The practice of using cracking tools, keygens, warez or any pirated software is not only considered illegal activity but it is a serious security risk.

Cracking applications are used for illegally breaking (cracking) various copy-protection and registration techniques used in commercial software. These programs may be distributed via Web sites, Usenet, and P2P networks.

trendmicro.com/vinfo

...warez and crack web pages are being used by cybercriminals as download sites for malware related to VIRUT and VIRUX. Searches for serial numbers, cracks, and even antivirus products like Trend Micro yield malcodes that come in the form of executables or self-extracting files...quick links in these sites also lead to malicious files. Ads and banners are also infection vectors...

Keygen and Crack Sites Distribute VIRUX and FakeAV

...warez/piracy sites ranked the highest in downloading spyware...just opening the web page usually sets off an exploit, never mind actually downloading anything. And by the time the malware is finished downloading, often the machine is trashed and rendered useless.

University of Washington spyware study

...One of the most aggressive and intrusive of all bad websites on the Internet are serial, warez, software cracking type sites...they sneak malware onto your system...
Where do trojan viruses originate? One of the biggest malware distributors on the Internet are serial/warez/code cracking sites.

Bad Web Sites: Malware

If you use those kind of programs, be forewarned that some of the worst types of malware infections can be contracted and spread by visiting crack, keygen, warez and other pirated software sites. In many cases, these type of sites are infested with a smörgåsbord of malware and an increasing source of system infection. Those who attempt to get software for free can end up with a computer system so badly damaged that recovery is not possible and it cannot be repaired. When that happens there is nothing you can do besides reformatting and reinstalling the OS.

Please post the results of your MBAM scan for review.

To retrieve the MBAM scan log information, launch MBAB.
  • Click the Logs Tab at the top.
    • The log will be named by the date of scan in the following format:
      mbam-log-2009-01-12(13-35-16).txt <- your dates will be different from this example
      -- If you have previously used MBAM, there may be several logs showing in the list.
  • Click on the log name to highlight it.
  • Go to the bottom and click on Open.
  • The log should automatically open in notepad as a text file.
  • Go to Edit and choose Select all.
  • Go back to Edit and choose Copy or right-click on the highlighted text and choose copy from there.
  • Come back to this thread, click Add Reply, then right-click and choose Paste.
  • Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.

You're welcome.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

I prefer Firefox and use it all the time. If you're still have some issues with IE, see Slow Computer/Browser? Check here first; it may not be malware.
