Can't update or uninstall Avast Free
« on: July 14, 2016, 12:30:11 PM »
I have Avast Free version 2015.10.2.2218 installed, did install the next version but had problems with it so left it at that.

I just tried to update this, but got to "Saving package this may take a while" ... then nothing happened, tried twice.

Went to Add / Remove Programs >> "There was an error during product uninstallation", same on re-try.

I've downloaded Avast Uninstall Utility - should I go ahead with this, will it remove all traces?

Recently when I try to install programs I often receive this notice, even with Flash Player, which hasn't happened before:

"This file came from another computer and might be blocked to help protect this computer"

Have to go to 'Properties' and unblock each download now.

Don't know how to alter this setting or how it got put in place.

I am afraid that if I uninstall Avast Free I might not be able to reinstall it and I'll be left with no antivirus.

XP SP3 OS. Using Windows Firewall and have CryptoPrevent installed, no other security.

Please advise.

If your CPU supports SSE2...

1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

Thank you very much for helping Asyn.

Re: If your CPU supports SSE2...

I don't know....

It's an older computer - please see recent Speccy scan result (attached).

According to Speccy SSE2 is supported on your system.
So, please follow the instructions in Reply #1.

I just started the computer in Safe Mode.

Clicked on the Avast Uninstall Utility I had downloaded from your link. >>>

"instup.exe - Entry Point Not Found

The procedure entry point Get Logical Processor Information could not be located in the dynamic link library KERNEL32.dll."

I tried again, same.

I clicked on the Avast Uninstall Utility I had downloaded before coming here for help, same error message.

I noticed that the hard drive activity light was full on while I was doing nothing.

Looked at the running processes in Task Manager and saw explorer.exe using memory of 59,824 k, CPU 10-35.

?

What should I do now please?

OK, let's dig deeper...

Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)

Here are the logs...

MBAM and FRST scans were run recently - I can re-run them if you wish.

Some info for you...

I have been unable to access my bank's new online banking system. sfc (System File Checker) has been unable to copy a number of dll files into the dll cache.

I am receiving help with these issues.

For a while now under 'Applications' in Task Manager 'New folder' always shows. I sought help with regards this. Nothing malicious was detected, I was told it is an odd instance of explorer.exe.

I have found a previous download of Avast Uninstall Utility from last year that worked then, but because of the errors I am getting, I am worried that full uninstallation might fail or that I won't be able to install the latest version and I'll be left with no antivirus.

Your help is much appreciated.

Boot up in safe mode and go to program files and delete the avast folder, reboot and clean up with ccleaner

More bad advice. Even Linux needs protection. :)
