Author Topic: How to scan when booting W7 PC? (Read 4813 times)

melissajkelly · « **on:** December 22, 2012, 03:51:15 PM »

Two days ago I watched a video online that apparently had a v i r us in it. My Avast didn't go off when I viewed it, but a friend who viewed it on her work PC 5 minutes later got the v i r us. I ran Avast to see if my system was clean, and it found several threats that I moved into the chest. When that was done, it asked whether I wanted to run the program while the PC was booting. I said yes and went to work.

When I came home 9 hours later I had a DOS screen that looked like nothing was happening so I hit the ESC key. That's when I figured out it must have still been running.

It said it found one threat but there was no other info on what it was or how to get rid of it.

So...I want to re-run Avast Antivirus during boot but can't find where/how to do that. Can someone tell me what to do? (I'm on Windows 7 64-bit.)

Thanks!

Hello and welcome to the forum!

Open avast --> Scan Computer --> Boot-time Scan --> Schedule now. In the settings you can adjust the scan options before scheduling it.

Thanks for the quick reply. I don't have that option. I have:

Quick Scan
Full System Scan
Removable Media Scan
Select Folder to Scan (it doesn't appear that I can select boot in there anywhere)

Any ideas?

Thanks,
Melissa

Open Avast.In the left hand column click on scan computer. you should see an option to scan now,underneath that is the option for boot time scanThen follow DJBone's directions.

Thanks. Now I see it.

I have a huge hard drive so I know it's going to take a while to run (since last time it wasn't done in 9 hours)...so I wanted to ask a question before running the boot scan. Will Avast fix/quarantine anything it finds there? (It looked different being in more of a "DOS screen" last time; and it didn't fix the one threat that was found when I aborted it.)

Thanks,
Melissa

Thanks. I have run the scan numerous times. I keep getting "virus found" in the boot scan. On several scans I selected "move to chest"---when I check my log it doesn't say that a file was moved to the chest. The second-to-the-last time I ran the boot scan I requested that it "delete" the file. Yet when I ran it again, it still says virus found.

Please see attached screen capture.

What do I do? Thanks, in advance, for your help.

Could you please post a screenshot of the last Scan Log?

PS: Never choose delete as option for possible malware because it could be a false poritive. Choose move to chest.

I ran the full computer scan again last night. This time there were some files that couldn't be scanned (because it said they were password projected); but I didn't get a virus message this time. Maybe choosing "delete" last time (on an ancient archived e-mail file) did the trick.

Attached is that screen shot.

I will run the "boot scan" again today while we're gone; hopefully it will come back clean now.

I chose "delete" because I located the file it was saying was a virus and determined I didn't need it. I knew there was a risk it would tag something else that I needed...but figured the odds were with me that it wouldn't since I had already run the scan so many times this week.

Thanks!

Double click on a specific scan result/log. Then post the screen shot. It should look something like my screenshot only with actual virus/malware.

Thanks--didn't realize they were clickable!!! LOL Attached.

I think it's time to call in a malware expert. Be patient one will be with you shortly.

The file in question was an old e-mail archive file. It has now been deleted from the PC.

Still need the Malware expert?
