Grisoft, makers of AVG antivirus, on Wednesday released a new update addressing a false positive in another security product.
On Tuesday, AVG users reported desktops warnings that their desktop was infected with something called Trojan Agent r.CX. Some files within zlsSetup_70_483_000_en.exe, a compressed file containing dormant set-up files for Check Point's ZoneAlarm, apparently set off the alarm. The ZoneAlarm user forum soon filled with concerned users.
Grisoft did not respond to a request for comment.
Laura Yecies, vice president and general manager of Check Point's ZoneAlarm consumer division said, "as soon as Check Point learned that AVG's recent antivirus update was mistakenly flagging a ZoneAlarm file as a virus, we contacted AVG and they issued an update within hours that corrected the problem. AVG users will automatically get the update that corrects the issue."
In July, Grisoft modified its free AVG 8 due to complaints about a proactive scanning of a Web site feature. The feature that had been enabled in the paid version of the product did not scale with the free release causing spikes in Web traffic.
