After a week of setting up my new computer, I find that I get top do it all over again. AVAST decided the main component of Microsoft’s update system, trustedinstaller.exe was a Trojan earlier this week. I told AVAST to abort when given a choice between aborting and deleting the file, but AVAST apparently deleted file anyway. Worse I did not notice until this evening so there was no restore point left from before this update — that’s what happens when you are installing all your software. So it is reformat and start all over time (no Windows 7 disk with the system, just “system restore” DVDs). AVAST will never be on my system again. There are times I think anti-virus software is worse than the viruses.
