Strange Pop-up
Hello,
I have a problem with my iMac(intel). Sometimes when I turn it on, when it goes to the dekstop after the boot, a strange pop-up appears and immediatly dissappears so I am not able to see what it is saying. The only thing I noticed is that in this pop-up there is a yellow triangle( like an error message). I know my question is silly but is my iMac infected by a virus or malware? I have Sophos Anti-Virus which says that everything is ok. Please can cou help me? My version of OS X is Lion 10.7.2. Thank you!
iMac, Mac OS X (10.7.2)
