I’m working on my Husbands PC running Vista Home Premium. It was running super slow. Uninstalled a few things and ran a Quick scan, then uninstalled a few more things, turned off Windows Defender and firewall went in to scan with a boot scan and noticed that the drop down no longer shows deep scan, quick scan, scan a file… it only shows boot scan.
Any ideas on why this happened?

Danke Uber… I’ll give that a try tomorrow. It’s 2am right now and I’m mighty tired.

Sorry it took me so long to get back to this. I went into control panel and repaired the Avast internet security. I came back to it today and it still only shows Boot Scan in the drop down menu for the scans.
Any other suggestions or do I need to remove this and start over?
You need to perform a clean install:
Note: It’s important you used the stub online installer from the one I linked… NOT the offline one.
Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn’t)
1.Download your version of avast! and the avastclear tool:
Avast Free Antivirus
Avast Pro Antivirus
Avast Internet Security
Avast Premier
Download Avast Clear Tool
- Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #3]
- Uninstall in safe mode using Avastclear. [Running Avastclear is normal mode will give a prompt to go into Safe Mode]
Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle… if so, uninstall it and reboot.
- Install the version you downloaded.
- Reboot.
Free: If you have the Free version, register the product for free for a year from the avast! UI.
Paid: If you have a paid license, insert the license key/activation code after the reboot at stage 6.
If you have any questions, please don’t hesitate to ask. It’s better to ask than make a mistake and start over again with the process.
