HijackThis, sometimes abbreviated HJT, is a freeware spyware-removal tool for Microsoft Windows originally created by Merijn Bellekom, and later sold to Trend Micro. The program is notable for taking a heuristic approach to detecting malware - rather than relying on a database of known spyware, it scans a user's computer quickly, creates a list of differences from a known spyware-free environment and allows the user to decide what from the list is to be removed. HijackThis is used primarily for diagnosis of spyware, as uninformed use of its removal facilities can cause significant software damage to a computer.
HijackThis can generate a plain text logfile detailing all entries it finds, and most entries can be removed or disabled by HijackThis. Inexperienced users are often advised to exercise caution, or to seek help when using the latter option,[1] as HijackThis does not discriminate between legitimate and unwanted items, with the exception of a small whitelist of legitimate entries — thus allowing a user unintentionally to prevent important programs from operating, which may cause their system or its peripherals to stop working. HijackThis will, however, attempt to create backups of the files and registry entries it removes, which can be used to restore the system in the event of a mistake.
A common use is to post the logfile to a forum where more experienced users can help decipher which entries need to be removed. Automated tools also exist that analyze saved logs and attempt to provide recommendations to the user, or to clean entries automatically.
Use of such tools, however, is generally discouraged by those who specialize in manually dealing with HijackThis logs: they consider the tools to be potentially dangerous for inexperienced users, and neither accurate nor reliable enough to substitute for consulting with a trained human analyst.
Later versions of HijackThis include additional tools like a task manager, hosts file editor and alternate data stream scanner.

Delete programs you never use
Many PC manufacturers pack their new computers with programs you didn’t order and might not want. These often include trial editions and limited edition versions of programs that software companies hope you will try, find useful, and then pay to upgrade to full versions or newer versions. If you decide you don’t want them, keeping the software on your computer might slow it down by using precious memory, disk space, and processing power.
It’s a good idea to uninstall all the programs you don’t plan to use. This should include both manufacturer-installed software and software you installed yourself but don’t want anymore—especially utility programs designed to help manage and tune your computer’s hardware and software. Utility programs such as virus scanners, disk cleaners, and backup tools often run automatically at startup, quietly chugging along in the background where you can’t see them. Many people have no idea they are even running.
Even if your PC is older, it might contain manufacturer-installed programs that you never noticed or have since forgotten about. It’s never too late to remove these and get rid of the clutter and wasted system resources. Maybe you thought you might use the software someday, but never did. Uninstall it and see if your PC runs faster.

How to defragment your hard drive
Fragmentation makes your hard disk do extra work that can slow down your computer. Disk Defragmenter rearranges fragmented data so your hard disk can work more efficiently. Disk Defragmenter runs on a schedule, but you can also defragment your hard disk manually.
1. Open Disk Defragmenter by clicking the Start button , clicking All Programs, clicking Accessories, clicking System Tools, and then clicking Disk Defragmenter. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
2. Click Defragment Now.
Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.

How to turn off visual effects for better performance
If Windows is running slowly, you can speed it up by disabling some of its visual effects. It comes down to appearance versus performance. Would you rather have Windows run faster or look prettier? If your PC is fast enough, you don’t have to make this tradeoff, but if your computer is just barely powerful enough for Windows Vista, it can be useful to scale back on the visual bells and whistles.
You can choose which visual effects to turn off, one by one, or you can let Windows choose a bunch for you. There are 20 visual effects you can control, such as the transparent glass look, the way menus open or close, and whether shadows are displayed.

To adjust all visual effects for best performance:
1. Open Performance Information and Tools by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Performance Information and Tools.
2. Click Adjust visual effects. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click the Visual Effects tab, click Adjust for best performance, and then click OK. (For a less drastic option, select Let Windows choose what’s best for my computer.)
