I have to agree with Dave. I had a friend who got a piece of malware and ran amok on his system installing all kinds of software. Some of the software it installed was other antivirus programs. MS Security Essentials pretty much let the malware have its way with him. By the time I got to it to fix it he was pretty messed up and I opted to rebuild rather than fix.
I will wager $1 the reason you are happy is you have had no events. The day you have one you will realize how unprotected you have been.
Back on topic: I have had AVAST do the same thing to programs I have had for years. If you have otherwise been happy with them then just exclude the folder the gauges are in. Everyone runs the risk of having false positives show up.
