It seems to catch more than some other programs.
I’m an IT professional with 23 years experience and I still get viruses even though my computer is protected with anti virus and anti spyware software.
The secret is to be fully backed up, I use carbonite.
What do you think of sandboxie? Is this a good program to isolate a virus so that changes can’t be made to your registry.
You should have a look at Acronis software, it is an image back up to an external drive.
If you ever run into a problem, just reinstall from the back up and everything is put back the way it was when you last backed up.
It's inexpensive and easy to use. I had an HD failure on a Dell laptop, went to Fry's for a new one and had the machine back up in an hour or so, OS, programs, everything.
For me it was a life saver as I have a business I run from my house so the data on my drive is very important, I highly recommend it
I have 30 years of experience and I have never gotten a virus. Viruses generally result from sloppy skilz. Malware usually comes from mistyping a website name (microspft) and getting a porn site or people porn surfing. Porn sites are hosts for malware although more conventional sites are starting to see malware embedded in their banners. Most of the time, people give the malware permission to infect their machine (”You have a virus. Click here to fix it”).
Viruses must be executed to infect. We see this when people download movies, songs, porn, etc and run an infected file. Office files used to be a popular method of transport but that has waned.
FR cannot infect your PC. FR does not run ads.
