I was working on my older computer running windows system 7, I scheduled the virus boot-time scan and now it won’t start. I’m getting a black screen! What can I do? Help?
What version of Avast are do you have installed ?
Whilst I don’t really know why it didn’t start. The boot time scan normally downloads some virus signatures before running. If so some reason it was unable to do this I don’t know if this would stop the scan.
Was their a particular reason you wanted to run a boot time scan ?
I believe it was the latest version of Avast and I did click on the button that said to add the extra signatures…
I wanted to run it cuz I ran it on my newer computer, win 10, and it found 4 hidden viruses or something? I was curious what could be lurking…didn’t want to crash the darn computer tho!
If you don’t have a recovery disc, give this a try.

The much maligned Windows System Restore (possibly) coming to the rescue. 
That would have been the primary recommendation for something like this not so long ago: start in safe mode and use a restore point.
I really hope it works and he did not turn them off or uses a cleaner program regularly which often, ‘helpfully’, by default, removes all those supposed unnecessary restore points to free up more space.
That’s not a side swipe at CCleaner by the way as, unless it has been changed, it doesn’t do that. Some other similar cleaners and system ‘optimising’ software tools do.
Fingers crossed.
“That’s not a side swipe at CCleaner by the way as, unless it has been changed, it doesn’t do that. Some other similar cleaners and system ‘optimising’ software tools do.”
So why bring it up?
Because when you talk about PC cleaners the first thing that comes to mind for most people is: CCleaner which has been under the AVAST umbrella for some time now.
So I wanted to be sure people here understood that it was not one of the many PC cleaners/system optimisers tools that many people do use regularly that may delete all but the last restore point. That is unlike for instance PrivaZer which also wipes the hiberfil.sys file and takes it upon itself to turn off hibernation by default. Both annoying features even though that behaviour can be changed in the settings.
In short it was a positive comment on CCleaner which, I thought, would be welcome on this forum. I’m not sure how it could have been interpreted in any other way.
Did you read the title of this topic? It has nothing to do with PC cleaners.
The information you provided the OP with to deal with the problem in the absence of a recovery disc was a link to a Dell sponsored tutorial on how to use System Restore.
To use System Restore you need to have a restore point or points other than the current one. As I said, many people use PC cleaners/optimising software which may, by default, ‘clean’ all restore points except the current one. Users only discover this when they try to use System Restore.
We can not tell if this applies to the OP or not but he might at least be interested to know the possible reasons why he does not have any restore points. If that proves to be the case he might want to do something about that in the future. Hence my post.
CCleaner does not clear restore points by default and also includes what I’ve always found is one of its most useful additional features: a basic restore point manager. You can check your restore points very quickly and delete those you do not need without having to go via the longer Control Panel route.
So why not wait till there’s a reply from the user before rattling off about one of your pet peeves?
Just trying to be helpful pre-empting the possible problem and providing an explanation if , unfortunately, not a solution.
Instead of being, inexplicably, irked about this wouldn’t providing an alternative pre-emptive solution, if restore points are not available, that the OP could use have been more helpful?
Threads like this with a clear description of the particular trouble in the subject field are likely going to be featured in future search result by countless others. Detailing the possible problems and offering as much information and a range of possible solutions that might be applicable may help others even if some of it turns out not to be relevant to the OP.
“description of the particular trouble in the subject field are likely going to be featured in future search result”
All the more reason not to include items that have nothing to do with the topic.
Your unnecessary remark regarding Ccleaner is certainly one of those.
I think I’ll leave it there - I can not be bothered having to defend, inexplicably, a genuine attempt to be helpful with possibly relevant information and a post which had positive things to say about an AVAST tool.
“a post which had positive things to say about an AVAST tool.”
“That’s not a side swipe at CCleaner by the way as, unless it has been changed, it doesn’t do that.”
[/size]If that was a positive comment, I’d hate to see a negative one. Enough said.
