Disinfection
Automatic Disinfection
Starting from F-Secure Anti-Virus (FSAV) version 5.40, standalone malware (backdoors, worms, trojans, etc.) is automatically removed. FSAV automatically renames malware files to prevent them from being executed.
In rare cases, automatic disinfection is not possible and the user must instruct FSAV to perform disinfection (renaming and/or deleting the infected file).
In special cases, the user is recommended to perform disinfection using specific tools provided by F-Secure. The tools can be downloaded from:
- ftp://ftp.f-secure.com/anti-virus/tools/
- http://www.f-secure.com/download-purchase/tools.shtml
In some cases F-Secure Anti-Virus may not automatically disinfect a system. If so, please visit our Support pages at:

Windows System Restore Issues
If the computer is running on the Windows ME or XP operating systems, disabling the System Restore feature before disinfection is recommended. This is to avoid possible re-infection by a threat that has just been disinfected, as the System Restore feature may have unknowingly saved a copy of the infected file during its normal procedures. If the System Restore feature is active, it may then copy the infected file back to the hard drive after the user or an antivirus program has renamed or deleted it.
Instructions on how to disable the System Restore feature are here:
- Windows ME: http://www.f-secure.com/v-descs/sfc_dis.shtml
- Windows XP: http://www.f-secure.com/v-descs/sfc_dis1.shtml
Once disinfection is complete, re-enabling the System Restore feature is recommended. This will allow the user to restore the system to a stable configuration in the event that a crash or incompatibility issue occurs in the future.

Additional Details
This is the Trojan-Proxy General Information page.
A Trojan-Proxy is a type of trojan that, once installed, allows an attacker to use the infected computer as a proxy to connect to the Internet.
Trojan-Proxies are often used by hackers to hide the location of the original host from any investigating authorities, as the connection can only be traced back to the computer where the trojan is installed.
