A friend gave me their computer to take a look at, since it was extremely slow and unreliable. It's an old HP Pavilion with 98SE, 10GB, and 64MB Ram. I managed to find an old memory stick (64). That immediately helped. The harddrive was approaching the critical point in fullness. I cleared a bunch of stuff and ran updates for all the programs. They were on dialup, so they hadn't updated anything since they got the computer. Yet, Adaware and Spybot both picked up trash. I'm thinking that most everything is taken care of, but I wanted to have you guys take a look at a log and see if there is anything else that I should be concerned with.

Thanks

That is a particularly short log and there is no apparent antivirus tool. AVG antivirus is compatible with WIN98:

Not sure what the deal was. I think I must have just deactivated it or something. I'm sure it was there. Either way, I reinstalled it. Not sure why the log is so short. I did do a partial reinstall of windows, so maybe that has something to do with it.

Anyway.... here's the new log:

Let us know if there are any further apparent issues.

It is nevertheless very underpowered with 128MB of RAM memory and currently is a much more risky platform given dialup access, and the ending and unavailability of any 'critical updates' for WIN98.
