Unable to open Windows XP

[Robersabel]

How do I correct problem of not being able to open by normal mode to Desktop?
Pressing F8 will not even open Safe Mode.
Have anti virus system PC-cilin. Ran scan every Monday, and did not reveal
contamination.
Security Center came on screen stating there are viruses, and trojans.

You were infested with malware.

Repair installation (in-place upgrade) might repair the damage enough for
you to log in/clean up - but my recommendation is to format, install clean
and this time use eSet NOD32 (antivirus only) and Malwarebytes (purchase
both) for protection beyond the Windows Firewall being enabled (with no
exceptions if plausible) and behind a NAT router. Don't want to spend the
$80-$85 U.S.? Avira AntiVir (free) combined with weekly manual update/scans
with MalwareBytes *might* keep you fairly clean.

I assume you mean product recovery with disc(s)?

Second of three computers now has contamination. Could not control so I
performed product recovery internally. Lost all data in TouchSmart Vista.
Did not improve.

Would purchasing product recovery disc(s) perform a clean computer,
eliminating all viruses?
