Now when I boot the machine, Avast popup says, "Your Avast Security Report: 300,000 files have been scanned in the last 30 days. Want to know how many are infected? Click here" This sounds more like an irresponsible scam to me rather than in antivirus program.
Then it says, these sofware updates are CRITICAL. Install them now. Before, it came up with this and mentioned what the updates were. I looked all over the Internet, including the host website - and no word whatsoever about it. This time Avast mentioned no specific updates. I'm very leery about this.
