If you suspect your computer to be infected by a virus but no antivirus pack is installed on your computer, you can scan probably infected files by free antivirus scanner Kaspersky Lab. To scan the files , do the following:

Open/run the copy of your browser (Internet explorer, Mozilla, Opera, etc)
In the address field either copy or enter manually from the keyboard http://support.kaspersky.com/viruses/online
In the open window click Browse
In the Choose File window select a possibly infected file and press the Open button
Make sure that the file name and its path are specified correctly and press the Submit button
Wait until the process finishes
Acquaint with the scan results of a suspicious file

You can scan only one file at a time and its size should be not bigger than 1MB (if trying to load a very big file the server will display a technical page with an error message). If you suspect several files to be infected, scan them in turn or archive them (zip, arj, etc) and scan it. The size of an archive should also be not more that 1 MB.

If a possibly infected file is really infected with a malicious code known to Kaspersky Lab you will get the name of the malicious program corresponding to the records in the antivirus database.
