Just because you have received returned mail that you have not sent, or a bounced email from a server stating that you have sent a virus to that address, is not a definitive indication that your computer is infected by a virus. Actually, if you are encountering these types of occurrences, it is more likely than not that your computer is not the one sending the emails.
Today’s more effective viruses are much smarter than their predecessors; they setup their own SMTP (out going mail) server on the host computer, and select an email address to send to as well as an email address to show as the address sent from (in other words the virus was sent form a computer FAKING that it was your address sent from). The virus does this to avoid detection on the host computer. The addresses are usually acquired from the host computer either from their contact list and/or temporary Internet files.
On the same note if you are not currently using a virus scanner or firewall then it is advisable to look into the acquisition of one post hast.
To find out if you have a virus you can use one of many free online virus scan utilities. Just perform a search for “free online virus scan”.
Or try this one:
Trendmicro as previously posted also works very well but the company is not as well known as the one I have listed above which is Symantec best known for Norton AntiVirus.
Different scans may find different viruses so if you want feel free to use more than one (they are free). If you are infected the best thing to do is format, reinstall windows, and use virus protection from day one. Otherwise your taking a chance even if you remove the viruses found it is possible and likely that there are more that were not recognized.
For users of any Windows Server Operating Systems: The online scan may work (not sure) but Norton AntiVirus is for workstation platforms only, as far as I know. I am currently looking into finding good CHEEP server virus protection myself. If you know of any please email me.
