(PC) Protection evaluation with test virus.

Posted for Dan Hirsh (818) 505-2285

I tested McAfee's SCAN77 using Rosenthal Engineering's new release of
Virus Simulator (I've seen posted as VIRSIM11.COM on EXEC-PC,
Compuserve and others).  It seems that SCAN77 misses three boot sector
viruses that SCAN76 found on the same disk.  Both versions of SCAN
found nine viruses in the .COM, four in the .EXE and seven in the test
memory virus.

THESCAN, F-FCHK and VIRX also found the test viruses, but Norton's
Anti Virus couldn't find anything.

There's been a number of postings about scanner producers bragging
that their scanners search for more viruses than the next guys.  Well,
it's not how many viruses your scanner looks for that counts.... It's
how many you can find!
