It's a two step solution:
First do this: Download this scanner ( http://search.yahoo.com/search;_ylt=A0geu7M8pWtJlysAMmtXNyoA?p=Malwarebytes'+Anti-Malware+downloads&y=Search&fr=sfp&ei=UTF-8&pop=1&rd=pref - choose the first link after the sponsored links that contains this text: Come to CNET Download.com for free and safe ) and follow these instructions: Install the application.
* Make sure a checkmark is placed next to Update and launch, then click Finish ( If an update is found, it will download and install the latest version).
* Once the program has loaded, select "Perform Quick Scan", then click Scan ( The scan may take some time to finish,so please be patient).
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart ( The log is automatically saved by the program and can be viewed by clicking the Logs tab).
And secondly, here is my technique on how to do a cleanup: tricks (and free programs) I use for problems, slow PCs or the likes.
1) The Java Runtime Environment causes issues, you should use a free program I use myself called JavaRa ( http://raproducts.org/javara.html ) to get the latest JRE and remove older versions. This will ensure the security of your computer and extra space on your hard disk. The download link is here: http://raproducts.org/ ( Currently, JavaRa supports Windows Vista without UAC so if you are not comfortable temporarily disabling it, don't use JavaRa )
2) Flush every single possible accumulated junk in ALL your browsers. As you explore the web, browsers stores information about your browsing. You should delete that information from time to time.
Method One (now): In Internet Explorer, click the Tools menu, then Delete Browsing History and in the box, click the Delete all button (bottom left) and Yes.
In Firefox, go to tools, clear private data, make sure all boxes are checked and then click on the clear private data now button.
Method Two (in the future - about every two weeks for normal use of the internet - every week for heavy use):
In Internet Explorer, click the Tools menu, then click Delete Browsing History and in the box that opens, do the following steps (in order)
1) click the button near Temporary Internet Files, click Yes and wait for the box that opens to close.
2) click the button near History, click Yes and wait for the box that opens to close.
Finally, click the close button (bottom right) to finish.
In Firefox, Go to tools, clear private data and uncheck all except Browsing History, Cache and Authenticated Sessions boxes and then click on the clear private data now button.
Note: You should close your browser ( This is good for Internet Explorer and Firefox ) when you're done to clear cookies that are still in memory.
For older versions of the programs or for other browsers, check help files for guidance on doing the cleanup.
3) Turn off the restore point utility ( here is a guide for Vista: http://windowshelp.microsoft.com/Windows/en-US/Help/9f6d755a-74bb-4a7d-a625-d762dd8e79e51033.mspx )
4) Install a free cleaner called Glary Utilities ( http://www.glaryutilities.com/gu.html ) to remove junk files and/or remnants of installs (there is always some) and use it in Windows "safe mode" (for a better cleanup job).
5) Get back in normal mode and, as a final touch, defragment your drive with your choice of defragmenter (built-in, freeware or open source).
6) Turn system restore back on. ( the same guide and article given in part 3 )
( A word of caution, with programs this powerful, be sure to read all instructions and help files completely so that you can apply fixes right the first time ! )
So here we have it, this will guide you to a working better and faster protected machine.
