Avast anti virus attempted to blackmailed me Internet

Had my tech guy in for a tune up, and he updated all the latest versions of stuff, including AVAST ANTIVIRUS SOFTWARE.  When I rebooted my UPS WORLDSHIP SOFTWARE, which had functioned flawlessly for 2 years, it came up with an error code & shut down-repeatedly.  Called UPS WS tech support. Was told this was the 5 or 6 calls today for same probem.  Asked about antivirus software. Turns out AVAST had taken my UPsink.exe file, and quarantined it in it's "virus cest".  No idea how to get it out. Spent 1/2hour trying.  UPS TECH gave me AVAST TECH Support phone number. 

Got India on phone.  AN HOUR on the phone with AVAST "SENIOR TECH".  Downloaded program so they could "look at the problem" on my desktop.  Kept telling me there was NO WAY to "release" the file from quaranteen...Bottom line???  "We can fix this, it's not a problem with our software, it's an issue with UPS SOFTWARE & Windows, but we charge for this, now let me tell you how we structure the charges to correct your problem..."

EXCUSE ME?? Your software blocks a file, and I have to PAY YOU to correct the issue? NOT.  They REFUSED to correct it unless I paid them, and when I became irate at being BLACKMAILED, they hung up on me-2 hours wasted. 

I called my tech guy, and we decided to try uninstalling AVAST ANTIVIRUS, and it worked!  My UPSexe file was still there, and software booted up normally! 

AVOID AVAST ANTIVIRUS at all costs, or you could be next!
