i noticed that my other computer was INSECURED today. pressing ‘fix now’ and subsequently ‘restart program’ has no effect. can anyone help?
Try a repair of avast:
XP - Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and select Repair, click next and follow.
Vista, win7 - Control Panel, Programs & Features, uninstall a program, select ‘avast! Anti-Virus,’ click the Uninstall/Change and select Repair, click next and follow.
You should reboot after the repair.
Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?
thank you DavidR, worked exactly as you said. normally my kids help me out with this but they’re not around. if you have a moment for further advice; avast blocked two trojans last night, could that be related to the problem do you think, i’ve started a boot scxan right away…2:15plemarks
It could be related but (I doubt it) without more information impossible to say.
How were they detected, routine on-demand scan, web shield alert, etc. ?
What was the file name, malware name and full location (what folder was it detected) of the two detections ?
have to wait till boot scan runs to tell you about trojans, meanwhile scan is saying ZIP archive corrupted error 42125… mean anything to you? ea
Hi,
- Try a good old run with malwarebytes free, and download it and fully update it, and do full scan . & delete any thing it finds.
- Reboot and re scan with avast on boot time scan and remove any thing what this finds.
Files that can’t be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.
Many programs (usually security based ones) password protect their files for legitimate reasons, there are others (and avast doesn’t know the password or have any way of using it even if it did know it).
When you run scans with the above programs and you delete harmful entries that they detect, a copy is kept (in quarantine/restore/backup) in case you need to reverse what you did. These are usually password protected, you should do some housekeeping and delete old backup/recovery/quarantine entries (older than two weeks or so), this will reduce the numbers of files that can’t be scanned.
Normally archive files aren’t scanned as they are inert, e.g. you have to extract the contents and run them, before that happens the on-access scanner would scan them. However, the boot-time scan scans archives by default, there is nothing you as a user can do about a corrupt archive, it may just be that for whatever reason avast is unable to unpack it to scan the contents.
So this error is just a notification that a file can’t be scanned and why.
Please don’t give advice which could adversely effect a users system.
Don’t remove (delete) anything especially in a boot-time scan. Deletion isn’t really a good first option (you have none left), ‘first do no harm’ don’t delete, send virus to the chest (a protected area) and investigate.
For files that can’t be scanned I don’t believe avast would allow deletion as it isn’t infected, but that is in a normal scan. I don’t know how avast would react in a boot-time scan, but it isn’t a good habit to get in by deletion as a first option.
DavidR do you recommend using malwarebytes alongside avast? do they complement each other?
While David is away (probably sleeping), I will answer and the answer is YES.
MalwareBytes AntiMalware (MBAM) is often suggested with Avast and most of us here use it as a back-up scanner.

great, i used to use it but was told i shouldn’t, thanks for the advice. how can i find out about the trojans that avast blocked 36 hours ago?
