Only if they have succedded in placing a particular script on your comp in the Internet temp files................. it is possible but not so easy to do

Personally I use online scanners as a last resort - especially if I am on someone else's computer trying to fix it and they do not have an AV problem installed or if it is playing up

Hey Guys,
Below is an email message I received from a virus research firm. What is alarming is the indications that a hacker can get into your system if you use a free website virus scan at two of the sites listed below. I use website virus all the time; usually housecall but occasionaly I use Panda (very very slow).
Researcher Claims Online Anti-virus Scanners Buggy

UPDATED: Online scanners from Symantec, McAfee and
Panda all contain buffer overflows. One researcher
claims an attacker could execute arbitrary code,

and McAfee confirm the browser crash.

An Israeli security researcher claims to have found
security holes in the free online scanners of three
major anti-virus companies.

Rafel Ivgi, also known as "The Insider," in posts to
several security mailing lists, claims that Panda
ActiveScan, McAfee FreeScan, and Symantec Virus
Detection all suffer from buffer overflows that could
allow an attacker to crash the system and potentially
execute arbitrary code.
