Truly free Virus Scanners
Virus scanners operate by searching your harddisk(s) for files which might be infected by a virus. This method is never 100% secure, since only known viruses (or known virus patterns) are detected. If an infection has been detected in a certain file, the virus scanner might be able to clean the file, but very often this is not the case. In that case, you can try another scanner to clean the file, you can try to replace the file or - as a last resort - delete it.
However, if many important operating system files are affected, it might be the best solution to reformat the harddisk and install the operating system from scratch.
There are even viruses can not be cleaned by mere hard-disk reformatting. E.g. so-called boot-viruses infect the boot-sector of disks, and will very often not be removed by simply reformatting the harddisk. In this case you will need to repair the boot-sector, a good utility for this can be found in Norton Utilities (not free).

Email protection
Mail Washer FREE This very useful freeware program enables you to delete virus emails and spams directly on the mail server before download. This not only saves costs and time, but also reduces the risk of virus infection.
Other features: bounce mails, blacklist mail sources, preview, show mail headers, filtering.
GFI Email
security test
Due to the unsafe design of some email programs, email viruses now are able to infect computer systems just by email. Once infected, a computer system can spread the virus further by sending malicious emails to other systems without any human interference. Well designed email programs do not display these vulnerabilities. Unfortunately, commercial success is not related to good design...
Virus scanners (please see above) can offer good protection against email viruses by scanning each incoming mail, but will never protect against 100% of all attacks, since it is impossible to know and detect each and every possible type of virus.
Therefore, even when you have a real-time virus scanner, it is wise to get some information on the vulnerabilities and strengths of your email program. The GFI site tests your email program by sending you number of emails that probe your mail system.
How not to get an email virus Prevention is the best cure when approaching the hazards of email viruses. This article, written by Dhugael McLean, explains how to best handle a variety of email attachments, and which file types you should never open when they are sent to you by email.
Outlook protection Some Outlook and Outlook express versions are very vulnerable to virus attacks through email. Several versions of Outlook and Outlook Express can execute malicious scripts or programs hidden inside emails sent to you without warning. A patch for Outlook Express to diminish this security risk can be found on the Microsoft Web site.
Patches for Outlook and Outlook Express can also be found here.
The VCATCH program can protect both Outlook and Outlook Express from virus emails.
