There are a few optionals that you can fix depending on your needs. They use some resources and may not be needed at Startup. Fixing them here will not prevent you from opening them manually as needed.
If you want to fix them, open HijackThis and run a scan. (No need to save the log unless you intend to post it back here.)
Place a checkmark next to the ones you would like to fix:
O4 - HKLM\..\Run: [SunJavaUpdateSched] \"C:\Program Files\Java\jre1.6.0_02\bin\jusched.exe\" Sun Java update scheduler. Checks for updates. Not necessary. Removing this entry will free up a small amount of system resources.
O4 - HKLM\..\Run: [CTxfiHlp] CTXFIHLP.EXE Soundblaster X-Fi card related. This particular process provides the help functionality for your card. It is not necessary, however, if you do not have a Creative Lans X-Fi card or a similar sound card by Creative Labs, then this file might be spyware, attemtping to masquerade as the Creative Labs software.
O4 - HKLM\..\Run: [UpdReg] C:\WINDOWS\UpdReg.EXE A small program that reminds you to register your Creative Labs product (i.e. sound card, video card). Unnecessary. Removing this will free up a small amount of system resources.
O4 - Global Startup: Adobe Gamma (Calibrate monitor).lnk = C:\Program Files\Common Files\Adobe\Calibration\Adobe Gamma Loader.exe Adjusts monitor colours across all programs, including Photoshop. It is needed by some graphics professionals who want their monitor calibrated. Most home users will not need it, and thus should remove this entry.
Close all windows except HijackThis and click "Fix Checked". Close HijackThis and reboot.
That should do it.
Here is my standard list of simple steps that you can take to reduce the chance of infection in the future.
You may have already taken some of these steps: 1. Visit Windows Update: Make sure that you have all the Critical Updates recommended for your operating system and IE. The first defense against infection is a properly patched OS. Windows Update: http://v4.windowsupdate.microsoft.com/en/default.asp
2. Adjust your security settings for ActiveX: Go to Internet Options/Security/Internet, press 'default level', then OK. Now press "Custom Level." In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to 'prompt', and 'Initialize and Script ActiveX controls not marked as safe" to 'disable'.
6. Install spyware detection and removal programs: You may also want to consider installing either or both of AdAware (free version) and Spybot S&D (freeware). Use these programs to regularly scan your system for and remove many forms of spyware/malware.
8. If you have not already done so, you might want to install CCleaner and run it in each user's profile: http://www.ccleaner.com/ ** UNcheck the option to install the Yahoo toolbar that is checked by default for the Standard version, or download the toolbar-free versions (Slim or Basic) when given the option for those.
9. If you use Adobe Reader it may need to be updated to be sure that you have a more secure version. If you are using a version prior to v. 6.05, you should update to 6.05, preferably version 8.1.0. It would be best to remove prior versions before updating to a new version. If you need additional assistance, the Adobe forums are here: http://www.adobe.com/support/forums/main.html
10. Make sure you are using the most updated version of Java. The current version is Java Runtime Environment (JRE) 6u2 You can go here to download the latest version of Java Runtime Environment (JRE) 6. Scroll down to where it says "Java Runtime Environment (JRE) 6u2 allows end-users to run Java applications".
Click the link to download the Windows (Offline Installation) package: Save it, do not run it. When the download is complete, close the browser.
Remove all prior versions using Add/Remove Programs, and delete the Java folder in Program Files. Reboot your computer once all Java components are removed. Then from your desktop double-click on jre-6u2-windows-i586-p.exe to install the newest version. Official JAVA Installation Instructions if needed. Reboot.
11. Practice Safe Surfing with with TrendProtect by Trendmicro. TrendProtect is a browser plugin that assigns a safety rating to domains listed in your search engine. TrendProtect also adds a new button to your browser's toolbar area. The icon and color of the button changes to indicate whether the page currently open is safe, unsafe, trusted, or unrated, or whether it contains unwanted content.
The following color codes are used by TrendProtect to indicate the safety of each site.
Red for Warning Yellow for Use Caution Green for Safe Grey for Unknown
13. This is an excellent resource for users of all levels. General computer maintenance as well as internet security is covered. Rootkits for Dummies (Paperback) by Larry Stevenson (Author), Nancy Altholz (Author)
You are in good shape. Yes, it is necessary to keep Java updated. It is just not necessary to have the scheduler keep checking for updates if you are accustomed to checking every so often yourself. Some people prefer these automatic notifications, and some don't. That's why that one is considered optional.
