Antivirus – Entertainment Game Review
Antivirus is a Entertainment/Simulation/Strategy game from Christopher Larsen, first launched in 3rd February 2009.

What Makes Antivirus Stand Out
NEW Antivirus V1.2 just released!!!
Antivirus Lite coming soon!
V1.2 is a MAJOR revision to Antivirus.
- Greatly improved Graphics and Animation!
- New High Scores Feature!
- New Game Over Screen and Upgrade Menu!
- Improved Sound and Special FX
- DOS Virus just as annoying as ever!
V1.2 adds a lot of polish and makes for a richer experience, taking the Tower Defense genre in a new direction with it's sudden-death Virus theme and strong strategic elements. We've taken feedback from our fans and critics alike to make AV a better game that continues to grow and evolve as the infections spreads…
Game Description:
Malware, Spyware and Trojans are attacking through your internet connection! They must be stopped!
Spin up the CPU and power up your WiFi, Firewall and Barricade defenses while you blast Viruses off your System with an arsenal of countermeasures like the Laser Scanner and Quarantine Field!
Choose one of six Internet Connection Configurations, fend off a dozen different types of invading Virus, you have TEN High-Tech upgradeable defenses to fend off this assault on your hardware.
A slick user interface and a wealth of strategic options make managing your hardware easier, but it’s your skill that will harness this power and keep your System free of infection!
If you've ever fought with a Pop-Up or kept a wary eye on a Phishing scam, this is your chance to take back the Net! Take your CPU on the offensive, and cleanse the internet of these marauders once and for all!
This is the most fun you’ll ever have for less than the cost of a pizza!
You pay for the app, but the addiction comes free.
Prepare to be HIGHLY unproductive.
Not convinced by our excessive use of exclamation points and caps? S'ok, check our free version Antivirus Lite. We think you'll convince yourself to come back and go for Full-On Antivirus. :)

Player Experience Highlights
Community Insight:
Excellent game with a good concept. Been playing this game since 2010.
This is a good game but theres no way to save and theres no way to earn currency. Still itd be more fun to play with the controls on a real anti virus. But this app is great just need to fix some things.
This game is extremely entertaining. Though we'd like a few added features. Sandbox New virus: root kit Root kit: flyer, invisible until halfway through the map. New tower: detector Detector: increases range of nearby towers, able to detect root kit regardless of position as long as it's in range. We also would like the port probe to be nerfed. Seriously it just blasts through our defenses. We get reload. We sell our towers. The only counter late game is just having an extremely strong economy. Maybe make it so it neglects 1/2 damage. But having it take 1 per hit is to OP. The port probe and pop up are the only things we die to. Usually at lvl 80-lvl 100.
App Store update broke buying and restoring full version as they did with a lot of games.
This game is really fun but, there are a few bugs. For example, when you upgrade the range for the surge tower, it cost much more power than it shows. And we mean MUCH more. The last upgrade costs like 19 power! No save function disappoints us. A sandbox mode with all the towers and infinite power would be great! Hopefully you will update this game more often…. Was our previous review. Now we've seen we're expected to pay for the full* version despite having bought this years ago. Great job dead rat, milking your supporters.
This is our favorite td app. Extremely addicting! You will definitely not regret buying this app. We have been playing this game since it was first released. Amazing update guys.
Awesome game, we love the new update with all of the new towers and viruses!! We hope to see this game on the top 25 soon! Also thanks for the ice tower bug fix. Hope to see player created maps soon.
Definitely a challenge, but that's what makes it fun. You do have to manage resources carefully. The creeps that can damage in path defenses are gonna get ya! Our only complaint really is that the campaign isn't a campaign. It's random. We'd love it if there were fixed levels to work through and complete. It's a fun game, but there isn't anything to accomplish per se.
This game is great! We have been playing it off and on for the last 2 years! We love the new story mode and we could play all day with the regular game. It's different every time. The only problem is that it does not save your game. If you simply close the screen on the game it will stay up but if you exit the app for more than a couple of hours you can't come back to where you were. And we've lost some of our best games that way.. Please fix.
This is actually a pretty engaging tower defense game, but it has some problems that keep it from being a 5-star app. First is the lack of a SAVE function. Obviously the longer the game, the better you are doing; but that means you have to carve a large (and undetermined) amount of time out to play this, unless you don't mind aborting a game when you get called away. Because if you pause it for awhile, your game just disappears and you start over… High score LOST. Next, the campaign mode, which also doesn't have a save function, starts you over from level 1 every time you lose. So, it's not a proper "campaign" game at all, it's just a variant of the regular game where, instead of infinite waves on the same map, you get breaks and change maps in the "campaign" game. And here's a bug: there is a separate high score list god the "campaign" game, but your campaign scores won't show up on it — they just go onto the same list as the regular game. There is also an upgrade bug in Pro that was not present in Lite: when you go to upgrade your units, the "recharge" time shows up (it's one of the features you can upgrade, improving a tower's fire rate), but the RANGE and DMG numbers are blank. You can upgrade them… The cost to upgrade shows up and you can see the improved range, for example, but the star telling you what the current range and Dmg are is an empty box. It's a shame because without those hiccups this would be a 5-star game go sure. It's attractive and stylish and the theme is entertaining. As it is, we wish we had stayed with the LITE (free version).
This game is okey don't find it fun anymore since the new update.
We wrote a review of this game a while ago, and since then they have listened to all of our feature suggestions! This is one of the few games that we have continued to play for so long.
We use to love this game but after the update we hate it return it to the old version.
The new version stinks. Now you have to have batteries to play also it cost to change what you want to put out. This game use to be a big addiction of ours now not so much. We could even live with the we can't save option. By the way great graphic just bad move on changing game design. Bring back the one energy every round no matter what also why do we have to pay to switch between batteries and weapons. Is there any way to uninstall an get the old version back.
Finally am update for the original game!! We have been waiting for this. No more lite version 4 us WOOT.
We got it a long time ago for only 99 cents and it gave us the free update that we were unaware of and noticed that this game was a lot better and one of the best tower defense games on the app store.
Used to be great but after the latest update, the app constantly crashes.
Ok, turrets like logic bomb, sweep, disconnect, and purge crash the game when they hit more than one enemy. "blue" turrets like firewalls and ice crash the game when they are activated.
Best game ever Was one of the first apps we bought when we got our iPod. Best app in history of our ipod.
Could be a bit better if it was updated for retina display but other than that it's awesome and definitely addicting lol.
Great new TD game with some unique twists.
Love it. We play it all the time. We can't seem to get passed level 44 (E4 C10)… We still haven't figured out what the WiFi does in this game. Keep up the good work.
This is one of the best TD games in the app store. The combination of tower types and the no-money upgrade system makes this a really unique game. Enemy types differ from one another in many more ways than just strength and speed, making this game far more about strategy than other TD games. We'd give it 6 stars if we could. Nicely done. *****.
Now that the save function is in, this app is great.
We really like this game! After playing the lite version non-stop for a month we decided to get the full version. This is probably the most addictive tower defense game we've ever played! We look forward to the updates to see what's new.
We love this game! We can play this for hours… Version 1.1 is much more balanced than the lite version. But 1.2 NEEDS to save your game between levels or something for two reasons: 1) The game quits when you get a phone call and you lose everything you were doing; 2) It would be awesome when you lose the game to be able to load the saved game and try to correct your mistake that made you lose on the first place!! Excellent game guys.
It would be better if we could listen to music while playing. Thanks for the game better than tap defense.
Great TD game. However, needs to be updated more frequently with new maps, towers, etc. Will definitely give 5 stars when the app gets further developed. Recommended buy; it's a ton of fun and a very neat idea for a TD game. We strongly feel this could be our favorite game for iPod if the developers would make a conscious effort to update the app periodically.
This game could use more maps or something now its been a year we still have it cmon lets see some mor dev on it please.
This game is very addicting but it would be so much better if you could listen to your music.
Please make an easier difficulty! Other than that the game is good.
This is a very good TD app, and it took some experimenting to learn the combinatios that would allow us to get past the first wave even ;) Keep of up. When we first saw the app, we bought it because we thought it looked and sounded just too awesome to pass up. A little more variety in the towers could get that last star.
The game is very good (see title). The style is very nice and the entire game is cleverly made. But it could be better. Music, as well as maybe one or two more weapons or such would make this game perfect.
Very addicting! We love it! There are just two things keeping it from 5 stars: 1) everytime we exit the app we have to restart from the beginning so can you fix that please.2) More weapons. If you include those two things then 5 stars.
Its fun addictive and still hard.
Ever since upgrading iOS, the towers don't show up on the board when we place them. If you tap where they are, it brings up the modify screen, but you can't see them. Loved te game until now, buts makes it unplayable. FIX PLEASE.
Update messed it up. If you start a game then exit out of the app the next time you reoopen it the whole app freezes.
It needs more tranistion and smoother flow.
