Thanks for the replies, folks. My observations were much as described by others. The AV is an in-house furnished by my ISP, Cox.net. Not sure what it's based on. I should also mention that a Google search found no virus of that name. Happy Holidays, Peter
"The on-access scanning engine reported a 'W32/Trojan.MQN' infection in file 'C:\PROGRAMFILES\CCLEANER\UNINST.EXE' I believe the scanning took place when I opened CCleaner. The AV deleted the file. I rarely have viruses. Incoming emails are scanned, filtered, washed, rinsed, and hung out to dry. Any comments on a virus appearing as described above? Regards, Peter Yikes! Just got virus alerts in four more files!
