6) Just read this: a) Free Internet Window washer b) Free registry Cleaner, c) Registry helper, d) Windows Install Clean Up e) Pareto Logic's Regcure, f) Windows Defender, g) Windows Update and finally Microsoft's Update
Is the list above the components of Comhem's security package?
2) I've done one istallment of Comhem's security package
Again, what does that consist of? I suspect that package is the culprit here. Assuming it contains such tools as spam blocking, anti-virus, firewall, spyware protection/removal, etc., all that can be obtained from other programs, some of which you may already have installed.
4) I'm using Windows own firewall
If Comhem's security package contains a firewall, you probably have two firewalls enabled. That's not good. Only run one.
5) My ant-virus program is Windows own
Umm, Windows doesn't have it's own. So, please clarify what you have.
7 I have to admit that I don't know what "browser cache" is. Some kind of memory? Where do I find it?
Yup, it's a kind of memory. If you're using Internet Explorer, go to Tools, Internet Options, and click the Delete button under Browsing history. I suggest including Temporary Internet Files, Cookies, and History, for this troubleshooting exercise.
I'm defragmenting once or twice a year
Although I doubt that may not be a significant factor in this situation, you should still defragment much more often. The ideal frequency varies for each computer use, but I suggest you do it at least one time per month. The more often you do it, the less time it takes to defragment.
So, what should you do? Here's my thoughts:
1. Uninstall the Comhem's security package
2. Clear browser cache
3. Download CCleaner and run it's Windows scan and it's Registry scan. Remove all the items it finds. When running the Registry scan, backup the Registry when prompted. Repeat the Registry scan, since it may find more items upon a repeat scan.
4. Answer my questions so we have more info to go on. We need to know where you stand for firewall, anti-virus, and spyware protection, without having Comhem's security package installed.
For CCleaner, go to
