Security Software You'd Never Go Back To

AVG, Avira, BitDefender, Symantec, Ad-Aware, ZoneAlarm, Immunte, McAfee, Sophos, SUPERAntiSpyware, Zemana, SpyBot, F-Secure. K7 and QuickHeal.

This is the list of AVs or security products that I don't wanna install due to bad experience.
Which kind of troubles did you encounter with avira and Symantec? When?
 
Panda, they have the bad software and some how even worse tech support. Loaded Panda just to test it out, it almost destroyed by system it was so buggy. First I couldn't uninstall it the normal way, had to download their official uninstaller. Uninstaller did not work either, kept hanging midway. Contacted tech support, they said that support was only for paying customers even though it is advertised as free on their website. Never returning to them ever again.
 
No matter what AV/IS product i used i never got infected. 2 and a half decades into IT industry will 'grant' you that 'benefit' :). But the product I don't even want to test is certainly McAfee. To tell you the truth i use security products only to test them. In my case Windows Defender with Windows Firewall Control (and Zemana as control point) is all i could ever need.
 
Which kind of troubles did you encounter with avira and Symantec? When?

This year.
Avira: Performance issues, low PUP detection, can be bypassed very easy, flagged malware as goodware, crash the PC if the malware is a drive-by and can be terminated by malware.
Symantec: False positives, signed PUP can bypass, no ransomware protection, PC freezes on removal of advance threats (exploits), can be terminated by malware and the Xvirus detection.
 
1/ norton: buggy, very bad usb protection that I got infected by a very old virus that any other AV can detect
2/ AVG: slow, ads, bugs, can break pc
3/ bidefender: always causes problems with IDM that after finishing download, network kept running at the same rate
4/ panda: slow scan, some bugs, can't remove some infected files
5/ avira: memory leak (>1.4gb after playing games). Maybe fixed, who knows
6/ G-data: extremely slows down my pc
 
1: AVG : the few times i used my pc got infected, high resources pc
2: COMODO firewall : make some test with some friends who know how to penetrate into other pc.. comodo failed.. ( i will give a try the comodo V 10 when release anyway)
3: any program for " boost pc or fix regedit": those just broke pc many times.
 
Each security product has a problem. That's why I decided to stay with defender on Windows 10. Plus, if you are a security expert and you can use great tools like virus total, sandboxes, virtual machines, malwr malware analysis, why do you need a third part security software? The only dangers are exploit kits and infection via flash drive.

I like running security software to be sure that I am safe. If you feel comfortable good for you. :)
 
Iobit in terms of Antivirus product because of so poor and no development on their own engine which turned out to borrow license for Bitdefender.

Next is Superantispyware where the product became non existent + its owner transfer to Support.com which known for some questionnable reputation.

I've never suffered any bad experience as tested the antivirus software however no plans to install again because of not paranoid on threats.
 
Avira - They whitelisted (celan verdict) some ransomware samples that I submitted. I sent them again to change the verdict no luck! Good bye!
AVG - Worst privacy policy and I saw AVG on infected system that I cleaned.
Avast - No words, I just don't like it.
Ad-Aware - Just a signature AV
Comodo - They always hide their sandbox feature and don't want to improve other things. They just say "we have sandbox".

Now I just thought and I hate every of them!
