Windows Scan is a rogue defragmenter utility, which claims to be capable of optimizing your system but is actually out to steal your money. Windows Scan is the same rogue application as all of these following fake programs: Defragger, Memory Optimizer, Disk Helper, Disk Optimizer, Good Memory, HDD OK, Quick Defrag, FullScan, Scanner, Disk Repair, Smart HDD, HDD Rescue, HDD Scan, Win Defrag, Win HDD, Check Disk, ScanDisk and System Defragmenter. This list only represents about four months of activity! The group of scam artists behind the Windows Scan fraud is trying to evade detection and keep infecting computers by constantly changing the name of their malware. This family of rogue defragmenter applications has been going through various names since October 2010, and Windows Scan is a name that began being used around the third week of January 2011. It's all one giant scam.

How Windows Scan Infects a Computer

Since the people behind the Windows Scan scam stand to make a huge profit on it, they have "marketed" this malware in a few different ways online. That means that you can wind up with Windows Scan sneaking onto your computer in any of several different manners. Windows Scan can be part of a fake online free system scan, which actually infects your computer with Windows Scan. Another mode of infection is that a Trojan Horse that will later deliver Windows Scan is hidden in a file that you download; or you download a file that contains a hijacker hidden in it, which causes your browser to redirect you constantly to the malicious website for Windows Scan. In other words, if the people behind Windows Scan cannot get you to put it on your computer on your own, then one way or another, these crooks will sneak a virus onto your computer that will take care of that part.

What an Infection with Windows Scan Looks Like

Once Windows Scan is on your computer, it works to convince you that your computer has some major problems and that you have to buy Windows Scan in order to fix them. In order to achieve this desired effect, Windows Scan does a few different things. The most common thing (and most universal to rogue utility programs) that it does is to generate fake system scans and scan results, and create fake warning messages. Windows Scan will configure itself to show its bogus home screen and run a fake "scan" when you start Windows. The results it comes back with are meant to scare you, and they will include claims that the CPU temperature is too high, that your hard drive has bad sectors, that the hard drive cannot  be found, that there is damaged data on your hard drive, that you are critically low on RAM, etc.

The home screen also has a phony defragmenting tool, which is all for show. If you try to use this tool, Windows Scan will tell you it needs to run the defragmenter in Safe Mode, and then it will fake going to safe mode and show a little progress animation without actually doing anything else. This fake tool only exists to give Windows Scan another opportunity to tell you that it has found very scary things wrong with your hard disk. Do not believe a single thing it tells you. You can ignore the things that Windows Scan says about your other programs too, since it will prevent you from opening anything else and tell you that the reason for it is that the program could not be found, or there was an error reading the hard drive. All of this is nonsense.

In order to increase its appearance of legitimacy, Windows Scan will create pop-up warnings from the system tray, and these can become pretty frequent. These warnings, along with all of the other warnings, will say you need to pay for and download the Advanced Module in order to fix the problems it has found, or it will recommend that you download "the following sertified software". (Notice the spelling error, a dead giveaway that Windows Scan is not legitimate.)

Just in case you do not believe that anything is wrong with your computer, Windows Scan will make it look like something is really wrong. Windows Scan is reportedly capable of making it appear as if some of your folders are empty, and showing the contents of the wrong folder when you try to look at others. In particular, Windows Scan can make it look like System32 is empty, and that would be very scary if it were real. On top of all of this, Windows Scan can eat up system resources with all of its activity, which can cause your PC to be slow or unstable. No matter what things may look like when Windows Scan is doing its dirty work, you cannot consider anything reliable if Windows Scan could possibly have had a hand in it.

Always remember, paying money to the con artists who have wasted your time and caused you so much frustration is never the solution. Paying that money is unnecessary and does not change a thing. You may potentially be able to disable some portions of Windows Scan entering the number 0973467457475070215340537432225 into Windows Scan's security key field – but be warned that this does not remove the threat; it only temporarily shuts it up. Do not leave Windows Scan on your computer, because it is only ever capable of being malicious.

Method of Infection

There are many ways your computer could get infected with WindowsScan. WindowsScan can come bundled with shareware or other downloadable software.

Another method of distributing WindowsScan involves tricking you by displaying deceptive pop-up ads that may appear as regular Windows notifications with links which look like buttons reading Yes and No. No matter which "button" that you click on, a download starts, installing WindowsScan on your system. WindowsScan installs on your computer through a trojan and may infect your system without your knowledge or consent.

If you think you may already be infected with WindowsScan, use this SpyHunter Spyware dectection tool to detect WindowsScan and other common Spyware infections. After detection of WindowsScan, the next advised step is to remove WindowsScan with the purchase of the SpyHunter Spyware removal tool.


WindowsScan may attempt to change your computer's desktop, hijack your browser, monitor your Internet browsing activities, change system files, and can do this without your knowledge or permission. Therefore, it is strongly recommended to remove all traces of WindowsScan from your computer.

Remedies and Prevention

WindowsScan, as well as other Spyware, are constantly evolving and becoming more advanced to avoid detection. WindowsScan along with its variants can install in different locations and even when you try to uninstall it you find they reappear when you reboot your computer.

Install a good anti-spyware software

When there's a large number of traces of Spyware, for example WindowsScan, that have infected a computer, the only remedy may be to automatically run a Spyware scan from a good anti-spyware software designed to detect WindowsScan and other types of spyware.
