I just installed avast! from the file setupeng, as I also had the error 301 trying to install from the downloader.
Now Win XP says my antivirus software is out of date.
I run iAVS and get this response:
Information about current update:
Total time 5 s
Vps: Already up to date
(current version 091015-0)
First - Ensure yoyr system date is correct day/month/year and adjust as required.
Second - Try a repair of avast. Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow. This has in the past resolved this out of sync issue between reported and actual VPS version.
Third - If the above don’t have any impact jet back to the topic as the Windows Security Center can be a little flaky and we have a couple of tips for that.
The same problem is happening with me. I did the repair method which you suggested and that didn’t seem to correct the Windows issue. Any other tips for Windows Security Center?
