Increase your browsing speeds

You really don’t need to tweak your browser in case you are using Firefox because it is a browser which has been specially designed for optimized and fast browsing but if you can make it even a little more fast that would certainly be a treat for you. Likewise there is a trick to make Internet Explorer 6 fast too. Browsers are designed to work with fast connections but with this trick even dial-up users can experience fast and smooth browsing.

Optimize Firefox and IE Browsing Speed

I shall be teaching you two tricks which work separately on Firefox and Internet Explorer. It doesn’t require you to be some expert rather all you have to do is change some registry values and you are done. I have also included a video tutorial for those who want to see it step by step visually. This is perhaps one of the oldest tricks to optimize Firefox and IE but it still works great.

Trick to Increase Firefox Speed

1. Open firefox and in the address bar write about:config and press enter

2. Double click network.http.pipelining and set it to True

3. Double click network.http.pipelining.maxrequests and set value to 10 from 4

4. Right click and create a new string nglayout.initialpaint. delay and set its value to 0

You are done. Enjoy lightning fast Firefox browsing and now for IE.

Trick to Increase Internet Explorer Speed

1. Go to Start –> Run and type regedit

2. Select HKEY_CURRENT_USER –> Software –> Microsoft –> Windows –> Current Version –> Internet Settings

3. Increase the values (DECIMAL) from default to a higher value e.g. 10

 

 

For a few days in late January, the Netsky.p worm

I'm not saying that you should ignore such warnings. Copy the subject line or a snippet from the body of the e-mail and plug it into your favorite search engine to see if other It happens. It's nothing to be ashamed of. But chances are, either you're infected right now, as we speak, or you will be very soon.

For a few days in late January, the Netsky.p worm was infecting about 2,500 PCs a day. Meanwhile the MySQL bot infected approximately 100 systems a minute (albeit not necessarily desktop PCs). As David Perry, global director of education for security software provider Trend Micro, puts it, "an unprotected [Windows] computer will become owned by a bot within 14 minutes."

Today's viruses, worms, and so-called bots--which turn your PC into a zombie that does the hacker's bidding (such as mass-mailing spam)--aren't going to announce their presence. Real viruses aren't like the ones in Hollywood movies that melt down whole networks in seconds and destroy alien spacecraft. They operate in the background, quietly altering data, stealing private operations, or using your PC for their own illegal ends. This makes them hard to spot if you're not well protected.

Is Your PC "Owned?"

I should start by saying that not every system oddity is due to a virus, worm, or bot. Is your system slowing down? Is your hard drive filling up rapidly? Are programs crashing without warning? These symptoms are more likely caused by Windows, or badly written legitimate programs, rather than malware. After all, people who write malware want to hide their program's presence. People who write commercial software put icons all over your desktop. Who's going to work harder to go unnoticed?

Other indicators that may, in fact, indicate that there's nothing that you need to worry about, include:

* An automated e-mail telling you that you're sending out infected mail. E-mail viruses and worms typically come from faked addresses.

* A frantic note from a friend saying they've been infected, and therefore so have you. This is likely a hoax. It's especially suspicious if the note tells you the virus can't be detected but you can get rid of it by deleting one simple file. Don't be fooled--and don't delete that file.

people have received the same note. A security site may have already pegged it as a hoax.

Sniffing Out an Infection

There are signs that indicate that your PC is actually infected. A lot of network activity coming from your system (when you're not actually using Internet) can be a good indicator that something is amiss. A good software firewall, such as ZoneAlarm, will ask your permission before letting anything leave your PC, and will give you enough information to help you judge if the outgoing data is legitimate. By the way, the firewall that comes with Windows, even the improved version in XP Service Pack 2, lacks this capability.

To put a network status light in your system tray, follow these steps: In Windows XP, choose Start, Control Panel, Network Connections, right-click the network connection you want to monitor, choose Properties, check "Show icon in notification area when connected," and click OK.

If you're interested in being a PC detective, you can sniff and further for malware. By hitting Ctrl-Alt-Delete in Windows, you'll bring up the Task Manager, which will show you the various processes your system is running. Most, if not all, are legit, but if you see a file name that looks suspicious, type it into a search engine and find out what it is.

Want another place to look? In Windows XP, click Start, Run, type "services.msc" in the box, and press Enter. You'll see detailed descriptions of the services Windows is running. Something look weird? Check with your search engine.

Finally, you can do more detective work by selecting Start, Run, and typing "msconfig" in the box. With this tool you not only see the services running, but also the programs that your system is launching at startup. Again, check for anything weird.

If any of these tools won't run--or if your security software won't run--that in itself is a good sign your computer is infected. Some viruses intentionally disable such programs as a way to protect themselves.

 

Norton Disk Doctor and Caught A Virus

The drive doesn't spin. Either the onboard controller is bad or the motor is bad (assuming you did try the drive in another machine). It's time to hit the net and local independent shops to see if you can locate another drive of the same make and model that's good. Since the drive is probably an older drive and no longer in distribution, your best bet is to find an identical used drive. If you know someone with the same make and model, you might be wise to try and persuade them to sell you their drive with an offer of providing them with a free upgraded drive. If you can locate an identical drive, start with the controller replacement ... this is the simplest and least invasive. If swapping the controller doesn't produce the desire result, you can tear into the drive and swap the motors. While you have both drive opened up to accomplish this, scrutinize the platters, heads and armatures. You might even hook the drive up and power it from a system with both drives attached. This way, you could see anything that deviates between the actions of both drives when they are initialized. Swapping patters is unlikely to produce any positive result. They are a balanced system like the tires on your car and I suspect that the balance will be different for each drive as will other variables.

5. There's always Ontrack Corp. who will attempt to recoup your info starting at $500 and going up from there. They don't fix and return the drive either.

If the info is all that important to you, I would seek some professional and experience technician in your locality who makes his living from servicing and building computer systems ... not just selling them. If you have had much experience salvaging information from bad hard drives, your likelihood of success is low. In the case of soft corruption, all utilities have their eccentricities. Often times, Norton Disk Doctor will go too far (if you let it). It's wise to just let those utilities small steps and then have a look at the drive and see if you can copy it off. Norton will go so far as to rename directories and files, and even delete them or break them up into fragments which are useless.

4. Caught A Virus??????

If you've let your guard down--or even if you haven't--it can be hard to tell if your PC is infected. Here's what to do if you suspect the worst.

Heard this one before? You must run antivirus software and keep it up to date or else your PC will get infected, you'll lose all your data, and you'll incur the wrath of every e-mail buddy you unknowingly infect because of your carelessness.

You know they're right. Yet for one reason or another, you're not running antivirus software, or you are but it's not up to date. Maybe you turned off your virus scanner because it conflicted with another program. Maybe you got tired of upgrading after you bought Norton Antivirus 2001, 2002, and 2003. Or maybe your annual subscription of virus definitions recently expired, and you've put off renewing.

PC Maintance and Knowledge notes

The most common hardware problems are a bad controller, a bad drive motor, or a bad head mechanism.

1. Can the BIOS see and identify the hard drive correctly? If it can't, then the hard drives onboard controller is bad.

2. Does the drive spin and maintain a constant velocity? If it does, that's good news. The motor is functioning.

3. If the drive surges and dies, the most likely cause is a bad controller (assuming the drive is cool). A gate allowing the current to drive the motor may not be staying open. The drive needs a new controller.

4. Do you hear a lot of head clatter when the machine is turned on and initialized (but before the system attempts to access the hard drive). Head clatter would indicate that the spindle bearings are sloppy or worn badly. Maybe even lose and flopping around inside.

5. There is always the possibility that the controller you are using in the machine has gone south.

1. If the drive spins, try booting to the A> prompt, run Fdisk and check to see if Fdisk can see a partition on the hard drive. If Fdisk can see the partition, that means that it can access the drive and that the controller electronics are functioning correctly. If there is no head clatter, it may be just a matter of disk corruption which commonly occurs when a surge hits you machine and overwhelms the power supply voltage regulator. It commonly over whelms the system electronics allowing an EM pulse to wipe out the master boot record, file allocations table, and primary directory. Fdisk can fix the master boot record and Norton Disk Doctor can restore the FAT and Directory from the secondaries.

2. The drive spins but Fdisk can't see it. Try the drive in another system and repeat the test to confirm that Fdisk can't read through the drives onboard controller. If it sees it in another system, then your machines hard drive interface is bad. You can try an upgraded or replacemen controller card like a Promise or CMD Technologies (there are others) in you machine after disabling the integrated controller in the BIOS, but if the integrated controller went south, it may just be symptomatic of further failures and you'd be wise to replace the motherboard. Trying th drive in another machine also eliminates the variable that your machines 12 volt power output being bad.

3. If you get head clatter but a constant velocity on the drive motor (no surging), you might try sticking the hard drive in the freezer for about 12 hours. This is an old trick from back in the days of the MFM/ESDI driver era. This can cause the drive components to shrink enough to make the track marker align with the tracks. We don't see that kind of platter spindle wear much anymore, but back in the old days, the balancing and bearings weren't as good. Still, under the right circumstances, it might help. It would depend on how old the drive is and how many hours of wear have occurred. You have to be quick to get your info off the drive when it works. Back then, the drives were much smaller, so there wasn't so much to copy. So, go after the important data first.

Some PC Maintenance Tips and Tricks

1. How to Clone a Hard Drive

Did know that you could clone your current Hard Drive without having to by extra software? Maybe you didn't know that all that you needed, was already set up on your current system? Well, it is... and if you follow this tut, you shouldn't have much of a problem.

Make sure that you have a Master and a Slave setup on your system. The Slave drive, in this case, is where all the data on the Master is going to go to.

First: Perform a Scandisk your Master drive and follow that with a thorough Defrag. If you have an Antivirus program, do a thorough sweep with the AV first, then do the Scandisk, followed by the Defrag.

Second: Do the same thing to the target drive, as you did the Master: Scandisk then a thorough Defrag.

Third: Right-click on the Target drive and click on Format. When the box comes up, click your mouse onto the "Full" button.

Fourth: After Formatting the Target drive, run a Scandisk again and click on the button that says "Autofix Errors".

Fifth: In this final part, you might want to cut-and-paste to code in, unless you are sure that you can do it without making any mistakes:

Click on the "Start" button, then click on the "Run..." button, then place the following into the Runbox:

"XCOPY C:\*.*D:\ /c/h/e/k/r" (minus the quotes, of course) then press the "Enter" button.

If you receive an error message, then remove the space from between XCOPY and C:\

Anything that should happen to come up in the DOS box, just click "Y" for "Yes". When its all finished, pull the original Master from the system, designate the Slave as the Master (change your jumpers), then check your new Master out.

This tut has worked and has been tested on all systems except for Windows 2000, so you really shouldn't have any problems. If, by any chance, you should come across a snag, message me and I'll walk you through it.

2. Recover a Corrupted System File

If an essential Windows file gets whacked by a virus or otherwise corrupted, restore it from the Windows CD. Search the CD for the filename, replacing the last character with an underscore; for example, Notepad.ex_. If it's found, open a command prompt and enter the command EXPAND, followed by the full pathname of the file and of the desired destination: EXPAND D:\SETUP\NOTEPAD.EX_ C:\Windows\NOTEPAD.EXE. If either pathname contains any spaces, surround it with double quotes.

If the file isn't found, search on the unmodified filename. It will probably be inside a CAB file, which Win XP treats as a folder. Simply right-drag and copy the file to the desired location. In other Windows platforms, search for a file matching *.cab that contains the filename. When the search is done, open a command prompt and enter EXTRACT /L followed by the desired location, the full pathname of the CAB file, and the desired filename; for example: EXTRACT /L C:\Windows D:\I386\Driver.cab Notepad.exe. Again, if the destination or CAB file pathname contains spaces, surround it with double quotes.

3.Hard drive gone bad

The most common problems originate from corruption of the master boot record, FAT, or directory. Those are soft problems which can usually be taken care of with a combination of tools like Fdisk /mbr to refresh the master boot record followed by a reboot and Norton disk doctor or Spinneret.
