Update & Virus Database Issues
The ESET software used to work fine, but lately updates are failing constantly. I reached out to technical support, but their instructions were confusing and didnât help. The app keeps alerting me about outdated virus definitions. I expected better service.

Vulnerability & Patch Management
Patch deployment with ESET feels inconsistent. Some vulnerabilities remain unpatched even after alerts are raised. Technical support acknowledged the problem but offered no clear timeline. Reaching out through the ESET phone number didnât help much either, as the guidance felt rushed.

Installation and Activation Problems
I recently installed ESET on my computer, but the performance slowdowns have been frustrating. I reached out to their customer support, but the response was delayed and unhelpful. The technical support team didnât seem knowledgeable about the issue. Overall, ESET didnât meet my expectations.

Blocked internet access
ESET software suddenly blocked all my internet access, which completely disrupted my work. I contacted their customer support through the website, but the chat responses were slow and generic. They asked me to perform several steps without explaining why, and the problem was only temporarily resolved. I expected a more professional and quicker technical support experience.

Detection Issues
ESETâs detection system missed several viruses on my PC. I reached out to their customer support, but technical support was unhelpful and slow. The ESET phone number didnât make it any easier. Disappointing experience.

Update failures
After subscribing to ESET, I needed help with setup. Tried contacting technical support and calling the ESET phone number listed â the calls dropped, and support tickets took too long to get a response. The few replies I got lacked clarity. Overall, very average customer support.

Scanning Problems
ESETâs scans constantly fail on my system, and it never identifies the reason. I contacted technical support hoping for a real fix, but the answers felt scripted and unhelpful. I even tried the Eset phone number, only to be transferred around with no solution. The experience left me frustrated and unimpressed, especially for a service expected to be reliable.

License Key Not Working / Activation Problems
Iâve never struggled this much with a product activation. The license key wouldnât work, and customer support couldnât fix the issue even after several attempts. Technical support asked me to wait for an email that never came. I called the Eset phone number hoping for faster help, but still no real resolution. Very disappointing performance.

Email Protection / Outlook Integration Issues
ESET email protection keeps breaking my Outlook. Messages load slowly, attachments wonât open, and sometimes the whole program freezes. I tried reaching tech support through the ESET phone number, but the troubleshooting was basic and didnât fix anything. Customer support seemed unsure of the cause and kept transferring me. For a paid service, the constant interruptions make daily email work extremely frustrating.

Parental Control or Web Filtering Not Responding
The parental control feature on ESET barely works. Websites that should be blocked load anyway, and the web-filtering tool freezes constantly. I tried calling their customer support phone number, but the tech support team kept giving basic steps that didnât fix anything. For something thatâs supposed to protect kids online, this is really disappointing.

Technical Support Delays
I reached out to ESET for help with software errors, and the support response was painfully slow. Multiple emails went unanswered for days, and phone support left me on hold for long periods. By the time I got assistance, the issue had already disrupted my workflow. Extremely frustrating experience for a paid product.

False Positives and Detection Errors
Iâve been frustrated with ESET because it keeps giving false positives on files I know are safe. It slows down my system and interrupts work when it blocks programs or deletes files without explanation. Support was slow and didnât offer real solutions. This level of inaccuracy makes the software almost unusable.

Firewall and Network Issues
Since installing ESET, Iâve had ongoing issues with my network connections. The firewall often prevents normal programs from accessing the internet, and troubleshooting these blocks is complicated and time-consuming. It interrupts daily work and online activities regularly. Support responses were minimal and didnât resolve the underlying issues. Overall, the software feels overprotective and unreliable, making it hard to recommend.

Installation & Activation Problems
Installing ESET was a nightmare. The software kept failing to activate properly, and I had to repeat the process multiple times. Even when it finally installed, it blocked legitimate apps and websites without warning. Contacting support didnât helpâthey provided generic instructions that didnât solve anything. I expected a smooth and secure experience, but it has been a constant source of frustration.

Slow Performance / System Lag
Since installing ESET, my computer has been painfully slow. Trusted programs and websites are often blocked unnecessarily, which interrupts my work constantly. Customer service was polite but couldnât provide any real solutions to the problem. I purchased ESET expecting smooth, reliable protection, but it has caused more headaches than security. Extremely frustrating experience.

False Positives / Overblocking
ESET security software keeps giving false positives, overblocking websites and applications I trust. This constant interference makes daily tasks difficult, and customer support didnât offer any real solution. I expected reliable protection, but this service has been extremely frustrating.

Module Updates / Compatibility Issues
Compatibility issues started right after the latest module update, causing system conflicts and repeated crashes. Customer service keeps redirecting the problem without giving clear troubleshooting steps. The lack of proper guidance makes the issue even more irritating. Instead of smoother performance, each update adds new obstacles, turning a basic task into an exhausting process that never gets resolved.

Activation / License Key Problems
My ESET license key wouldnât activate, constantly showing server errors that made no sense. Customer service didnât bother to troubleshoot deeplyâthey just sent automated replies with steps I already tried. No real solution, no escalation, and no accountability. It felt like going in circles, and the issue stayed unresolved for far too long. Terrible experience.
