antivirus will not update

Computer Aid Posted on by

Strange problem… While setting up wireless internet, I also remove norton from a customer computer.

After installing the usual (antivir, defender, spywareblater, winpatrol, I find that antivir will not update.

I don’t want the PC to run with virus definitions that are a few months out of date, so I take the PC back to the office.

Its only then that I notice my own PCs will not update antivir…

I eventually find that the antivir servers had been overloaded (due to an unusually large update)… it all starts working normally just a few days later.

Looks like I assumed the worst, but the problem turned out to be out of my control.

Antivir guard doesn’t automatically start (XP minifilters problem)

As most of you know, I’m a big fan of Avira Antivir. Its a great antivirus, and it also detects many spyware programs as well.

One of my annoyances is the daily advert it displays on my screen (its actually not very annoying… I know I can get rid of the ad by paying for antivir).

The other annoying aspect, is that occasionally, it will be unable to automatically run the “realtime” scanner (avguard). The symptom is a closed umbrella symbol in the taskbar. Usually, a restart fixes it.

But when a restart doesn’t start avguard, I’ve noticed that uninstalling and reinstalling antivir will not fix the problem either.

I also tried cleaning any registry reference to antivir and avira, but the problem persists.

In the past, my “plan B” was to install AVG.

I recently stumbled onto a solution:

This seems to fix the problem very nicely.

I also learnt a bit about the XP (NT) minifilter system in the process.
