If Bill wasn't so crap, you wouldn't even have to ask the question.
?Do you mean FREE, or free?
I found Avast takes too much processing and tends to slow everything down.
AVG worked best.
Each to their own.
Macs based on UNIX,(?) Linux is FREE, millions of, possible slight exaggeration, flavours, and virus free 'cos it's built in, not tacked on.....and on.....and on...
Another vote for microsoft security essentials which as others have said is free, been using it for a couple of years now, also worth doing a full scan once a week
I've stuck with the free flavour of Avast despite it bit greedy now (it wasn't when i first switched)... laptop came with McAfee free for a couple of years which was pants. Both it and AVG would occasionally miss things that Malwarebytes caught. I decided to try Avast as it offers a boottime scan. It found a couple of things that all the others have missed and since then Malwarebytes has never found anything to the point i've given up running it regularly
I've run Norton in various modes for over 11 years and have never had any problems .. One thing I stopped doing years ago was using free things.. nowt in life is free especialy in puters .
It seems that there is always something in the freebies that takes up extra space & speed on the outer
you too Paul?.... just had both raid disks, network raid storage and usb drive murdered,,, fortunately i also run a backup on a linux server..... ( too long as system admin to not do plenty of backups )
I no longer trust avg..trying adaware av at the mo
3 days on & i am still installing stuff.
cant afford to migrate to linux, too much legacy sw that wont run under wine that i cant afford to replace
MS SE is light and fine. Avast free has indeed got noisy in recent months, got it here but will prob get shot and go MS SE again.
None are perfect though. Malwarebytes is good as a second opinion, I use the free scanner, and Vipre Rescue sometimes. "Super antisypware" has a crap name but works well too alongside an AV.
AVG and Avast tend to be resource-hungry, and even when set to work in the background will slow down older machines considerably. They only work okay if you do regular scans with them.
When I worked in computers we used to put one or the other on customers' machines before they were sold. Six months down the line we'd sometimes get a machine back in for a virus problem. A quick check of the logs showed the customer had not run the AV regularly; sometimes never.
When set to automatic scan the customer usually turned it off after five minutes, "Because it slowed everything down".
If you use a freeby, make sure to let it scan the whole system at least once a week, preferably when you aren't doing much on the machine.
The 'Avira' Psymon linked to above is pretty good too, and has a lighter resource footprint, so better for older machines.
As already said, only Windows have these virus and malware infections. We have run one of our four machines on Linux for years, in various flavours, and have never ever had virus problems.
thats why i started a linux box..... about 10 days ago, othewise i would have lost a few weeks work..... i have one "offline" backup that i run monthly, & one i run on 5th fridays.... but i thought a raid netdrive and a usb should be "safe" for daily.....no i shadow and write encripted backups to linux box.
