Virus - mst122.dll


I must have recently acquired some type of virus. My virus program picks up and quarantines (sic) some type of virus that is associated with mst122.dll. I continue to get the warning, but I cant seem to get rid of it via my virus program. Has anyone seen this?

Thanks, Vic

Install an updated full version of antivirus. Your antivirus might-be-out of date. I recommend you to use avast or avg 8. They will remove all the viruses they detect from your system. But remember to install only one antivirus because installing more than one antivirus can clash down your computer. After installing the new antivirus, scan your computer and delete all the detected viruses. Delete also your temporary internet files, cookies, cache,etc. To do this, follow these steps:

  1. Go to Start, Control Panel.
  2. Network and Internet Connections
  3. Internet Options
  4. In the Browsing History, click Delete...
  5. Delete Browsing History box appears, Click Delete All button found at the bottom.
  6. Reboot your computer.
Install also RegFix. RegFix helps to fix System Registry Errors and can also optimize your pc.

Run my new anti virus which picked up a problem on somthing called OLEPR032.DLL and gave me the option to delete it which I did (God do I regret doing that). How I keep have a pop up saying that this is...

Open up the help in XP and type do a search for System Restore Wizard.
Follow the instructions and it will give you a choice to restore your system to the way it was at an earlier date. Choose a date from before the problem started. Any programs you have installed since then will need reinstalling but you won't loose any data.

It may also restore the virus in the dll but you can find another way to fix that apart from deleting the file.

If that does not work you can boot from your XP cd and choose the REPAIR option.

I hope this helps

Operanting sistem in quarenten

Any antivirus; unless it finds virus, never moves a file to quarantine. If it moved, then probably your OS is occupied entirely by virus.
Which antivirus are you using? Are you able to login into your system ? If yes, open the quarantine folder and replace all items. It is best if you do it in safe mode. Then scan for that trojan horse again. But before that, back up your important data and then scan. I recommend you remove all the virus after backing up of data and format your system once (all drives) and do a fresh install of OS.

If you are unable to open quarantine, try system restore to restore to a point earlier before that scan. It is in All Programs>Accessories>System Tools.
