So you don’t need JRE for javascript? That’s odd because I was midway through a book on Javascript a couple of months ago and to do the exercises I know I had to download either that or the SDK - and I’m pretty sure it was JRE.

Java is so popular because of being platform independent. I assume it’s still an interpreted rather than compiled language at least as far as web apps go so you’re always going to take a performance hit for that.

No, you don’t need the JRE for Javascript. All modern browsers support Javascript out of the box. They have since the Netscape days. It’s only called Javascript for marketing reasons, not because it’s actually related to Java. To quote Wikipedia:

The change of name from LiveScript to JavaScript roughly coincided with Netscape adding support for Java technology in its Netscape Navigator web browser. The final choice of name caused confusion, giving the impression that the language was a spin-off of the Java programming language, and the choice has been characterized by many as a marketing ploy by Netscape to give JavaScript the cachet of what was then the hot new web-programming language. [14] [15] It has also been claimed that the language’s name is the result of a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Sun’s Java runtime with their then-dominant browser.

I don’t know which book you read, but my experience is that many of them are poorly written. You don’t need an SDK for JavaScript (a text editor will do), though using one could certainly make the task easier. Maybe the book just wanted you to download JRE for the Eclipse IDE.

Java is platform independent, yes, but its implementation is inelegant in a very 90s way. For most modern web apps calling for platform-independence, AJAX is the norm (Javascript + real-time data transfer). This is what Google, Facebook, etc. use. More graphics-intensive things use Flash. And some classic websites (Craigslist and Wikipedia, for example) never bothered to make the jump and are stuck in the old fill-out-data-click-submit-wait-for-server-to-process-and-send-you-a-whole-new-page paradigm. None of them use Java on the user side (they may for stuff on the servers, hard to say).

Java is still used for a lot of things that computer geeks and scientists care about, but not typically for consumer web content anymore.

Firefox isn’t so much a memory hog as it is leaky. Pull up taskmanager after you have FF open with your standard number of tabs. Make a note of how much memory is being used. Then look at it several hours later after doing a lot of browsing with tabs being opened and closed all of the time. For me, it goes from around 250meg to over 1gig. Then I have to close it and restart. I don’t know why that is such a problem for Mozilla but it’s something they really need to work on.

Maybe so. I haven’t researched this enough so I won’t comment.

For the application manager error, paste this into a text file. Change the file name extension from .txt to .reg then double-click on it and answer yes:

Windows Registry Editor Version 5.00 
 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AppMgmt] 
"Start"=dword:00000004 

In HJT remove the lines that start with 02 and 012, restart, and try IE again.

ETA- rerun CCleaner befor restarting.

Worked!

Going back to PSI…

[yoyodyne]

Great! Your laptop specs aren’t too bad, you could run Windows 7 on it with 2GB RAM.

[Bearflag70]

PSI is clean!

All threats gone!

Threat Level Midnight is canceled!

Thank you!

Now set a new system restore point, and you are done.

Coming in a bit late to this thread, but does anybody run the System File Checker anymore? I run it by force of habit, but I have no idea if it actually fixes anything or not.

Oddly, my Windows Security Center Alert is showing Virus Protection is OFF.

However, MSE is showing real-time protection is ON with status as PROTECTED.

It 's probably part of Avast that didn’t get removed. Did you use Revo to uninstall it? In Control Panel, Administrative Tools, run Services. Do you see any names that start with “ash…”?

Try this and see what happens.

If that doesn’t work, in Services, stop Windows Management Instrumentation
Go to C:\Windows\system32\WBEM and delete the Repository folder
Restart Windows Management Instrumentation
Restart the computer

I used the normal add/remove function

[Bearflag70]

I’ll have to try the Avast removal later. Another lingering problem is slow WiFi. Videos load slowly and the connection is unstable at times. My other laptop does not have this problem working off the same modem and router.

[Bearflag70]

I should mention the problematic laptop sits under my desk, right by the modem, and the router is on top of my desk. The laptop is about 3 feet from the router. I use the problematic laptop as a desktop, with an external monitor, mouse, and keyboard.

Any reason you can’t run a wire to the router?

[Bearflag70]

I guess I could do that. I didn’t know that was an option.

Where’s “services” to turn off WMI?

As far as the CDROM, I don’t want to buy a new one if I can help it. I don’t know if it’s a hardware or software problem.
.

They are around $ 20 +/_ shipped on ebay. It’s usually a very simple removal - install.

Done! Simple and effective. Thanks.
