Malwarebytes Blocks Internet Access (com Port Disabled)

We were so very very happy and pleased that Malwarebytes free version helped clean out the InternetSecurity2010 virus/trojan infection, thereby resurrecting this Toshiba Satellite (WinXPMediaEdition2002,Sp3).

That.... we purchased a key code enabling Malwarebytes to run all the time

We did this despite some warnings by one or two posters on this site... '

well,

we have found out that Malwarebytes ... first...blocked access to one of our email IP host sites. After over an hour of searching, we found out how to add that site to the program's "ignore list' so that it stopped blocking that access.

Now we have discovered that Malwarebytes has disabled com port 3, which our internal modem was using to reach the internet.

SO, we have disabled Malwarebytes. We still appreciate the fine programmers at that company ... but the keycode fee to enable realtime operation of their program is, we regret to say, best donated to St. Vincent de Paul (or Goodwill or Starvation Army) instead.

Does anyone just happen to know how to fix this easily in Malwarebytes, (the Device manager is no help) or else we will defer buying all the additional licenses were were planning for our other computers....
