Worst Antivirus Programs

These antivirus companies are so bad, your computer will throw up!

The Top Ten

1 PC Optimizer Pro

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

Gains viruses

PC Optimizer Pro is just another shady "PC cleaner"�"not an antivirus product.

2 SpySheriff

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

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

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.

"This antivirus is the best! It destroyed my computer! I love wasting $50 on a basic package! "
Oops, sorry for being sarcastic. Symantec is freaky, horrible, and unlovable. - Target

Norton crashed itself... then my computer.
Thanks, Norton. You are the worst antivirus ever.

4 Antivirus 360
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 McAfee

Slows down performance, and generates lots of fake alerts.

Poor Performance! Slow and need enough system resources.

The slowest antivirus ever?

Very slow computer now

The Contenders

Avast is one of the best, idiots..

12 Stop Sign Antivirus

16 TotalAV
17 AVG Antivirus

Piece of Crap

18 Kaspersky

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

19 CCleaner
20 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. - allamassal

21 MacKeeper


22 PC Cleaner
23 Advanced System Care

It's fake. Nothing to tell about it. But one thing-"It completes full system scan just in10 seconds."

24 RegClean Pro
25 Sophos Anti-Virus
