Web-Based Virus Scanners
If you think you may be infected with something nasty there are some free web-based virus scanners you can use in an emergency:
Of course, these scanners will only detect viruses once they are in your system so their main use is as an emergency check, and if a virus has damaged your system these online scanners may not function properly anyway.
As always, the best option is to use a locally-installed virus scanner and keep it up to date. A local virus scanner is designed to detect viruses before you are infected.
