Defragmentation is an old and well-known PC maintenance method that helps to prolong harddisk lifespan. It achieves so by moving data bits that spread across the disk closer together and making the used space more compact. As a result the harddisk spindle moves less above the disk when seeking the data you want, therefore head scratch is less frequent - HDD lifespan increases. In some cases, it also helps to consolidate some free space, because if the disk is fragmented and getting full, it is difficult to save a large file on it.

Recently we came across reports saying that defrag could improve system performance as well. For example, MyDefrag claims to be a disk defragmenter as well as optimizer (a maintenance utility to make your harddisk faster). If it is true, it is amazing because we have a new way to speed up our computers. We are skeptical because work applications rarely use file I/O compared to other operations like memory and page file access. It is easy to understand this because you save your work or load another file only once in a while. Memory read is incredibly fast, and page file access is not improved by defragmentation because page file is usually fixed in size or does not get fragmented so easily.

So, one day you decided to cut the cable and start using wireless connection instead of your old cable connection but as usual, new technologies come with new problems. When you are connected via wireless connection you may happen to run into disconnections so here you are, some tips.

The first thing is… why are you using a wireless connection? If you are just using it because you can use it, it is better for you not to do it anymore. Wireless connections are only useful if you have to put a long wire from the modem / router and you want to save that installation, but if you have the computer next to the router and you use wireless you are not making the most of your internet connection. If you can put a cable, forget the waves. Wireless connections are more unstable and less safe than a cable connection no matter how well do you protect them so, if there is a choice, use cable instead of wireless.

One day we open our computer and see a warning message from Windows saying that our hard disk space is running out. We do some cleanup by emptying the recycle bin, but the free space remaining in C drive is still low and we cannot defragment it as a result. Problem like this is likely to happen and recur. If you have no idea what is eating up the hard disk space and you haven't been keeping too much personal files or installed many programs, it will be a puzzling and annoying problem. This guide shows how to trouble-shoot such problem and is applicable to Windows XP and Vista.

Some virus or malware could shut down or disable antivirus software or service, block internet access to certain security sites such as Windows Updates and antivirus download sites, or somehow refused to be deleted because the system reported that a file was being accessed.

To work around this problem. You can boot into Safe Mode with Networking to remove them.

Restart computer -> after the first screen, press F5 or F8 -> A menu will show up -> Choose "Safe Mode with Networking" -> Choose an account with administrator access -> Click OK in the next prompt asking whether you want to continue in Safe Mode.

In this Safe Mode, you are still connected to your network or still have wireless access, but all other startup programs are bypassed, possibly including the virus and malware. Only the most persistent virus and malware could get into Safe Mode. When they are no longer functioning, cleaning them will be easy.

Once you are inside the Safe Mode. You can open your browser and search for "antivirus" and "anti-malware" in Google, download and install a decent antivirus software (if you do not have one), and a malware removal software such as Malwarebytes' Anti-Malware, and then, just do a full scan with the software. After you have removed the virus and malware, remember to update your Windows on restart.
