Cautious is the right word.I was dupped by PC Pro Cleaners, I will say this I asked for my money back same day, lets hope they credit me back like they said they would.money money, that's all it was about, they do these faulty scans to make you think you have major problems.even after they did this, Norton (whom is (was) my virus protector) and who I trusted came on and said I needed to download a tools removal. Ha ha when I did that, my Norton was deleted, I am now with AVG which I have on my other computer.I will never trust any other! PC Cleaner comes with a long history. It's known to display exaggerated reports, most likely similar to the one's you received. Report from Symantec goes back to 2007. As does from an extremely reputable site.
