ls -sort with McAfee

McAfee VScan v4.5.0
settings - 
scan program files only
scan inbound outbound files

Problem.
This may not be considered a bug rather a notice to users. While McAfee is 
running, if ls.exe is executed with a sort option (eg. -t -s) Mcshield.exe 
sucks up about 98% of the CPU time causing ls.exe to perform very poorly. I 
believe Mcafee sees every single search access and scans the file. In a 
directory like /bin with many .exe files this is a problem. This probably 
happens with other virus software.
 
Solution.
Disable Mcafee while using Cygwin.
