Google has warned users of a third party add on for eBay used by many sellers that it is potentially malicious after being infected with a trojan.
Auctiva provides tools for sellers on the popular auction website.
The company confirmed a virus had attached itself to files on its servers but remedied the problem soon after.
However, Google continues to warn users searching for the site that it “may potentially harm your computer”.
The trojan, called Adclicker, is classed by security specialist Symantec as a “very low risk”. It is designed to “artificially generate traffic to certain web sites” and is used by malicious hackers to boost clicks to online banner adverts or to inflate web statistics.
On its community forum Auctiva said that it had “initiated a request with Google to have our site cleared from being reported as a malicious site”.
