Hi, Good day!

My problem is that I can't install any anti-virus on a PC... I strongly believe it has many viruses because it slow-ups the unit. Almost all of the anti-virus I run (Avira, Avast, KIS, KAV and AVG) cannot install successfully as if being destroyed or blocked by something.

I am looking forward for any help from the community.


Best regards,

coldflame

A short, practical plan to follow when AV installers keep failing (builds on suggestions from , , and but adds concrete steps you can use right away).

  1. Isolate and protect data
  • Immediately unplug the machine from networks. Do not use it for browsing or email.
  • Back up only personal documents (documents, photos). Avoid copying programs, installers, or macro-enabled Office files unless you scan them first on a known-clean machine.
  1. Quick triage (non-destructive)
  • Try Safe Mode to uninstall obvious junk and stop nonessential startup items. Look for suspicious scheduled tasks, services and startup entries.
  • If installers still fail, create a bootable rescue USB from a different, clean PC and run a full offline scan. If that is not possible, remove the drive and connect it as a secondary disk to a clean machine and scan it there.
  1. Look for persistence points the malware uses
  • Inspect startup areas: scheduled tasks, drivers, services, and the hosts file. Use a trusted startup-inspection tool on a clean system to review entries before re-enabling them.
  • If you find unsigned drivers, unknown services, or hidden scheduled tasks, quarantine them and scan again.
  1. When to reimage
  • If infections are widespread, boot records or system files look compromised, or AVs still cannot install after offline cleaning, reimage the system from a known-good source. Reinstallation is the most reliable long-term fix.
  1. Recovery and prevention after a clean system
  • Before reconnecting, fully patch OS/firmware and change all passwords used from the infected machine. Restore only scanned data. Create a daily backup routine and run periodic offline scans. For shared/branch environments, apply least-privilege accounts, network segmentation and centralized update/AV management.

Extra notes: avoid copying executable files from an infected machine, and if a removal fails or you see persistent blocking at boot time, consider professional help — some threats operate at a very low level and are hard to remove safely.

Hi Alternatively you can run avg from boot disk,the only thing you might have to pay for the disk.It used to be free.

What windows version are you using?

Are you able to install any application? Are you able to uninstall applications? If you are able to do both install Revo Uninstaller first then go into safemode and uninstall all the unnecessary applications.

Then install Malwarebytes http://www.malwarebytes.org/ and scan the system after disconnecting from the internet (just a precaution anyway).

If all this fails, please let me know.

also before you run the scan run it in safe mode
and if u r running IE or chrome be warned it will change your proxy settings

Thank you so much...ALL of you for helping me in this problem. What i did was just an easy process. I have just reformatted the PC, only the C:, and install a Kaspersky Anti-Virus Trial Version. It requested to connect to the internet because of some infected files in DLL types. Some of it are malicious codes that causes harm to the PC, that's what I've suspected. After it, it asked to disinfect all those infected DLL files and asked to restart the PC. Anyway, the scanned viruses, worms, trojans and other harmful shits were 800+ as detected by the KAV. That's what I did. All of there things were caused by those fucking stuffs. We'll, I can't blame myself nor the PC. I have blamed the users in a Branch where all of them are STUPID. That's what I've learned in college. As an IT, we have all there STUPID USERS. lol
