Sometimes you will need to do a online scan because the virus/orm have blocked the antivirus you are locally running on your computer. This might take some time, but you can leave you computer and do something else because you don’t have to do anything while it’s scanning.
I will list the best online virus scanners that I know. I use them often when I help people with viruses and spyware.
Maybe the best free scanner out there. Uses the same database as the famous NOD32 Antivirus, this means it’s always up to date!
This scanner is great because it leaves a nice logg you can examine, or send it to an expert.

This scanner does disinfect viruses, worms and trojans.
