Check for malware
Malware check
1) Microsoft Malicious Software Removal Tool
Hold down the "Windows key" ( Bottom row with flag ) and press R
Type in .....> MRT <..... and press 'OK'
Run the tool from your desktop using a full scan

2) Malwarebytes
Download the free Malwarebytes program and run a full scan.
It will deal with anything it finds without having to upgrade to the paid version
On the website use the "Products" tab to access the free version

3) Scan your Windows files for errors and repair (automatic)
Hold down the Windows key and press R
Paste in ...> sfc /scannow <....and click OK


4) Blank Messages XP Home Edition and Professional users only

Hold down the 'Windows Key' (Bottom row with flag) and press key 'R' - Type or paste in ..... regsvr32 jscript.dll ... > OK > OK (if successful)

If it fails to register check this microsoft website

5) Check and delete non Microsoft entries in IE Security Zones
If you are unhappy about deleting items in the Registry make a Restore point at this stage.

Hold down Windows Key + R - type or paste in.... regedit .... > OK
Expand the Main headers as you proceed by clicking the arrows or the boxed + to the left

HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Internet Settings > Zones >

You'll see a number of folders numbered:
0 = Computer or My Computer (Not shown in IE by default)
1 = Internet
2 = Local Intranet
3 = Trusted Sites
4 = Restricted Sites
If there is a rogue entry it will probably be attached to the 0 or 1 Security Zone - highlight and delete it > Ok
Close up the headers before leaving the Registry.

6) Check your support software is up to date

a) IE - IE is coded with Yahoo Messenger so it needs to be kept up to date and clean. It is unnecessary to make it default - it will work quite happily in the background.

b) Java
http://java.com/en/download/index.jsp
Check your version by using the link below the 'Download' button.

c) Flashplayer for IE (even if you have another browser set as default)
Launch IE and visit this site
http://www.adobe.com/software/flash/about/

7) Clear the Messenger Cache - use this page - find your OS and click the link

8) Uninstalling from the Control Panel is ineffective as too many files, fragments and Registry entries get left behind. You will have to use an uninstall tool that scans the C drive and Registry after the Yahoo uninstall software has finished
Download 'Revo' its a free uninstaller that will scan your C drive and Registry AFTER the yahoo uninstaller has finished, and offers everything up for deletion.
http://www.revouninstaller.com/revo_uninstaller_free_download.html
Use the 'Download' button at the bottom of the 'Freeware' column
When you upload the program it will open with a display of all the software installed on your computer
Make sure you have no other programs running during the uninstall -download and upload.
Save your Messenger Archives if required. Does not apply to version 11 the Archives are on the Yahoo Servers.
Double click on the Messenger icon and select the 'Advanced' option
Revo will make a Restore point and use the Yahoo uninstaller software initially. Ignore any prompts to restart your computer.
When the Yahoo Installer has finished it will do a scan of the Registry and C drive
Select everything it finds and delete everything. First Registry and then files.
Clean out your browsers
Download 'ccleaner' and use it daily. Run it through a couple of times,using the factory settings
and the 'Analyze' control to see the files offered up for cleaning. Use 'Run Cleaner' to delete
these files and then run 'Analyze' again to ensure all files are deleted
Run the 'Registry' from the left hand toolbar but 'Save' any changes after opting to 'repair' errors.
Never make changes to your Registry without saving the information.
