is for personal use only, no business or charitable orgs.

Avira Antivirus

I found another free Antivirus software, Avira Personal, available for Linux and Windows, recommended by Consumer Reports and CNET.

As with the AVG Free product, it works well with Windows, but the license is personal only and excludes charitable org use.

AVG Antivirus vs. ClamWin


I have been using ClamWin now for a year or so. I liked the fact that it has a smaller footprint.

I was getting ready to try AVG Free again, when I noticed in the license that it was only free for personal use, and specifically excluded non-profit businesses from the license.

I get excluding business, but why Non-Profits? Just feeling uncharitable?
ClamWin is a Sourceforge open source project.

Anyway, no infections using ClamWin, so I continue on.

In addition, I use:
Windows Firewall (installed by default on XP and up)
Windows Defender
Firefox and Chrome


(Kim Kommando has her own set of recommendations for free security software)

Links:
ClamWin
AVG Free

[UPDATE: 2011-12]
On all but the lowest powered machines, I now install Microsoft's own Security Essentials .  I find that it generally does not impede performance, as I find with many other av software, and so far has been smooth.
