Spyware Scanners

Free Spyware Tools

Disclaimer: I did not write any of the tools listed here. They are all available free of charge on the Internet but I have included them here for your convenience.

MalewareBytes AntiMalware
Malware is any kind of bad and unwanted program. MalwareBytes removes it. It does a very good job of it. It runs very fast. A quick scan only takes about 10 mins and gets almost all of the spyware and viruses. The free version does everything the full version does except real time scanning. Running this in safe mode will remove 95% of the viruses on a given computer.

One fo the best one time scan programs. If Malwarebytes cannot find or remove a virus or spyware ComboFix most likely will be able to. It uses very sophistcated techniques to remove malware including using the recovery console which allows the computer to boot into a mode where even the most advanced root kits will not work. It’s very easy to use and has a very helpful guide. It says it can cause problems with legitimate programs but I have never had a problem.


Probably the most powerful free spyware tool I have ever used. It scans the windows registry for any possible spyware risks and reports them all. You have to be careful it reports both the spyware and legitimate programs that start up. As well as running processes. Works with Windows XP/2000/Me/98/95/NT


Fixes the things HiJackThis can’t fix. LSP is related to windows ip stack and sometimes spyware adds its own entries into this so that windows ip stack gets cluttered with flagrent LSP entries. newdotnet is a good example of spyware that does this. If you are having trouble accessing the Internet after removing spyware you need to run this tool.

Security Essentials

One of the best the best spyware scanner and remover I have ever used. It is free but still in beta and surprise, Microsoft didn’t actually make it but purchased it from Giant Software. It is easy to use, automatically updates and automatically scans. It is good at detecting spyware that tries to install itself. The number of pop-ups and security warnings it displays can be annoying and confusing to new users but it is a very good program. Windows Defender is the newer version but has the disadvantage of only running on windows xp sp2, and it can be a pain to install because windows has to be validated which is hard to do if spyware is keeping Internet explorer from working.

AVG Free Virus Scanner
AVG is a free virus scanner for personal use. It the best Virus scanner I have ever used. It is fast, it does not have the bloat that Norton and McAfee have. It can detect viruses on the fly and remove them. It automatically updates, checks for viruses in realtime and can do scheduled scans. I usually install this program and it runs while I do a spyware scan with a different program and AVG will find viruses while the other scanner scans your hard drive. Works in Windows 98/Me/2000/XP.

Spybot Search and Destroy

Spybot is a good scanner when you can’t install Microsoft Antispyware. It can even get rid of things that Microsoft’s scanner can’t. It also has many features that help prevent spyware from being installed. Its greatest strength is that it works on all versions of windows, even 9X.

Clam Anti-virus

Clam Anti-virus is a GPL virus scanner. It does a better job of detecting viruses than AVG and its database is updated more regularly. Unfortunately, it can just detect and report viruses. It is up to you to remove the Virus. It is useful for scanning downloaded files and viruses before you run them. It runs in Windows as well as *nix. It is more commonly used by servers to filter mail that contains viruses.
