Go to http://housecall.trendmicro.com/
and run an on-line virus scan.
I've been using Trendmicro for almost 1 1/2 yrs and have had no problems with it....Definitely check out the website,just might find what you really need.
I'm running Trendmicro'* Internet security
It can be set for 3,6,9 or 12 hr updates on the virus definitions. I scan daily viruses and have only had one get past in the 1 1/2 trs I've been using it.
It was an selfinstalling autodialer that slipped through in a pop-up.
I think it is great!!!
