Exterminate It! Antimalware


Known threats:700,085 Last Update:March 01, 12:55


Having wasted better part of a day on a Vundo infection, which none of the antivirus/antispyware solutions I normally use came even close to handling (one of them actually compounded the problem due to a partial fix, causing all browsers to seemingly lose connectivity after a few seconds), Exterminate It! fixed it in a single pass and one restart.

Nothing short of perfect. A few dollars very well spent. Thanks again!

Why Is It Important to Remove Malware Files?^

It is imperative that you delete malware-associated files as soon as possible because they can be used - or are already being used - to inflict serious damage on your PC, including:

  • Disrupting the normal functioning of the operating system or rendering it completely useless.
  • Hijacking valuable private information (credit card numbers, passwords, PIN codes, etc.)
  • Directing all your Web searches to the same unwanted or malicious sites.
  • Dramatically slowing down your computer.
  • Gaining total control of your PC to spread viruses and trojans and send out spam.

    • The deletion of DD1B66D4.xml will fail if your Windows uses the NT File System (NTFS) and you have no write rights for the file. Request your system administrator to grant you write rights for the file.

Deleting Locked Files^

  2. Restart your computer.

The file will be deleted on restart.
