From my personal (and limited) experience, I’d say that the Bitdefender Online Scan is the best choice.

However, while online scanners are great for lightweight infections, with viruses getting nastier these days, I’d really recommend that you use the free edition of Malwarebytes Anti Malware for removing infections. You’d have to download it but it really gets the job done like no other tool.

Just my 2 cents…

Cheers !

Malwarebytes And AVG works very well for me, always fixes it up most of the time. If not OS disc does it very well. lol – Scott Craighead
