Anywhere Internet Security Complete Free download and software reviews. Pros. Uses almost no background memory no impact on computer speed lots of settings to tailor to your needs website ratings in search engine results quick scans good detection rates in testsreviews. Cons. Not the best option if youre not always connected to the internet, as it relies on the cloud to function. Summary. I tried Webroot Secure Anywhere Internet Security after reading a PC Mag article giving it an outstanding review, and Im glad I did. It offers all the basics and no useless bloatware garbage that so many other anti viruses bundle nowadays. Most impressively, it uses almost no memory and has by far the least impact on computer speed of any anti virus software Ive ever used second best would be Norton Security, and the worst would be Bitdefender and Mc. Afee based on memory used and personal speed perception. Webroot offers plenty of settings for power users to play around with. And the web protection, which includes clear web site ratings in search engine results so you dont click on an infected link is among the best of any out there. Im a techie so I tend to try out new stuff because I get asked all the time what should I use for various software. So my new top recommendation for anti virus is Webroot, as long as youre always connected to the internet as it relies upon the cloud to check unknown processes and files. It is fast and offers just the right amount of features, and has excellent detection rates per reviews and lab tests. Reply to this review. Was this review helpful 1. Pros. No appreciable impact on system resources. Excellent heuristics and threat database refreshment. Robust administrative interface. Uncluttered GUI. Very flexible and feature rich user security preferences. Multi platform protection with single license each endpoint allowed five additional devices smartphone, tablet, etcCons. Adding devices requires several secure steps, which some could see as a a negative. Summary. Having been a longtime user 1. ESETs NOD3. 2, then Kaspersky 2. I was very reluctant to switch. However, NOD3. 2 became a bloated, resource hog from v. Switching to Kaspersky I noticed issues with resource impact as well. Webroot has been as invisible as any AVM package Ive used. My local tests continue to satisfy me. Webroot protects my systems from threats and attacks on a variety of levels. Their Webroot Infrared algo even provides advanced detection of zero day malware. Very pleased with Webroot. Reply to this review. Read reply 1Was this review helpful 1. Reply by gmccowboy on September 1. I agree, ESET is not what it used to be and is pretty heavy on memory use. I am quite impressed with Webroot. I also like Norton, which is light on resources with good reviews as well, but more expensive. Pros. Simple to use and fast. Cons. Does not actually work. Summary. Just purchased this to help remove some dllhost hijacking malware I ended up just wiping the disk. Webroot detected nothing. Spyhunter was a little better, finding secondary issues, though not the actual malware itself. Malwarebytes noticed and blocked the port usage. Vipre blocked a few things from running as well. So essentially it is a complete waste of money. Any kickbacks to CNET for their friendly article I wonder Reply to this review. Was this review helpful 1. Pros. Nice, fast online backup. The lightest AV Ive ever used. Absolutely no impact on system performance. Shark 3D 1080P Ita Youtube more. Scans entire computer in under two minutes. Cons. I cant figure out how this program works, or how to effectively test it. The price tag. Measly two week trial, need more time if im going to invest 8. Summary. Webroot no longer takes part in AV test dot org, Reps say its due to their product not being a traditional AV scanner and therefore should not, and cannot, be tested like traditional AV products. Skeptics say its due to poor detection rates, whatever the case I like this product and I think Webroot is the wave of the future, just wish I could have it longer, two weeks is not enough to be convinced Updated on Mar 2, 2. I tested this product with 1. Webroot only picked up 8. I denied and the last one, win. Delf SQL TROJ slipped by and rendered my computer completely unusable, forcing me to reformat my hard drive. Its too bad, I really wanted to like this program, but right now its just not ready for prime time. On a side note, Avast free detected and quarantined all without incident while Panda Cloud Free missed only three. Reply to this review. Was this review helpful 1. Pros. Seemed to work great at first removed possible threats and increased performance. Cons. a couple days after installing, Windows 7 would only reboot in a temporary profile. Tried uninstalling and profile still wouldnt come back. Had to restore operating system to a date before Webroot installation. No more Webroot for me Summary. Not worth the price. Basically, the old bait and switch. I believe most viruses on PCs are created by the hacks at virus protection companies. Any knucklehead can create a Windows virus. I recommend sticking with Mac, but if you cant, find a virus protection other than Webroot. Reply to this review. Was this review helpful 1. Pros. 1 Super fast so you can run it each time you log off the internet. Very dynamic interface a lot of choices under advanced settings 3 pretty much self explanatory 4 Quick access to guide. Cons. 1 Goes from 3. Seems to check different sections during each run. Webroot URL application rates my own Bravenet ad free websites low scores. These are self written websites and mostly just wordy articles, so whats unsafeMust be because Im a free lance writer, not a corporation. Support is kind of flimsy. Doesnt have very good uninstall options. When it warns against a page and you allow it to shut down, it closes all the other webpages. Summary. Ive only had Webroot for a few months. It is okay, Im not sure it is catching everything, but it hasnt deleted anything important yet. I dont understand all the terminology too well. Reply to this review. Was this review helpful 1. Pros. Fast Scanning. Sometimes Detects. Unobtrusive. Cons. All The Things You Are Piano Pdf. Didnt do its job for me. Now reaping. Detects infected USB Flash as Clean. Summary. I purchased Webroot secure anywhere, and recently have been infected with a virus which corrupted all my Microsoft word. The virus adds the extension festaazulcorrupta onto every doc or docx or xls file. Webroot didnt detect it. Also there is another virus which came onto my SD card which add 2 folders titled Hot Fotos My Musik 2. When i right click and scan the SD card, its still being found as clean. This was very disappointing. When i bought it, it was rated as 1 by Cnet. Now Im upset. Should just stick with Norton since its been around for long. Now busy downloading alternatives. Reply to this review. Was this review helpful 1. Pros. None at all. Cons. Webroot deletes files created by other software. There is no warning and no explanation. All you know is that software you have had for years suddenly starts going wrong and it can take you ages to figure out that its this crappy thing thats messing you up. If you have not yet downloaded, dont. If youve got the trial, bin it and get something else. If youve already parted with your money, you can partially salvage the situation by.
