Ultimate Malware Removal Guide -- Purge Your PC of Junk Files!
6. Advanced Registry Editing
If you happened to luck out and get a list of registry entries that were infected, then you can go through this more advanced step. This particular step is not required as long as the computer is mostly disinfected since the entries will only be remnant registry entries. When we do the final cleanup, it should also get rid of most of the entries. But if the entries are causing problems right now, then you can remove them here.
Launch the Registry Editor. You can do this by pressing the Windows Key and then pressing r simultaneously. Type regedit into the run window and press Enter.
You should get a list of five registry hives to the left of your screen. Each hive is similar to a pathway on your hard drive, such as C:\Program Files\Microsoft Office. In this example, you would double-click C, then double-click Program Files, and then find the Microsoft Office directory. The same process works in the registry editor. The only difference is you are not working with files and directories. You navigate through the left pane of the screen.
Navigate through the tree of entries until you find the exact one you are looking for. Make sure you select the right entry because many of them look similar. Then delete that entry from the left side of the window. Don't touch the right side, since that side just contains information related to that key. You may also use .reg files to do this, which may be simpler. If you are interested in this, see this Microsoft KB article.
7. Cleaning up the computer
Often-times malware removal leaves the computer with some junk files (.dat, .txt, etc) on the hard drive and some invalid registry entries which may produce errors. There are two programs you can run, CCleaner and Comodo Registry Cleaner. CCleaner will get rid of temporary files and Comodo Registry Cleaner will get rid of the registry entries.

8. Prevention and Concluding Advice
The ultimate goal of malware removal is to prevent it from re-occurring. By following simple steps you can help ensure that you won’t be infected again.
- Make sure Windows is up to date; otherwise you will get infected from the exploits that the patches are supposed to fix.
- Run security software. If you don’t, you will get a malware attack again. The software you run may not effectively clean the computer after you are infected, but it will stop you from getting infected in the first place.
- Run browser security software. Our favorite extension is WOT, this extension alerts you to risky websites. If you don’t want something like this, you can always use McAfee SiteAdvisor. It also warns you of risky websites, but does not block the malicious pages first.
- Remove your old versions of Java. The older versions of Java are heavily exploited by Vundo. When you install a new version of Java you are not removing the old version, it stays on your computer.
- Don’t pirate software. Software pirating is a big cause of malware. Many torrent sites secretly have malware downloads waiting for people to download.
- Don’t search for porn. Porn websites typically have malware on them since a lot of people browse these types of websites. Not all of them are infected, but if you browse around enough you will get infected.
