Hello. New here. Last weekend I foolishly opened an email attachment that installed malware. I used Malwarebytes to remove most of it, but in the process the Avast icon disappeared from the system tray and I get the following error when trying to open it.

 

C:\Program Files\Avast Software\Avast\AvastUI.exe

 

Windows cannot open this program because it has been prevented by a software restriction policy. For more information, open Event Viewer or contact your system administrator.

 

I also got a similar message on two occasions Malwarebytes found malware and needed to reboot. Upon rebooting this similar message appears.

 

It also seems that something for Avast is running, as there is an entry in Task Manager, but I cannot stop it.

 

I'm using XP, SP3, with an AMD Athlon 64 processor.

 

After doing some online searches it seems my computer still has some sort of infection or corruption. Can this be fixed? I'm no expert, but I can follow clear instructions if someone here is able to help.

 

Thanks!

No, I was reluctant to make any changes to the computer until I understood exactly what the problem is.

 

Thanks!

Reinstalling Avast would be a good start.

I'll backup my files this weekend and give that a shot.

 

Thanks.

Sorry it took so long. I've backed up everything and tried to uninstall Avast. Using Add Or Remove Programs, I was given a message that the program was already uninstalled. However all the files are still in place and Task Manager shows an entry for Avast which I am unable to end.

 

So I downloaded a new install file and ran it. It runs for a few seconds ("Avast self-extract") then ends and nothing else happens.

 

Trying to run the current version results in the same error message described in the original post.

 

Thanks.

That seems to have been successful. I'm going to wait a day or so then try to download and install it again. I'll be sure to post here either way.

 

Thanks.

You better install it now.

It's rather dangerous to operate without any AV program.

I reinstalled Avast earlier this week, and that day it worked fine. Now, however, I am having the exact same problem. I get the same error message and the entry in Task Manager cannot be stopped.

Part 3 failed, with this error message-

 

C:\DOCUME~1\Parents\LOCALS~1\Temp\UAgL8UWV.exe.part could not be saved, because the source file could not be read.

Try again later, or contact the server administrator.

 

I'll stop at this point and await further instructions.

 

Thanks!
