Issue with the virus detected.
I might try Defender even though I generally dislike antivirus software. I haven’t caught any viruses with or without it. Removing Avast caused my disk usage to spike unexpectedly, making the computer nearly unusable. That’s frustrating on its own, so I’d prefer using AdwCleaner or MBAM occasionally instead of letting the AV constantly update or warn me about issues.
Windows Defender (or MSE on Windows 7 – Windows Defender on Windows 7 isn’t a complete antivirus program) won’t cause issues unless something is amiss. You might see a system tray alert indicating a scan hasn’t been performed recently, but you can safely disregard it for now. What are your PC’s details? How long has Windows gone without a full cleanup and reinstall? Avast shouldn’t show the kind of behavior you’re describing. I’ve tested it on numerous setups and it won’t make the machine nearly unusable unless I run a comprehensive scan, which it won’t do automatically. Regularly updating AV software is important because it guarantees you have the most recent virus definitions to fight off threats. A reliable AV should update quietly. Avast also offers a “gamer” mode that silences the program and prevents interruptions or unexpected updates, avoiding lag or ping issues.
Regarding the details, my machine features an older C2 Quad with 6GB of DDR2 RAM. The main limitation comes from a 5400 RPM HDD (sufficient for Windows 8, though I have a faster 7200 RPM one for Windows 7 running Avast). Having a slow HDD that occasionally slows down is bothersome. It was recently installed in July, and I keep the fragmentation under 5%. I also enable gamer mode on Avast, but sometimes Defender sends annoying messages on other systems. Currently, my laptop uses an SSD with no AV software installed; everything is backed up elsewhere just in case. Windows was reinstalled about two weeks ago (Lenovo bloatware that I didn’t want). For now, I’m content with the performance. I’ll test Defender for a day again to check if the slowdown is justified.
I suggest AVG or Avast for basic free defense. My top choice is AVG, it provides numerous useful tools such as an identity protection feature that executes unknown programs in an emulator and ranks applications based on safety, making it a strong blocker. It also offers excellent detection capabilities. Recently AVG acquired Norman Security, which could add extra safeguards; I haven’t heard much about its future plans yet. For paid options, Kaspersky, Eset and Bitdefender are all solid choices. Many believe they match free versions, but this isn’t accurate. They include advanced features like ASLR, DEP, custom firewalls that adapt in real time, and intrusion detection systems that boost identification. Eset is simple, but enabling its HIPS or Host Intrusion Prevention System will warn you about suspicious changes to registry keys and files. It’s not turned on by default, but you can activate it. Regardless, always layer your security. Ensure you have: 1) Antivirus, 2) An anti-exploitation tool like Microsoft EMET or Malwarebytes AE, 3) A firewall, 4) A second scanner for monthly checks. This is crucial because modern threats often hide in the boot sector, making them hard to detect. Using antivirus—even Windows Defender—is essential to reduce infection risks.
Challenge the notion that common sense alone can prevent viruses. Discover various methods of infection, then engage with discussions like this.
You're asking about detection results and the limitations of certain antivirus tools. It seems like you want a clear summary of what was observed during the scan. The findings suggest some variants weren't identified by Bitdefender, while malwarebytes managed to catch others. Kaspersky also didn’t find what was expected. This highlights the importance of using multiple security solutions for comprehensive protection.
In reality, each AV Vender will review what they detect and when the virus enters the wild. Kaspersky may catch things BitDefender overlooks, while Malwarebytes might spot issues neither of them noticed. Still, it’s a fairly outdated idea that common sense alone is sufficient. The modern internet makes this approach insufficient. EDIT: See this insight on why common sense falls short: http://lifehacker.com/why-you-should-use...-476330249 Zero day exploits pose the greatest threat. These are vulnerabilities that remain undiscovered or unpatched, and they can compromise you even with No-script and AdBlocker active, plus Java turned off, since they can bypass security gaps not yet understood by browsers.
