[Waverley ARS] I suspect a computer virus

[Henrik Stenstrom]

Gents,

I'm beginning to suspect that a computer virus is doing its dastardly
thing on our home PC. The unit in question is a Dell about 5 years old
running Windows XP and is used almost exclusively for internet/email and
other light duties.  Other details such as processor, RAM etc I can only
give after checking this evening.

Symptoms

The PC is seems to be running very slowly as if there are other programs
running in the background with higher priority.

Internet Explorer fails from time to time due to "runtime" errors

System requests from time to time to increase virtual memory levels


Attempts to Resolve

We have up to date Symantec Antivirus software installed.  Full system
scans do not show up any problem.

A recent Windows online update showed some initial improvement.

Increasing virtual memory levels is inconclusive.

Our ADSL connection might not be the fastest in Sydney but I don't
believe this is the underlying problem.


So, where to start?  Can anyone recommend if further anti
spyware/malware detection is required?  If so, any recommendations as to
what?  What else to check?  IS the windows task manager any use in
checking for other programs that are running?

Many thanks in advance for all or any help in resolving this aggravating
situation,

Henrik - VK2HHS
