What can you do when your system is infected by a virus, but you have no antivirus software on the system?

Trend Micro has introduced a free fix package that scans for and cleans out all the viruses that are recognized by Trend Micro antivirus software.

This tool supports the following features:

• Terminate all malicious software instances in memory
  
• Remove malicious software registry entries
  
• Remove malicious software entries from system files
  
• Scan for and delete all malicious software copies in all local hard drives

This tool is designed to run under Windows 9x/ME/NT/2000/XP.

How to Use System Cleaner:

1. Download SYSCLEAN.COM from Trend Micro site:
   http://www.trendmicro.com/ftp/products/tsc/sysclean.com
   
   
2. Create a temporary folder and copy SYSCLEAN.COM into this folder
   NOTE: This temporary folder should be created on a local or mapped drive
   
   
3. Download the latest pattern file (as in lpt482.zip where the last 3 digits indicate a virus pattern number) from Trend Micro site:
   http://www.trendmicro.com/download/pattern.asp.
   This file is in ZIP format and contains virus pattern descriptions.
   
   
   
   
4. Extract the downloaded ZIP pattern file into the created folder
   NOTE: To extract the zip file archive you can use the built-in features of Windows Me/XP or any unzip utility. For example, you can download and install WinZIP from: http://www.winzip.com/ddchomea.htm
   
   So, after all the abovementioned steps your local folder should contain two files as follows:
   
   
   
   
5. Close all applications running on your system
   
   
6. Run the System Cleaner by double-clicking the executable file SYSCLEAN.COM in Windows Explorer:
   
   
   
   
7. Make sure "Automatically Clean Infected Files" is checked and click "Scan"
   
   
8. At the end of the scanning process this fix tool generates a log file, SYSCLEAN.LOG, in its current folder. You can take a look at it by clicking the "View Log" button. To view the summary results scroll to the bottom of the log.
