Worst Antivirus Programs

These antivirus companies are so bad, your computer will throw up!
The Top Ten
1 PC Optimizer Pro

Bad customer service, bad software in general, mainly preys upon people who know nothing about computers. Scam software 100%.

It's fake. Don't waste your money on the "full version".

This is a malware.

Gains viruses

2 SpySheriff

SpySheriff is malware that's impossible to remove. Your computer won't like it.

This is old, and it wasn't even legitimate at all.

Dumb trojan "anti-" virus.

3 Symantec

Very good at annoying, slowing down PC and deleting non-infected files. Its capability of catching real viruses lies probably in deleting and blocking everything, which is not in an exception list. Got rid of it.

Norton used to be awful, but Symantec has improved a bit.

Worst anti-virus ever

Trash trash trash

4 Antivirus 360

It is damage Windows desktop.

Virus ads everywhere

Bad signatures

5 Webroot

Lol another dumbass who probably never even tried it

It isn't great as far as detection rates go, but it's good for older PCs.

6 Virus Shield

Not useful it and unsafe.

Heavy rouge security.

Don't installing it.

7 McAfee

It's absolutely awful, I hated it when it was bundled with my Windows 8 laptop, if anyone has this installed, UNINSTAL IT. It is a virus.

It Detects almost everything, and as a guy that likes torrenting games this is annoying

Slows down performance, and generates lots of fake alerts.

Poor Performance! Slow and need enough system resources.

8 SpyHunter 4

Very nice and worth the money, but SpyHunter 5 is better. Malwarebytes blocks it falsely.

9 Microsoft Security Essentials

You may as well just have no antivirus at all.

Bestestestest security system I ever didn't see. please don't use this it is very bad

It doesn't do anything!

10 Avast Antivirus

Well, it's a good AV with some great tools. But if you want to get some actual protection you need to get avast premium or some paid version. If you want to get it for free it will still work. But a lot of features like webcam protection, avast cleaner and stuff like that won't be available to you. I'd give it a 5/10 just because it's asking to be given money.

Avoid - one of the worst AV packages out there: it lures users that are not that technically minded with price - 0. Unfortunately protection offered by Avast is equal to the amount of money it costs. Had to many cases where oblivious friends installed this malware and afterwards came crying to me asking for help.

List of Crash: -
1. Audio Output Driver (yet to be repaired successfully)
2. uTorrent with its downloaded contents (mkv / mp4 inclusive)
3. Windows Real-time Protection disabled even after total annihilation of Avast itself

If you want premium, don't be surprised if it charges 3x or more than the actual price, that just happens with avast.

Whoever put this on is dumb. Malwarebytes is actually one of the best

Stop already! I don't understand why this is so overrated!

The best antivirus ever (for nowadays)

12 Stop Sign Antivirus
13 Norton

Had it on my old laptop, it basically ruined it because it never left the screen and overlapped applications.

It is slowing down my computer, specially email access to server.

The worst antvirus it's the thing that schools and mums would use

Iam a computer tech of 25 years...Nortons is worse than a virus, never believe these liars.

14 Protogent

Indian scam for stealing money from grandmas. The rap is excellent though

Some grandma probably: Oh and look! This anti-virus is sponsored by that PBS kids show my grandson used to watch! I guess I'll download it! *10000000 errors pop up*

Alrigt imma try to move this to number one even if I didn't make this list. I rickrolled them on the live support page of their website.

15 Kaspersky

That tool, that will randomly use 99% of the available computing power even though you configured it to only run while idle.

Probably a connection to Russian servers, Yes that might just be true.

16 AVG Antivirus

2018 avg is total crap, shame because older avg was good

I don't think its one but iv never tried it

Piece of Crap

The new avg is just awful! always trying to sell you something that you don't want. and very awkward to use.

19 Eco Antivirus

Very to much worst-ever.

This pc virus.

20 TotalAV

This is con program - total waste of money and time

Deleting it is impossible without using malwarebytes or manualy going in to your files and deleting it, it is rougeware

This is not an antivirus. This is malware.

21 Defender Pro

Very good, and it comes with the pc it detects everything almost

Might as well have no antivirus at all

Wont detect anything

Utterly pointless.

22 CCleaner
23 ArjunAV Internet Security

Best rouges security.

24 Bytefence

This is the worst antivirus program in my opinion it just goes bundled with other software programs and when you completely remove bytefence its still there it is so hard to remove this antivirus and it just downloads itself without your permission it also popups while your using the program it came with and if it's a screen recorder it will be so hard to remove bytefence you need to go to task manager and end task WHO HAS TIME TO DO THAT when your using a screen recorder to record your gameplay

People have been having issues with Minecraft because of ByteFence.

Trying to uninstall it takes hours, it is quite literally a virus anti-virus

The worst antivirus I have ever seen
